The value of the investment after 3.5 years is approximately $2530.67.

The principal amount refers to the initial amount of money borrowed or invested, excluding any interest or additional fees. For example, if someone takes out a loan for $10,000, the principal amount is $10,000, and this is the amount that must be repaid to the lender, not including any interest that may accrue over time. Similarly, if someone invests $5,000 in a savings account, the principal amount is $5,000, and any interest earned on that amount will be calculated based on the principal amount. The principal amount is an important concept in finance and investing, as it determines the starting point for calculating interest, returns, and other financial transactions.

The formula for compound interest is:

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

Where:

A = the final amount

P = the principal amount (initial investment)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time (in years)

In this case, we have:

P = 2000

r = 0.04 (4% as a decimal)

n = 12 (compounded monthly, so 12 times per year)

t = 3.5 (3.5 years)

Plugging these values into the formula, we get:

[tex]A= 2000(\frac{1+0.04}{12})^{12*3.5}[/tex]

A = 2000(1.00333333)⁴²

A ≈ 2530.67

Therefore, the value of the investment after 3.5 years is approximately $2530.67.

what is equation ?

An equation is a mathematical statement that asserts that two expressions are equal. In other words, an equation says that one expression on the left side of the equals sign is the same as the expression on the right side of the equals sign. An equation typically includes variables

In the given question,

To determine the equation of the line passing through the points (0,-3) and (2,0), we can use the slope-intercept form of a linear equation:

y = mx + b

where m is the slope and b is the y-intercept.

The slope of the line can be found using the formula:

m = (y₂ - y₁) / (x₂ - x₁)

where (x₁, y₁) = (0,-3) and (x₂, y₂) = (2,0)

m = (0 - (-3)) / (2 - 0) = 3/2

So the equation of the line is:

y = (3/2)x - 3

Now we can check which ordered pair is a solution to this equation by plugging in the x and y values into the equation and seeing if it holds true.

A. (0,-3)

y = (3/2)x - 3

-3 = (3/2)(0) - 3

-3 = -3

This is true, so (0,-3) is a solution.

B. (2,0)

y = (3/2)x - 3

0 = (3/2)(2) - 3

0 = 0

This is true, so (2,0) is a solution.

C. (2,2)

y = (3/2)x - 3

2 = (3/2)(2) - 3

2 = 0

This is false, so (2,2) is not a solution.

D. (-3,0)

y = (3/2)x - 3

0 = (3/2)(-3) - 3

0 = -9/2

This is false, so (-3,0) is not a solution.

Therefore, the solutions to the equation represented by the graph are A. (0,-3) and B. (2,0).

Therefore, the surface area of the given triangular prism is approximately 126.56 square units.

Surface area is a measure of the total area that the surface of a three-dimensional object occupies. It is the sum of the areas of all the faces or surfaces of an object. Surface area is usually expressed in square units, such as square inches, square centimeters, or square meters, depending on the unit system being used.

For example, if you have a cube with side length "s", its surface area can be calculated by finding the area of each face and adding them together. Since a cube has six square faces of equal size, the formula for its surface area would be:

Surface Area of Cube = 6s²

by the question.

To find the surface area of a triangular prism, we need to calculate the area of all its faces and then add them together.

First, let's find the area of the two triangular bases. Each base is a right triangle with base 5, height 4, and hypotenuse 7. We can use the Pythagorean theorem to calculate the height of the triangle:

[tex]4^2 + (5/2)^2 = h^2[/tex]

[tex]16 + 6.25 = h^2[/tex]

[tex]22.25 = h^2[/tex]

[tex]h = \sqrt(22.25)[/tex]= 4.71

So, the area of each base is:

[tex]A = 1/2 * base * height = 1/2 * 5 * 4.71 = 11.78[/tex]

Next, we need to find the area of the three rectangular faces. The two congruent rectangular faces have dimensions of 5 by 6, and the remaining rectangular face has dimensions of 7 by 6. The area of each rectangular face is simply the product of its dimensions:

[tex]A1 = 5 * 6 = 30[/tex]

[tex]A2 = 5 * 6 = 30[/tex]

[tex]A3 = 7 * 6 = 42[/tex]

Finally, we can calculate the total surface area of the prism by adding up the areas of all five faces:

[tex]Total surface area = 2A(base) + A1 + A2 + A3[/tex]

[tex]Total surface area = 2(11.78) + 30 + 30 + 42[/tex]

[tex]Total surface area =126.56[/tex]

Answer:3,575 lbs, or 45% less

Step-by-step explanation:

Unit for garbage collected: pounds (lbs)

Unit for time: month (mo)

Let's use "t" as the variable for time (in months).

Expression for the amount of garbage collected:

For the initial cleanup: 6,500 lbs

For subsequent cleanups: 45% less garbage collected each month, which means they collect 55% of the previous month's garbage. So, the expression for the amount of garbage collected each month (starting from the second month) would be:

0.55^(t-1) * 6,500 lbs

where "t" represents the number of months after the initial cleanup.

Note that for t=1 (i.e., the first subsequent cleanup), the expression evaluates to 0.55^(1-1) * 6,500 lbs = 6,500 * 1 = 6,500 lbs, which is consistent with the initial cleanup. For t=2, the expression evaluates to 0.55^(2-1) * 6,500 lbs ≈ 3,575 lbs, which is 45% less than the amount collected in the first subsequent cleanup.

A ratio is a couple of numbers that are looked at. Part-to-part, part-to-entire, and entire-to-part correlations are examples of ratios. Units could conceivably be remembered for the ratios.

A two-layered plane framed by the crossing point of an upward line which is known as the y-axis and a horizontal line called the x-axis is known as a coordinate plane. These are a bunch of opposite lines that converge at nothing, which is known as the beginning. The axes partition the coordinate plane into four segments, every one of which is alluded to as a quadrant.

Requested matches are utilized to chart and find focuses on a coordinate plane. The arranged matches are dependably in the (x, y) structure where the primary number is the x-coordinate and the subsequent number is the y-coordinate. The principal coordinate lets you know how far to move along the x-axis, and the subsequent coordinate lets you know how far to go up or down the y-axis.

Step-by-step explanation:

The length of the midsegment of the trapezoid is 38.5. The midsegment is the line segment that connects the midpoints of the two parallel sides of the trapezoid. It divides the trapezoid into two congruent triangles.

To find the length of the midsegment of the trapezoid, we need to first find the midpoint of the two parallel sides of the trapezoid. To do so, we need to use the midpoint formula, which is (x1 + x2) ÷ 2, (y1 + y2) ÷ 2, where (x1, y1) and (x2, y2) are the coordinates of the two points.

For example, if the coordinates of the two points are (1,2) and (5,7), then the midpoint of the two points will be (1+5) ÷ 2, (2+7) ÷ 2 = (6, 4.5).

Once we have the coordinates of the two midpoints, we can use the distance formula to find the length of the midsegment. The distance formula is √((x2-x1)² + (y2-y1)²).

So if the coordinates of the two midpoints are (3,6) and (9,2), then the length of the midsegment will be √((9-3)² +(2-6)²) = √(36+16) = √52 = 38.5.

The percent decrease in the number of people who went to the local swimming pool over four weeks, starting with a record high of 1,060 people in the first week, was 20%.

To find the percent decrease in the number of people who went to the pool over the four weeks, we need to first find the total number of people who went to the pool over the four weeks and then calculate the percentage decrease from the first week to the fourth week.

Number of people in the first week = 1,060

Number of people in the second week = 1,060 - 110 = 950

Number of people in the third week = 950 + 130 = 1,080

Number of people in the fourth week = 1,080 - 232 = 848

Total number of people over the four weeks = 1,060 + 950 + 1,080 + 848 = 3,938

Percentage decrease in the number of people who went to the pool over the four weeks = ((1,060 - 848)/1,060) * 100% = 20%

The value of B using Sine law is approximately 41.7 degrees.

To use the sine law to find angle B, we need to have either the length of side b or the sine of angle B. However, we can use the sine law to set up an equation involving sine B and then solve for it.

the sine law states:

a/sin A = b/sin B = c/sin C

where a, b, and c are the lengths of the sides of a triangle, and A, B, and C are the opposite angles.

In this case, we are given a = 28.82 ft, c = 47.74 ft, and we want to find B. We can set up the following equation using the sine law:

a/sin A = c/sin C

Substituting the given values:

28.82/sin A = 47.74/sin C

Now, we need to find sin A and sin C. Since the angles in a triangle add up to 180 degrees, we have:

A + B + C = 180

We know that A and C are the angles opposite to sides a and c, respectively, so we can use the sine ratio to express them in terms of a and c:

sin A = a/cos B

sin C = c/cos B

Substituting these expressions into the equation above, we get:

28.82/(a/cos B) = 47.74/(c/cos B)

Simplifying and solving for cos B, we get:

cos B = (28.82 * c) / (a * 47.74)

Now that we know cos B, we can use the identity sin^2 B + cos^2 B = 1 to find sin B:

sin B = sqrt(1 - cos^2 B)

Substituting the given values, we get:

sin B = sqrt(1 - ((28.82 * 47.74) / (a * c))^2)

Calculating this expression gives:

sin B = 0.667

Therefore, angle B is:

B = sin^-1(0.667) = 41.7 degrees (rounded to one decimal place)

So, angle B is approximately 41.7 degrees.

The resultant substraction value of the sum of three hundredths and 256 tenths from 41435 hundredths is equals to the 388.72.

Subtraction is one of the four arithmetic operations along with addition, multiplication and division. Subtraction is an operation representing the removal of an object from a collection. This is indicated by the symbol '-'. For example, there are 5 − 2 books meaning 5 books with 2 taken away, resulting in a total of 3 books. We have sum of three hundredths and 256 tenths. First, 3 hundredths means 3 out of 100, which can be denoted as = 3/100 = 0.03. Similarly, 256 tenth means 256/10 = 25.6. So, the sum of three hundredths and 256 tenths = 25.60 + 0.03 = 25.63 and 41435 hundredths = 414.35. Now, substract 25.63 from 414.35

The proportion of students who took ACT and scored between 18 and 28, P(18 < X < 28) is 0.607.

The proportion of students who took ACT and scored between 18 and 28, P(18 < X < 28) is given by the formula:

P(18 < X < 28) = P(Z < (28 - 21)/5.5) - P(Z < (18 - 21)/5.5)

We can then calculate the z-scores for the lower and upper bounds of the range as follows:

Z1 = (28 - 21)/5.5 = 1.27Z2 = (18 - 21)/5.5 = -0.55

Using a z-table or calculator, we can find the probabilities associated with these z-scores:

P(Z < 1.27) = 0.898P(Z < -0.55) = 0.291

Therefore,P(18 < X < 28) = P(Z < 1.27) - P(Z < -0.55) = 0.898 - 0.291 = 0.607

The answer is  option (d)  "The volume of  sphere can be interpreted as  product of  radius cubed and  constant factor."

The volume of a three-dimensional object refers to the amount of space that it occupies. More specifically, it is a measure of the amount of enclosed space within a solid shape, like a cube, sphere, cylinder, or any other three-dimensional object. The formula for calculating volume of  solid depends on its shape. The formula for the volume of a sphere, as mentioned in the previous question, is V=4/3πr³, where r is the radius of the sphere.

Volumes are typically measured in cubic units, like cubic meters, cubic centimeters, or cubic feet.

The statement that is true is: "The volume of sphere can be interpreted as  product of radius cubed and  constant factor."

The formula for the volume of a sphere, V=4/3πr³, shows that the volume is proportional to the cube of the radius. This means that if the radius of a sphere is doubled, the volume will increase by a factor of 2³=8. Similarly, if the radius is tripled, the volume will increase by a factor of 3³=27.

The constant factor in the formula, 4/3π, is a fixed value that applies to all spheres, regardless of their size. It is a constant because it does not depend on the radius of the sphere.

Therefore, we can interpret the formula for the volume of a sphere as the product of the radius cubed and a constant factor.

The complement of set Q {-4, -3, -2} if the universal set is P {-5, -4, -3, -2, -1} is defined by:

¬Q = {-5, -1}

If we have a set A defined in an universal set U, we define the complement of A as all the elements of U that are not elements of A.

In this case we have the sets:

P = {-5, -4, -3, -2, -1}

Q = {-4, -3, -2}

Here we want to find the complement of Q in P, so P is the universal set for this problem.

The elements of P that are not elements of Q are:

{-5, -1}

So that is the complement that we are looking for.
