Keegan deposited $675 in a savings account that pays 4.8% annual interest compounded quarterly.
Write the compound interest formula to represent Keegan's investment after 5 years.
How much money will Keegan have in the account after 5 years?

Answers

Answer 1

Keegan will have approximately $878.85 in the account after 5 years.

What is Compound interest ?

Compound interest is the interest that is earned not only on the initial amount of money invested (known as the principal), but also on any interest earned on that principal over time. In other words, compound interest is interest on interest.

The compound interest formula is given by:

A = P[tex](1 + r/n)^{nt}[/tex]

where A is the amount after t years, P is the principal amount, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the time in years.

In this case, Keegan deposited $675, the annual interest rate is 4.8%, the interest is compounded quarterly, and the investment is for 5 years. Therefore, we can plug in these values into the formula to get:

A = 675[tex](1 + 0.048/4)^{20}[/tex]

A = 675[tex](1.012)^{20}[/tex]

A ≈ $878.85

Therefore, Keegan will have approximately $878.85 in the account after 5 years.

The first box and whisker plot

Step-by-step explanation:

A box and whisker plot gives you the five number summary for a set of data.  The five number summary is

The minimum/lowest value (looks like the top of capital T turned sideways and is the leftmost part of the box-and-whisker plot The first quartile or Q1, representing 25% of the data (the first point represented in the "box" of the plot and serves as an endpoint of the box)The median or Q2, representing 50%/the middle of the data (the line that splits the box into two parts/the line in the middle of the box)The third quartile or Q3, representing 75% of the data (the last point represented in the "box" of the plot and serves as another endpoint of the box)The maximum/highest value (also looks like the top of capital T turned sideways and is the rightmost part of the box-and-whisker plot

Maximum and minimum:

We know from the data that the minimum value is 100 and the maximum value is 200.  However, because both boxes available as answer choices have the correct minimum and maximum, we'll need to find more data.

Median:

We can start finding the median first by arranging the data from the least to greatest.  Then, we find the middle of the data.  Because there are 9 points and 9 is odd, we know that there will be 4 points to the left of the median and 4 points to the right of the median:

100, 100, 120, 120, 150, 165, 180, 180, 200

150 has 4 numbers both on its left and right sides so its the median.

Because both of the plots available as answer choices have the correct median, we we'll need to find more data.

First Quartile/Q1:

In order to find Q1, we must find the middle number of the four numbers to the left of the median.

Because we have an even number of points, we will get two middle numbers, 100 and 120.  To find the middle of all four points, we average these two numbers:

(100 + 120) / 2 = 220 / 2 = 110

Only the first box has the accurate Q1 value, so it's our answer.

We don't have to find Q3, since both boxes have the correct Q3, but only the first box has the correct minimum, correct Q1, correct median, correct Q3, correct maximum.

Find the volume of the solid generated by revolving the region enclosed by x= v5y2, x = 0, y = - 4, and y = 4 about the y-axis.

Answers

To find the volume of the solid generated by revolving the given region about the y-axis, we can use the method of cylindrical shells.

First, we need to sketch the region and the axis of rotation to visualize the solid. The region is a parabolic shape that extends from y = -4 to y = 4, and the axis of rotation is the y-axis.

Next, we need to set up the integral that represents the volume of the solid. We can slice the solid into thin cylindrical shells, each with radius r = x and height h = dy. The volume of each shell is given by:

dV = 2πrh dy

where the factor of 2π accounts for the full revolution around the y-axis. To express r in terms of y, we can solve the equation x = v5y2 for x:

x = v5y2
r = x = v5y2

Now we can integrate this expression for r over the range of y = -4 to y = 4:

V = ∫-4^4 2πr h dy
 = ∫-4^4 2π(v5y2)(dy)
 = 80πv5

Therefore, the volume of the solid generated by revolving the given region about the y-axis is 80πv5 cubic units.
To find the volume of the solid generated by revolving the region enclosed by x = √(5y²), x = 0, y = -4, and y = 4 about the y-axis, we can use the disk method.

The disk method involves integrating the area of each circular disk formed when the region is revolved around the y-axis. The area of each disk is A(y) = πR², where R is the radius of the disk.

In this case, the radius is the distance from the y-axis to the curve x = √(5y²), which is simply R(y) = √(5y²).

So the area of each disk is A(y) = π(√(5y²))² = 5πy²

Now, we can find the volume by integrating A(y) from y = -4 to y = 4:

Volume = ∫[A(y) dy] from -4 to 4 = ∫[5πy² dy] from -4 to 4

= 5π∫[y²2 dy] from -4 to 4

= 5π[(1/3)y³] from -4 to 4

= 5π[(1/3)(4³) - (1/3)(-4³)]

= 5π[(1/3)(64 + 64)]

= 5π[(1/3)(128)]

= (5/3)π(128)

= 213.67π cubic units

The volume of the solid generated by revolving the region enclosed by x = √(5y²), x = 0, y = -4, and y = 4 about the y-axis is approximately 213.67π cubic units.

work out the donation to charity b.

Answers

If the donation to charity b is 5/6 of the donation to charity d, charity d's donation is twice the donation to charity c and the ratio of donations for charity c to charity a is 3:4 then the donation to charity b is £1250.

Let's denote the donation to charity a as x. Then the donation to charity c is (3/4)x, and the donation to charity d is 2(3/4)x = (3/2)x.

We know that the donation to charity b is 5/6 of the donation to charity d, so:

donation to charity b = (5/6)(3/2)x = (5/4)x

We also know that the total donation is £4500, so we can set up an equation:

x + (3/4)x + (3/2)x + (5/4)x = £4500

Multiplying through by 4 to get rid of the fractions, we have:

4x + 3x + 6x + 5x = £18,000

18x = £18,000

x = £1000

So the donation to charity b is: (5/4)x = (5/4)(£1000) = £1250

Therefore, the donation to charity b is £1250.

In order to estimate the mean 30-year fixed mortgage rate for a home loan in the United States, a random sample of 10 recent loans is taken. The average calculated from this sample is 6. 40%. It can be assumed that 30-year fixed mortgage rates are normally distributed with a population standard deviation of 0. 5%. Compute 95% and 99% confidence intervals for the population mean 30-year fixed mortgage rate

Answers

The 95% confidence interval for the population mean 30-year fixed mortgage rate is (6.091%, 6.709%), and the 99% confidence interval is (5.993%, 6.807%).

To estimate the mean 30-year fixed mortgage rate for a home loan in the United States using a random sample of 10 recent loans with an average of 6.40% and a population standard deviation of 0.5%, you can compute the 95% and 99% confidence intervals as follows:

1: Identify the sample mean (x), sample size (n), and population standard deviation (σ).

x = 6.40%

n = 10

σ = 0.5%

2: Calculate the standard error (SE) using the formula SE = σ/√n.

SE = 0.5%/√10 ≈ 0.158%

3: Determine the critical z-values for 95% and 99% confidence intervals.

For a 95% confidence interval, z = 1.96 (from the z-table)

For a 99% confidence interval, z = 2.576 (from the z-table)

4: Calculate the margin of error (ME) using the formula ME = z * SE.

For 95% CI,

ME = 1.96 * 0.158% ≈ 0.309%

For 99% CI,

ME = 2.576 * 0.158% ≈ 0.407%

5: Compute the confidence intervals by adding and subtracting the ME from the sample mean.

95% CI:

(6.40% - 0.309%, 6.40% + 0.309%) = (6.091%, 6.709%)
99% CI:

(6.40% - 0.407%, 6.40% + 0.407%) = (5.993%, 6.807%)

So, the 95% confidence interval and 99% confidence interval is (6.091%, 6.709%) and (5.993%, 6.807%) respectively.

When you use a debit card to make a purchase, the money is deducted directly from your bank account. Debit cards do not typically charge interest like credit cards do, so C is not correct.

A is also not correct since most banks do not charge a fee for using a debit card, although some may charge fees for using an out-of-network ATM or overdraft fees if you spend more than you have in your account. B is not a typical characteristic of debit cards either, as there is generally no connection between a store's loyalty program or discounts and using a debit card for payment.

 A customer is comparing the size of oil funnels in a store. The funnels are cone shaped. One funnel has a base with a diameter of 8 in. And a slant height of 12 in. What is the height of the funnel? Round your answer to the nearest hundredth. 

Answers

The height of the funnel is 11.31, under the condition that one funnel has a base with a diameter of 8 in. And a slant height of 12 in.

Here we have to apply the Pythagorean theorem to evaluate the height of the funnel. The Pythagorean theorem projects that the square of the hypotenuse (the slant height) is equal to the sum of the squares of the other two sides (the radius and height).

Now, we have a cone that has a base diameter of 8 inches which says that the radius is 4 inches. The slant height is 12 inches. Then the height is
h² + r² = l²
h² + 4² = 12²
h² = 144 - 16
h² = 128
h = √(128)
h ≈ 11.31

Hence, 11.31 inches is the approximate height of the funnel after rounding to the nearest hundredth.

Brainliest if correct!_A particle is projected vertically upwards from a fixed point O. The speed of projection is u m/s. The particle returns to O 4 seconds later. Find:

a) the value of u

b) the greatest height reached by the particle

c) the total time of which the particle is at a height greater than half its greatest height

Thank you so much!

Answers

The value of the velocity, u is 19.6 m/s.

The greatest height reached by the particle is 19.6 m.

The total time during which the particle is at a height greater than half its greatest height is 2.33 s.

What is the value of the velocity, u?

a) To find the value of the velocity, u, we can use the formula for the time of flight of a vertically projected particle:

t = 2u/g

Since the particle returns to the same point after 4 seconds, we have:

2t = 4

Substituting the value of t in the first equation, we get:

u = gt/2 = 9.8 x 2

u = 19.6 m/s

b) To find the greatest height reached by the particle, we can use the formula for the maximum height reached by a vertically projected particle:

h = u^2/2g

Substituting the value of u, we get:

h = 19.6^2/(2 x 9.8)

h = 19.6 m

c) To find the total time during which the particle is at a height greater than half its greatest height, we can first find the height at which the particle is at half its greatest height:

h/2 = (u^2/2g)/2 = u^2/4g

Substituting the value of u, we get:

h/2 = 19.6^2/(4 x 9.8) = 24.01 m

So, the particle is at a height greater than half its greatest height when it is above 24.01 m.

Next, we can find the time taken by the particle to reach this height:

h = ut - (1/2)gt^2

24.01 = 19.6t - (1/2)9.8t^2

Solving this quadratic equation, we get:

t = 2.33 s or t = 4.10 s

The particle takes 2.33 s to reach a height of 24.01 m, and it takes another 1.67 s (4 - 2.33) to return to the ground.

The mean weight of the team is approximately ___ pounds.
(Round to the nearest​ tenth.)

Answers

Answer: The mean weight of the 11-person team is 207.3 pounds

Step-by-step explanation:

According to the question,

The mean weight of 4 backfield members = 234 lb
Therefore, the total weight of 4 backfield members = 4 × 234 = 936 lb

Similarly,
The mean weight of the 7 players = 192 lb
And the total weight of 7 players = 7 × 192 = 1344 lb

∴ Total weight of 11 players = (936 + 1344) lb = 2280 lb

We know that,

Mean =  [tex]\frac{Total Sum}{Total number of variables}[/tex]    

∴ To find the mean weight of the 11 players we need to divide the total weight by 11 :

Mean = [tex]\frac{2280}{11} = 207.27[/tex]

Rounding off to the nearest tenth we get,
Mean = 207.3

Hence, the mean weight of the team is approximately 207.3 pounds



Tim made his mother a quilt. The width is 6 5 /7 ft and the length is 7 3 /5 ft. What is the area of the quilt?

Answers

The quilt's area is approximately 60.74 square feet.

How to calculate the quilt's area?

To calculate the area of the quilt, we need to multiply the width by the length.

First, we need to convert the mixed numbers to improper fractions:

Width: 6 5/7 ft = (7 x 6 + 5)/7 = 47/7 ft

Length: 7 3/5 ft = (5 x 7 + 3)/5 = 38/5 ft

Now, we can multiply the width by the length:

Area = width x length

Area = (47/7) ft x (38/5) ft

Area = 2126/35 sq ft

Area ≈ 60.74 sq ft

C. The group raised $22.50 per car.
D. The relationship is not a direct proportion.

Answers

Answer:

The correct answer is D. The relationship is not a direct proportion.

We can see that the money raised is not directly proportional to the number of cars washed. For example, when the number of cars washed is doubled from 3 to 13, the money raised is not doubled from $43.50 to $87.00. Instead, it is increased by a factor of 6.5, from $43.50 to $279.50. Similarly, when the number of cars washed is increased by 5 from 13 to 18, the money raised is increased by a factor of 1.4, from $279.50 to $405.00.

This suggests that the amount of money raised is not simply a linear function of the number of cars washed. Instead, it is likely a more complex function that takes into account other factors, such as the time of day, the weather, and the location of the car wash.:

Answers

Step 1: Answer

The point (2, 8) is the point (x1, y1) identified from the equation y - 8 = 3(x - 2).

Step 2: Explanation

The equation y - 8 = 3(x - 2) is in point-slope form, which is y - y1 = m(x - x1), where (x1, y1) is the point on the line and m is the slope of the line. In this case, the slope of the line is 3, which means that for every increase of 1 in the x-coordinate, the y-coordinate increases by 3.

Comparing the given equation with the point-slope form, we can see that x1 = 2 and y1 = 8. Therefore, the point (2, 8) is the point identified from the equation.

Marsha is considering purchasing 3 points on a $350,000 home mortgage for 20 years. If she
purchases the 3 points, at a cost of 1 percent per point, her monthly mortgage would be
approximately $1,878.63. If she decides not to purchase any points, Mercedes' monthly
payment would be approximately $1,987.13. How much money will Mercedes save over the life
of the loan if she purchases the 3 points?

Answers

Marsha would save $26,040 over the life of the loan if she purchases the 3 points.

First, let's calculate the monthly payment if Marsha doesn't purchase any points. We can use a mortgage calculator or the PMT function in Excel to find;

PMT = $1,987.13

Now, let's calculate the monthly payment if Marsha purchases 3 points;

Loan amount = $350,000

Points cost = 3 points × 1% × $350,000 = $10,500

Effective loan amount = $350,000 - $10,500 = $339,500

Interest rate = 4.5% / 12 = 0.375%

Number of payments=20 years × 12 = 240

Using the PMT function, we get;

PMT = $1,878.63

So, by purchasing 3 points, Marsha can save;

$1,987.13 - $1,878.63 = $108.50 per month

Over the life of the loan, which is 20 years or 240 months, the total savings would be;

$108.50 × 240 = $26,040

An oil tanker and a cruise ship leave port at the same time and travel straight-line at 32 mph and 46 mph, respectively. Two hours later, they are 63 miles apart. What is the angle between their courses?​

Answers

The angle between their courses is 42.02°.

How to calculate angle between 2 moving bodies

It is important to first find the distance between them after the 2 hours of travel.

Recall the  formula:

speed = distance/time

Make distance the subject of the formula

distance = speed x time

For the oil tanker,

given the following:

speed = 32mph

time = 2hr

distance = 32 mph x 2 hours = 64 miles

For the cruise ship,

given the following:

speed = 46 mph,

time = 2 hr

distance = 46 mph x 2 hours = 92 miles

So after two hours of travel, the two vessels are 63 miles apart. This means that they are forming a triangle with the distance between them as the longest.

Now we need to find the angle between the two vessels' courses by using the Cosine rule:

Recall that

a² = b² + c² -2bc Cos A

Let C be the angle between the oil tanker and cruise ship

then we can rewrite the equation as:

c² = a² + b² -2bc Cos C

where

a = 64miles (distance of oil tanker)

b = 92miles (dsitance of cruise ship)

c = 63miles (distance between the vessels)

C = angle between the vessels

Plug in the values to the equation

63² = 64² + 92² - 2(64)(92) Cos C

3969 = 4096 + 8464 - 11776 Cos C

3969 = 12560 - 11776 Cos C

Collect like terms

3969 - 12560 = - 11776 Cos C

8591 = 11776 Cos C

Cos C = 8591/11776

Cos C = 0.7295

Apply the inverse Cosine formula

C = Cos⁻¹ (0.7295)

C = 42.02°

Find two acute angles that satisfy the equation sin(3x + 9) = cos(x + 5). check that your answers make sense.

Answers

The equation sin(3x + 9) = cos(x + 5) has no solutions in the set of acute angles.

What are the acute angles that satisfy sin(3x + 9) = cos(x + 5)?

To find two acute angles that satisfy the equation sin(3x + 9) = cos(x + 5), we can use the trigonometric identity cos(x) = sin(π/2 - x) to rewrite the right-hand side of the equation as follows:

sin(3x + 9) = cos(x + 5)sin(3x + 9) = sin(π/2 - x - 5)3x + 9 = π/2 - x - 5 + 2πn or 3x + 9 = x + 5 + 2πn + π (where n is an integer)4x = -4 - 2πn or 2x = -2πn - 4 or 2x = π - 2πn - 4

Dividing both sides of the equation by 4, we get:

x = -(1/2)πn - 1

So the solutions are given by:

x = -(1/2)π - 1 and x = -(3/2)π - 1

To check that these solutions make sense, we need to ensure that they are acute angles, i.e., angles that measure less than 90 degrees.

The first solution, x = -(1/2)π - 1, can be written in degrees as:

x ≈ -106.26 degrees

This angle is not acute, so it is not a valid solution.

The second solution, x = -(3/2)π - 1, can be written in degrees as:

x ≈ -286.87 degrees

This angle is also not acute, so it is not a valid solution.

Therefore, there are no acute angles that satisfy the equation sin(3x + 9) = cos(x + 5).

Barbara’s Bigtime Bakery baked the world’s largest chocolate cake. (It was also the world’s worstcake, as 343 people got sick after eating it. ) The length was 600 cm, the width 400 cm, and the height 180 cm. Barbara and her two assistants, Boris and Bernie, applied green peppermint frosting on the four sides and the top. How many liters offrosting did they need for this dieter’s nightmare? One liter of green frosting covers about 1200 cm²

Answers

The total liters of frosting needed is 500, under the condition that the length was 600 cm, the width 400 cm, and the height 180 cm.

In order to evaluate the amount of frosting needed, we have to evaluate the surface area of the cake. The surface area of the cake is the summation of the areas of all its sides.
Here the area of each side is equivalent to its length multiplied by its width. Then the area of the given top is equivalent to its length multiplied by its width.

Then the evaluated surface area of the cake is
2 × (length × height + width × height) + length × width
= 2 × (600 cm × 180 cm + 400 cm × 180 cm) + 600 cm × 400 cm
= 2 × (108000 cm² + 72000 cm²) + 240000 cm²
= 2 × 180000 cm² + 240000 cm²
= 600000 cm²
Hence, one liter of green frosting covers about 1200 cm².
600000 cm² / 1200 cm² per liter = 500 liters

Therefore, Barbara and her assistants needed 500 liters of frosting for their dieter's nightmare.

energy?

Answers

The velocity of the bowling ball is approximately 20.104 meters per second.

What is velocity?

The pace at which an object's position changes in relation to a frame of reference and time is what is meant by velocity.

The formula given is used to calculate the velocity of a moving object in meters per second, given the object's mass in kilograms and its kinetic energy in joules. The formula is:

V = √(2E/m)

where V is the velocity, E is the kinetic energy, and m is the mass of the object.

To use this formula to find the velocity of the bowling ball, we need to substitute the given values into the formula. The mass of the bowling ball is 5.5 kilograms, and the kinetic energy is 2223 joules. Substituting these values, we get:

V = √(2 × 2223 J / 5.5 kg)

Now, we can simplify the equation:

V = √(404.1818)

Using a calculator, we can find the square root of 404.1818:

V = 20.104 m/s (rounded to three decimal places)

Therefore, the velocity of the bowling ball is approximately 20.104 meters per second.

This formula is useful for calculating the velocity of a moving object when the mass and kinetic energy of the object are known. It can be used in a variety of situations, such as in physics experiments, engineering design, or in understanding the motion of objects in sports.

Albert and Makayla are each renting a car for one day. Albert’s rental agreement states that the car costs $35 per day and $0. 15 per mile driven. Makayla’s agreement states that the car she is renting costs $45 per day and $0. 10 per mile driven. Write an equation to determine the number of miles, m, Albert and Makayla drive if they spend the same amount of money on their rentals

Answers

To determine the number of miles, m, Albert and Makayla drive if they spend the same amount of money on their rentals, we can write an equation using the given information:

Albert's cost = $35 per day + $0.15 per mile driven
Makayla's cost = $45 per day + $0.10 per mile driven

Since they spend the same amount of money, we can set the costs equal to each other:

35 + 0.15m = 45 + 0.10m

Now, we need to solve the equation form, the number of miles driven:

1. Subtract 0.10m from both sides:
35 + 0.05m = 45

2. Subtract 35 from both sides:
0.05m = 10

3. Divide both sides by 0.05:
m = 200

So, if Albert and Makayla spend the same amount of money on their rentals, they both drive 200 miles.
