Step-by-step explanation:

Let the distance between police station and the fire station be x.

According to question we have:

It can be expressed as:

Solve the equation for x:

Correct choice is C

Simplifying this equation gives the correct option as C. V(w) = 24w² - 512w + 2048.

To simplify an equation, we need to perform various operations to reduce it to a simpler or more manageable form. The specific steps for simplification depend on the equation and the desired form.

Here is the solution for the two questions:

Question 1:

The given problem can be solved by using the formula:

Revenue = number of trees * yield per tree * price per bushel

So, the maximum revenue will occur at a point where the derivative of the above formula will be equal to 0.

Then we can find the number of trees that need to be planted.

Thus, the correct option is B.27 trees per acre, maximum revenue of $7.480

Question 2:

The given diagram will look like the following:

The original length of the rectangle will be 3w and the original width will be w. Then, the side of each square that is cut out will be 8 inches. Thus, the width of the box will be w - 2 * 8 and the length will be 3w - 2 * 8.

Therefore, the volume of the box is given by:

V(w) = 8 * (w - 16) * (3w - 16)

Simplifying this equation gives the correct option as C.

V(w) = 24w² - 512w + 2048.

The ROI per unit for Jaymes Corporation's rotors is $200.

To calculate the ROI per unit, we need to divide the total return on investment by the number of units produced. In this case, the company has invested $6,000,000 to produce 30,000 rotors.

ROI per unit = Total ROI / Number of units produced

Total ROI = $6,000,000

Number of units produced = 30,000

ROI per unit = $6,000,000 / 30,000 = $200

Therefore, the ROI per unit for Jaymes Corporation's rotors is $200. This means that for every rotor produced, the company expects to generate a return of $200.

The distance from the point to the given plane is 16/7 units.

To find the distance from a point to a given plane, we can use the formula:

distance = |ax + by + cz - d| / √(a^2 + b^2 + c^2)

where (x, y, z) are the coordinates of the point, and a, b, c, and d are the coefficients of the plane equation.

In this case, the point is (1, -3, 4) and the plane equation is 3x + 2y + 6z = 5.

Let's plug in the values:

distance = |(3*1) + (2*(-3)) + (6*4) - 5| / √(3^2 + 2^2 + 6^2)

Simplifying:

distance = |3 - 6 + 24 - 5| / √(9 + 4 + 36)
distance = |16| / √49
distance = 16 / 7

Therefore, the distance from the point (1, -3, 4) to the plane 3x + 2y + 6z = 5 is 16/7 units.

According to the question There are 108 ways to color the bottom truncated tetrathingy using the same four colors as the top truncated tetrathingy, ensuring that no two chunks of the same color are touching.

To solve this problem, we can consider each chunk of the bottom truncated tetrathingy individually and determine the number of color options for each chunk while ensuring that no two adjacent chunks have the same color.

Since we have four colors available, let's label them as A, B, C, and D.

Let's start with the first chunk. We have four color options for it.

For the second chunk, we have three color options available. We cannot use the color that was used for the adjacent chunk, so we have three choices.

For the third chunk, we again have three color options available, excluding the color used for the second chunk.

Lastly, for the fourth and final chunk, we have three color options available, excluding the color used for the third chunk.

Since each chunk's color choice is independent of the others, we can multiply the number of color options for each chunk together to find the total number of ways to color the bottom truncated tetrathingy:

Number of ways = 4 * 3 * 3 * 3 = 108 ways

Therefore, there are 108 ways to color the bottom truncated tetrathingy using the same four colors as the top truncated tetrathingy, ensuring that no two chunks of the same color are touching.

The volume of the cone with a height of 13 times the radius of the original cone can be expressed as V = (1/3)πr^2(13r), where r is the radius.


The volume of a cone is given by the formula V = (1/3)πr^2h, where r is the radius and h is the height. In this case, the height of the new cone is 13 times the radius of the original cone.

Therefore, we can replace the height, h, with 13r, where r is the radius. Substituting this into the volume formula, we get V = (1/3)πr^2(13r).

This expression represents the volume of the cone with a height of 13 times the radius of the original cone. By plugging in the value of the radius, we can calculate the actual volume of the cone.

For a polygon which is composed of three rectangles and dimensions are 4 ft× 2ft, 4 ft× 3 ft , 8 ft × 1.2ft. Area of polygon is 29.6 ft².

In geometry, a polygon is defined as the flat or plane surface, two-dimensional closed shape of boundaries. The sides of a polygon are also known as its edges. The points where two sides meet are called vertices (or corners) of a polygon. We have a polygon is composed of three rectangles.

The dimensions of rectangles are the following, 4 ft× 2ft, 4 ft× 3 ft , 8 ft × 1.2ft. We have to determine the area of polygon in square feet. The area of a polygon is defined as total space covered within the shape. The measurement is completed with square units. Rectangles are regular shape. The area of rectangle = length × width

Total area of polygon is equals to the sum of areas of three rectangles. So, area of polygon = 4 ft × 2 ft + 4 ft × 3 ft + 8 ft × 1.2 ft

= 8 ft² + 12 ft² + 9.6 ft²

= 29.6 ft²

Hence, required value is 29.6 ft².

"a lawyer researched the average number of years served by 45 different justices on the supreme court. the average number of years served was 13.8 years with a standard deviation of 7.3 years.

The 95% confidence interval estimate for the average number of years served by all supreme court justices is [11.2, 16.4].According to the central limit theorem , a sampling distribution of the means is usually distributed in a normal distribution, given a big enough sample size, which means that it has a bell-shaped curve. It has a standard deviation that can be estimated by dividing the population standard deviation by the square root of the sample size. Using the formula below,

we can calculate the 95% confidence interval for the population average.= 13.8 ± (1.96 × 7.3 / √45)

= 13.8 ± (1.96 × 1.088)

= 13.8 ± 2.13The limits are calculated by adding and subtracting the calculated value from the sample mean.13.8 + 2.13

= 15.9313.8 - 2.13

first your going to break down your total then since you have nine balls of yarn you going to take out the 9.45

The cost of each wool ball will be $2.14.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

Jessie bought 4 balls of wool to knit sweaters for her children and 5 balls of wool for herself. Then she spent $9.45 on knitting accessories. The total cost of the wool and the accessories was $28.71.

Let x be the cost of each wool ball. Then the equation will be

9x + 9.45 = 28.71

Simplify the equation, then we have

9x = 28.71 - 9.45

9x = 19.26

x = 19.26 / 9

x = $2.14

The cost of each wool ball will be $2.14.

a) The probability that the third car arrives within 3 minutes of the first car is 0.6331.

b) The probability that in a given ten-minutes interval, 15 cars arrive at the booth, and 10 of these are Japanese imports is 0.2023

a) The arrival of cars at the toll booth follows a Poisson process with a rate of 3 arrivals per minute. Let X be the time between the first and third car arrivals. Then X is exponentially distributed with a mean of 1/3 minutes. We want to find the probability that X is less than or equal to 3.

Let Y be the number of car arrivals in the first 3 minutes. Y follows a Poisson distribution with a mean of lambda = 3*3 = 9, since there are 3 minutes and 3 arrivals per minute. Then, the probability that the third car arrives within 3 minutes of the first car is equal to the probability that there are at least 3 arrivals in the first 3 minutes, which is given by:

P(Y >= 3) = 1 - P(Y < 3) = 1 - P(Y = 0) - P(Y = 1) - P(Y = 2)

= 1 - e^(-9) - 9e^(-9) - (81/2)e^(-9)

= 0.6331 (rounded to four decimal places)

Therefore, the probability that the third car arrives within 3 minutes of the first car is 0.6331.

b) Let Z be the number of car arrivals in a 10-minute interval. Z follows a Poisson distribution with a mean of lambda = 10*3 = 30, since there are 10 minutes and 3 arrivals per minute. Let W be the number of Japanese imports in the same 10-minute interval. We are given that 60% of the cars are Japanese imports, so the probability that a given car is a Japanese import is 0.6. Therefore, W follows a binomial distribution with parameters n = Z and p = 0.6.

We want to find the probability that 15 cars arrive at the booth and 10 of them are Japanese imports. This can be calculated using the binomial distribution as follows:

\(P(W = 10 | Z = 15) = (15 choose 10)(0.6)^10(0.4)^5\)

= 0.2023 (rounded to four decimal places)

Here, we assumed that the arrivals are independent and identically distributed, which is a reasonable assumption for a Poisson process. We also assumed that the probability of a car being a Japanese import is the same for each car arrival, which may not be entirely accurate in practice.

The apple will be at the same height of 20ft as the construction worker at t = 3/4sec and t = 5/4sec.

It is given that h = -16t^2 + vt +c

v = 32ft/sec , c = 5ft , h =20ft

So plugging in these values into the formula we have

20 = -16t^2 + 32t + 5

\($\Rightarrow 16t^2 -32t + 15 =0\)

\($\Rightarrow 16t^2 -20t - 12t + 15 =0\)

\($\Rightarrow 4t(4t - 5) -3(4t - 5) = 0\)\($\,\,\,\Rightarrow (4t-3)(4t-5) = 0\)\($\Rightarrow 4t-3 =0 \Rightarrow t = 3/4\,\,\textrm{ and } \,\, 4t-5 =0 \Rightarrow t = 5/4\)

So t = 3/4 and at t = 5/4 are two times when the apple will be at an elevation of h = 20ft.

The motion of an object launched into free motion under gravity is called projectile motion. During this motion, the only force acting on the object is gravity, whose value is -32ft/sec^2. During this motion, the y coordinate is given by \(y = u_yt -(1/2)gt^2 + y_0 = u_yt - 16t^2 + y_0\). here  \(u_y\) is the vertical component of the initial velocity and \(y_0\) is the initial y coordinate. The value of the x coordinate is given by \(x = u_xt\), where \(u_x\) is the horizontal component of the initial velocity.
