Answers

Answer 1

Area of sector = 161.1 square inches

Activity 1:

The radius of the pizza is half of its diameter, which is 16/2 = 8 inches.

The central angle of the sector is 80%, which is 0.8 times 360 degrees = 288 degrees.

To find the area of the sector, we use the formula:

Area of sector = (central angle / 360) x πr^2

Area of sector = (288 / 360) x π x 8^2

Area of sector = (0.8) x π x 64

Area of sector = 161.1 square inches (rounded to the nearest tenth)

Activity 2:

The unit of measurement for the area of the sector is square inches (in²).

A family with travel 475 miles on the Road trip which inequality can be used to find all possible values of T the time it would take to reach their destination if they travel in an average speed of at least in miles per hour

Answers

The inequality that can be used to find all possible values of T, the time it would take to reach their destination if they travel at an average speed of at least "r" miles per hour, can be expressed as:

T ≤ 475 / r

This inequality states that the time taken (T) should be less than or equal to the distance traveled (475 miles) divided by the average speed (r miles per hour). By dividing the total distance by the average speed, we obtain the maximum time it would take to reach the destination. Any time less than or equal to this value would satisfy the condition of traveling at an average speed of at least "r" miles per hour.

a) Find the general solution of the differential equation dy 2.cy dar 22 +1 3 b) Find the particular solution that satisfies y(0) 2

Answers

The particular solution is [tex]y(t) = (1/2c) (t^2/2 + t/2 + 1/2c) + (2 - 1/(4c))e^(-2ct)[/tex].

[tex]dy/dt + 2cy = t^2 + 1[/tex]

To find the general solution of this differential equation, we can start by finding the integrating factor, which is given by:

I(t) = e^(∫2c dt) = [tex]e^(2ct)[/tex]

Next, we can multiply both sides of the differential equation by the integrating factor I(t):

[tex]e^(2ct) dy/dt + 2ce^(2ct) y = (t^2 + 1) e^(2ct)[/tex]

We can now recognize the left-hand side as the product rule of the derivative of the product of y and I(t):

[tex](d/dt)(y e^(2ct)) = (t^2 + 1) e^(2ct)[/tex]

Integrating both sides with respect to t gives:

[tex]y e^(2ct) = ∫(t^2 + 1) e^(2ct) dt + C[/tex]

The integral on the right-hand side can be solved using integration by parts, and we get:

∫([tex]t^2[/tex] + 1) [tex]e^(2ct) dt = (1/2c) e^(2ct) (t^2/2 + t/2 + 1/2c) + K[/tex]

where K is an arbitrary constant of integration.

Substituting this expression back into the previous equation, we get:

[tex]y e^(2ct) = (1/2c) e^(2ct) (t^2/2 + t/2 + 1/2c) + K[/tex]

Dividing both sides by e^(2ct), we obtain the general solution:

[tex]y(t) = (1/2c) (t^2/2 + t/2 + 1/2c) + Ke^(-2ct)[/tex]

where K is an arbitrary constant.

To find the particular solution that satisfies y(0) = 2, we can substitute t = 0 and y(0) = 2 into the general solution and solve for K:

[tex]y(0) = (1/2c) (0^2/2 + 0/2 + 1/2c) + Ke^(0)[/tex]

2 = 1/(4c) + K

Solving for K, we get:

K = 2 - 1/(4c)

Substituting this value of K back into the general solution, we get the particular solution:

[tex]y(t) = (1/2c) (t^2/2 + t/2 + 1/2c) + (2 - 1/(4c))e^(-2ct)[/tex]

a driveway consists of two rectangles one rectangle is 80 ft long and 15 ft wide the other is 30 ft long and 30 ft wide what is the area of the driveway ​

Answers

Answer: 2100 square feet

Step-by-step explanation:

To solve this question we must add the areas of the two rectangles.

area = length x width

Rect 1:

a = lw

  = 80 x 15 = 1200 square feet

Rect 2:

a = lw

  = 30 x 30 = 900 square feet

so in total, the driveway is 1200 + 900 = 2100 square feet

Answer:

To find the area of the driveway, we need to find the area of both rectangles and add them together.

The area of the first rectangle is:

80 ft x 15 ft = 1200 sq ft

The area of the second rectangle is:

30 ft x 30 ft = 900 sq ft

To find the total area of the driveway, we add the two areas together:

1200 sq ft + 900 sq ft = 2100 sq ft

Therefore, the area of the driveway is 2100 square feet.

Answers

To maximize the total weight of bass in the lake, we should stock 3000 smallmouth bass and 4666.67 largemouth bass

To maximize the total weight of bass in the lake, we need to find the optimal values of and that will maximize the total weight of the fish.

Let's start by writing an expression for the total weight of the fish in the lake:

Total weight = (weight of a single smallmouth bass) × (number of smallmouth bass) + (weight of a single largemouth bass) × (number of largemouth bass)

Substituting the given expressions for the weight of a single smallmouth bass and largemouth bass, we get:

Total weight = (0.5 + 0.1) × × + (1.2 + 0.2) ×

Simplifying this expression, we get:

Total weight = (0.6) × × + (1.4) ×

To find the optimal values of and that maximize the total weight, we can take the partial derivatives of this expression with respect to and and set them equal to zero:

[tex]∂ \frac{(Total weight)}{∂} = 0.6-0.0002=0[/tex]

[tex]∂ \frac{(Total weight)}{∂} = 1.4-0.0003=0[/tex]

Solving these equations simultaneously, we get:

= 3000

= 4666.67

Therefore, to maximize the total weight of bass in the lake, we should stock 3000 smallmouth bass and 4666.67 largemouth bass.

Kyla has a concrete patio in the shape of a semi-circle. What is the area of the patio? Use 3. 14 for π. It’s s i circle and is 6. 75 ft and in squared

Answers

The area of the semi-circle patio is approximately 17.91 square feet.

To find the area of the semi-circle patio, we need to use the formula for the area of a circle, which is A = πr^2, where π is 3.14 and r is the radius of the circle.

However, since we only have a semi-circle, we need to divide the result by 2 to get the area of the half-circle.

In this case, the radius of the semi-circle is half of the diameter, which is given as 6.75 feet. So, the radius is 6.75/2 = 3.375 feet.

Now, we can plug this value into the formula:

A = (π)(3.375)^2 / 2

A = (3.14)(11.390625) / 2

A = 35.81765625 / 2

A = 17.908828125 square feet

please help me because i really need with this question <3

Answers

The pool has approximately 258.2 square feet of plastic material. Rounded to the nearest tenth, the answer is 258.2 square feet.+

To calculate the surface area of the pool that is lined with plastic material, we need to find the area of the curved part and the area of the top and bottom circles.

First, let's find the radius of the pool, which is half of the diameter:

radius = 11 feet / 2 = 5.5 feet

The curved part of the pool is a cylinder with a height of 2 feet and a circumference of [tex]2 * π *radius:[/tex]

curved area = height * circumference

[tex]curved area = 2 feet * 2 * 3.14 * 5.5 feet[/tex]

[tex]curved area = 68.2 square feet[/tex]

The top and bottom of the pool are two circles with a radius of 5.5 feet:

circle area = π * radius²

[tex]circle area = 3.14 * 5.5 square feet[/tex]

[tex]circle area = 95.0 square feet[/tex]

To find the total surface area of the pool that is lined with plastic material, we add the area of the curved part and the area of the top and bottom circles:

Total area = curved area + 2 * circle area

Total area = 68.2 square feet + 2 * 95.0 square feet

Total area = 258.2 square feet

Answers

The value of (f + g)(−3) given the functions f(x) = x² − 6x − 4 and g(x) = 5x + 3 is 11.

To find (f + g)(-3), we first need to add the functions f(x) and g(x) together, and then evaluate the resulting function at x = -3.

f(x) = x² - 6x - 4
g(x) = 5x + 3

Now, let's add f(x) and g(x):

(f + g)(x) = (x² - 6x - 4) + (5x + 3) = x² - x - 1

Now that we have the combined function, we can evaluate it at x = -3:

Find the slope of the line through points 6,3 and 12,7

Answers

The slope of the line through points (6,3) and (12,7) is 2/3.

To find the slope of a line, we use the formula:

Slope = (y2 - y1) / (x2 - x1)

In this case, we have two points: (6, 3) and (12, 7). We can label them as follows:

x1 = 6
y1 = 3
x2 = 12
y2 = 7

Now we can plug these values into the formula:

Slope = (y2 - y1) / (x2 - x1)
Slope = (7 - 3) / (12 - 6)
Slope = 4 / 6
Slope = 2/3

Therefore, the slope of the line through the points (6, 3) and (12, 7) is 2/3.

The slope of a line tells us how steep it is. A positive slope means the line goes up as you move from left to right, while a negative slope means the line goes down. In this case, since the slope is positive (2/3), we know that the line goes up as we move from left to right.

The slope also tells us how much the y-value changes for every one unit of x-value. In this case, for every one unit we move to the right, the y-value goes up by 2/3.

Part B: Give an example of an undefined term and how it relates to a circle. (5 points)

Answers

Part A:

The definition provided for a circle is actually correct. However, if we change the definition slightly to say that a circle is the set of all points in a plane that are the same distance from a given point, we can find an example that contradicts it.

For instance, consider a cone in three-dimensional space. If we take a cross-section of the cone that is parallel to the base, we get a circle. However, this circle is not the set of all points that are the same distance from one given point, but rather from the axis of the cone.

To make the definition more accurate, we need to specify that the circle exists in a plane.

Part B:

An example of an undefined term related to a circle is the term "point." A circle is defined as the set of all points that are the same distance from a given point, but the term "point" is not defined within this definition.

A point is typically defined as a location in space that has no size or shape. In the context of a circle, a point can be thought of as any location on the circumference of the circle. However, it is important to note that the definition of a point is not dependent on the definition of a circle, and vice versa.

25 acres of a forest is covered by coniferous trees. The remaining are shrubs and bushes which constitutes 42% of the total area of the forest. What is the total area of under the forest?

Answers

Therefore, the total area of the forest is approximately 43.10 acres.

What is area?

Area is the measure of the size of a two-dimensional surface or region. It is typically measured in square units, such as square meters (m²) or square feet (ft²). The area of a shape can be calculated by multiplying the length and the width of the shape. Different shapes have different formulas for calculating their area, such as the formula for the area of a rectangle, which is length x width, or the formula for the area of a circle, which is πr², where r is the radius of the circle and π is a mathematical constant approximately equal to 3.14159.

Here,

Let's call the total area of the forest "T".

We know that 25 acres of the forest is covered by coniferous trees. Therefore, the remaining area of the forest is:

T - 25

We also know that the shrubs and bushes constitute 42% of the total area of the forest. This means that:

0.42 x T = area covered by shrubs and bushes

Putting it all together, we can set up the following equation:

T = 25 + (0.42 x T)

Simplifying, we can solve for T:

0.58 x T = 25

T = 25 / 0.58

ANALYZE In Europe, fuel economy is measured in liters per 100 kilometers. On a 2500 km road trip a car used 150 liters of fuel. The car used an average of how many liters per 100 km?

Answers

To find out the car's average fuel consumption in liters per 100 kilometers, we need to use the following formula:

Fuel consumption (liters per 100 km) = (Total fuel used / Total distance traveled) x 100

Using the information given, we know that the car traveled 2500 km and used 150 liters of fuel. Plugging these values into the formula, we get:

Fuel consumption (liters per 100 km) = (150 / 2500) x 100 = 6

Therefore, the car used an average of 6 liters of fuel per 100 kilometers on its 2500 km road trip.

It is important to note that fuel economy is an important factor in Europe, where fuel prices are generally higher than in other parts of the world.

By measuring fuel consumption in liters per 100 kilometers, European consumers can easily compare the fuel efficiency of different vehicles and make more informed purchasing decisions.

Additionally, analyzing fuel consumption data can help drivers identify ways to improve their fuel efficiency, such as reducing their speed, maintaining proper tire pressure, and avoiding excessive idling.

All-star trinkets estimates its monthly profits using a quadratic function. the table shows the total profit as a function of the number of trinkets produced. which function can be used to model the monthly profit for x trinkets produced? f(x) = –4(x – 50)(x – 250) f(x) = (x – 50)(x – 250) f(x) = 28(x 50)(x 250) f(x) = (x 50)(x 250)

Answers

The function used to model the monthly profit for x trinkets produced are f(x) = -4(x - 50)(x - 250). The maximum profit occurs when 150 trinkets are produced.

The quadratic function that can be used to model the monthly profit for x trinkets produced is:

f(x) = -4(x - 50)(x - 250)

This is because the function is in the form of a quadratic equation, which is y = ax² + bx + c. In this case, a = -4, b = 1200, and c = 0. When we expand and simplify the equation, we get:

f(x) = -4x² + 1200x

This equation represents a parabola with a maximum value at x = 150. Therefore, the maximum profit occurs when 150 trinkets are produced.

The other answer choices are not correct because they are not quadratic functions. For example, f(x) = (x - 50)(x - 250) is a product of linear factors, and f(x) = 28(x - 50)(x + 250) and f(x) = (x + 50)(x + 250) have a coefficient of x² that is not equal to -4.

the operation manager at a tire manufacturing company believes that the mean mileage of a tire is 37,014 miles, with a standard deviation of 4617 miles. what is the probability that the sample mean would differ from the population mean by less than 221 miles in a sample of 56 tires if the manager is correct? round your answer to four decimal places.

Answers

Probability or p-vale that the sample mean would differ from the population mean by less than 221 miles in a sample of 56 tires is equals to zero if the manager is correct.

We have data of an operation manager at a tire manufacturing company.

Mean mileage of a tire, [tex] \mu[/tex]

= 37,014 miles

standard deviation, [tex] \sigma[/tex]

= 4617 miles.

Sample size, n = 56

We have to determine the probability that the sample mean would differ from the population mean by less than 221 miles. Using Z-score formula in normal distribution, [tex]\small z= \frac{ \bar x-\mu }{\frac{\sigma }{\sqrt{n}}},[/tex]

Plugging all known values in above formula, [tex]z = \frac{ 221 - 37,014} {\frac{4617}{ \sqrt{56}}}[/tex]

= 59.634

[tex]P( \bar x < 221) = P ( \frac{ \bar x-\mu }{\frac{\sigma }{\sqrt{n}}} < \frac{ 221 - 37,014} {\frac{4617}{ \sqrt{56}}}) \\ [/tex]

=> P ( z < 59.63) = P( \bar x < 221)

Using the Z-distribution table, probability value is equals to 0. Hence, required probability is zero.

Chord eg measures 8 inches and the distance from the center of j to the chord is 3 inches

Answers

The length of chord segment EG = 6 inches and the length of FG = √23 inches.

Given, chord EG = 8 inches and the distance from the center of J to the chord is 3 inches.

We can draw a diagram as follows:

              J

            /   \

           /     \

          /       \

         /         \

        E-----------G

              |

              |

              |

              |

              |

              F

Here, OJ is perpendicular to chord EG at point F.

As per the theorem, the length of the perpendicular from the center of the circle to a chord is half the length of the diameter intersecting the chord.

So, we can find the length of the diameter intersecting chord EG and then use it to find the radius of the circle.

Length of chord EG = 8 inches

Length of OJ = 3 inches

Using Pythagorean theorem in right triangle OFG, we get:

OG² = OF² + FG²

Let x be the length of FG

We know that OF = OJ = 3 inches

OG = radius of the circle

So, we have:

radius of circle = OG = √(OF² + FG²) = √(3² + x²)

The diameter of the circle = 2(radius) = 2√(3² + x²)

Now, using the theorem mentioned above, we can say:

Length of perpendicular from the center of the circle to chord EG = OF = 3 inches

Length of diameter intersecting chord EG = 2√(3² + x²)

So, we get:

Length of chord segment EG = 2 * length of perpendicular

                            = 2 * 3 inches

                           = 6 inches

Now, we know that the chord segment EG divides the diameter intersecting it into two equal parts.

So, we have:

Length of one part of the diameter = (2√(3² + x²))/2 = √(3² + x²)

Using Pythagorean theorem in right triangle OJF, we get:

OJ² + JF² = OF²

3² + JF² = 8²

JF² = 8² - 3² = 55

JF = √55

Using Pythagorean theorem in right triangle JFG, we get:

JG² + FG² = JF²

(√(3² + x²))² + x² = 55

9 + x² + x² = 55

2x² = 46

x² = 23

x = √23

Therefore, the length of chord segment EG = 6 inches and the length of FG = √23 inches.

Find the value(s) of k for which u(x,t) = e¯³ᵗsin(kt) satisfies the equation uₜ = 4uxx

Answers

The two values of k that satisfy the given equation are approximately 0.1449/t and 1.096/t.

We have the partial differential equation uₜ = 4uₓₓ. Substituting u(x,t) = e¯³ᵗsin(kt) into this equation, we get:

uₜ = e¯³ᵗ(k cos(kt) - 3k sin(kt))

uₓₓ = e¯³ᵗ(-k² sin(kt))

Now, we can compute uₓₓ and uₜ and substitute these expressions back into the partial differential equation:

uₜ = 4uₓₓ

e¯³ᵗ(k cos(kt) - 3k sin(kt)) = -4k²e¯³ᵗ sin(kt)

Dividing both sides by e¯³ᵗ and sin(kt), we get:

k cos(kt) - 3k sin(kt) = -4k²

Dividing both sides by k and simplifying, we get:

tan(kt) - 1 = -4k

Letting z = kt, we can write this equation as:

tan(z) = 4z + 1

We can graph y = tan(z) and y = 4z + 1 and find their intersection points to find the values of z (and therefore k) that satisfy the equation. The first intersection point is approximately z = 0.1449, which corresponds to k ≈ 0.1449/t. The second intersection point is approximately z = 1.096, which corresponds to k ≈ 1.096/t. Therefore, the two values of k that satisfy the given equation are approximately 0.1449/t and 1.096/t.

Penny decided to travel to Palawan. The airplane flew at an average rate of 300 miles per hour and covered 1500 miles. How long will the flight will take? *

A. 3 hours

B. 4 hours

C. 5 hours

D. 6 hours

Answers

The time it will take the flight is C) 5 hours.

To solve this problem, we can use the formula: distance = rate x time. In this case, we know that the distance is 1500 miles and the rate (or speed) is 300 miles per hour. We can rearrange the formula to solve for time: time = distance / rate. Plugging in the values we have, we get:

time = 1500 miles / 300 miles per hour
time = 5 hours

Therefore, the correct answer is C. It will take Penny 5 hours to fly from her starting point to Palawan at an average speed of 300 miles per hour. This calculation assumes that the plane maintains a constant speed throughout the entire flight, which may not be the case due to factors such as wind and turbulence.

The value of x is  17.5 when the given diagonals of square ABCD points intersect at M and the measure 0f <MAD = 6x-15.

The diagonals are perpendicular bisectors of each other in a square and they intersect at the center of the square. By using diagonals we can divide the square into four congruent right triangles and assume that diagonals are all right angles (90 degrees).

let us consider the angle MAD as one of these angles. we can find the value of x by using the equation

6x - 15 = 90

6x = 105

x = 105/6

Please help me answer this question for my Humanites class it is based on a selected artwork I choose The Farm by Joan Miro Overview: Mir moved from Barcelona to Paris in 1920, determined to participate in the artistic vanguard of the French capital. Nevertheless, he remained deeply attached to his native Catalonia, and returned each summer to his family's farm in the village of Montroig. In 1921, he determined to make a painting of this farm, a painting that he came to regard as one of the key works in his career.The Farm represents a brilliant amalgamation of an intense, even primitive realism with the formal vocabulary of cubism. The painting is a compendium of separate details, each carefully observed and precisely described. This detailed realism, however, is matched by a tendency to simplify forms into abstract, geometric shapes. Moreover, space in The Farm is defined by a ground plane that tilts sharply upward, while individual forms are similarly tilted, so that they sit silhouetted, parallel to the picture plane.By the mid-1920s, Mir had abandoned the realist manner of The Farm and had created a surrealist style of automatism and abstraction. Elements from The Farm continued to appear in his work, however, and the intensity of vision found in this painting remained a standard for all of his later art.Question:How is the selection classified in the Humanities?
