The ratio of apples to pears at a farm stand is 5:3. What is the percentage of the fruit to apples?

Answer:

The distance between points (4, -2) and (4,4) on a coordinate plane is 6 units. This is because the two points lie on the same vertical line, where the x-coordinate remains constant at 4. To find the distance between them, we simply need to subtract their y-coordinates: 4 - (-2) = 6. Therefore, the distance between the two points is 6 units.

The mean absolute deviation of the entire data set is 4.

To find the mean absolute deviation (MAD) of the given data set, we need to follow these steps:

Calculate the mean (average) of the data set.

Subtract the mean from each data point to find the deviation.

Take the absolute value of each deviation.

Calculate the mean of the absolute deviations.

Let's calculate the MAD for the given data set: 18, 13, 6, 14, 11, 22.

Calculate the mean.

Mean = (18 + 13 + 6 + 14 + 11 + 22) / 6 = 84 / 6 = 14.

Calculate the deviation for each data point.

Deviation = data point - mean.

Deviation for 18 = 18 - 14 = 4.

Deviation for 13 = 13 - 14 = -1.

Deviation for 6 = 6 - 14 = -8.

Deviation for 14 = 14 - 14 = 0.

Deviation for 11 = 11 - 14 = -3.

Deviation for 22 = 22 - 14 = 8.

Take the absolute value of each deviation.

Absolute deviation = |deviation|.

Absolute deviation for 4 = |4| = 4.

Absolute deviation for -1 = |-1| = 1.

Absolute deviation for -8 = |-8| = 8.

Absolute deviation for 0 = |0| = 0.

Absolute deviation for -3 = |-3| = 3.

Absolute deviation for 8 = |8| = 8.

Calculate the mean of the absolute deviations.

Mean absolute deviation = (4 + 1 + 8 + 0 + 3 + 8) / 6 = 24 / 6 = 4.

Step-by-step explanation:

The diameter of the circle is approximately 947.15 meters.

What is a circle?

It is the center of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

The formula for the circumference of a circle is:

C = 2πr

where C is the circumference and r is the radius of the circle.

We can use this formula to find the radius of the circle given its circumference:

C = 2πr

942 = 2πr

Dividing both sides by 2π, we get:

r = 942/2π

Now, we can use the formula for the diameter of a circle in terms of its radius:

d = 2r

Substituting the value we found for r, we get:

d = 2(942/2π) = 942/π

Using a calculator to approximate π as 3.14, we can evaluate the expression to get:

d ≈ 947.15 meters

Therefore, the diameter of the circle is approximately 947.15 meters.

Thus, the length of walk way around the filed is the perimeter of the right triangle which is found as: 206.023 m .

The quickest approach to determine a triangle's perimeter is to sum up all of its sides' lengths, but you must first determine each side's length if you don't already know it.

The walk way around the filed is the perimeter of the right triangle.

walk way = base + height + hypotenuse

walk way = B + P + H

base B = 80 - 10 = 70 m

Altitude P = 70 - 20 = 50 m

For the hypotenuse H , use the Pythagorean theorem:

H² = B² + P²

H² = 70² + 50²

H² = 4900 + 2500

H² = 7400

H = 86.023

So,

walk way = B + P + H

walk way = 70 + 50 + 86.023

walk way = 206.023 m

Thus, the  walk way around the filed is the perimeter of the right triangle which is found as: 206.023 m .

Answer:

To solve this problem using cylindrical coordinates, we need to express the integrand and the limits of integration in terms of cylindrical coordinates. In cylindrical coordinates, a point in 3D space is represented by the radius (r), the angle (theta), and the height (z), where:

x = r cos(theta)

y = r sin(theta)

z = z

The volume element in cylindrical coordinates is given by:

dV = r dr dtheta dz

Now we can write the integral as:

∫∫∫W(x^2+y^2)dV = ∫∫∫W(r^2) r dr dtheta dz

The limits of integration are given by:

0 ≤ z ≤ 2 (since the region of integration is between z=0 and z=2)

0 ≤ r ≤ 5 (since the region of integration is within the circle of radius 5 in the xy-plane)

0 ≤ theta ≤ 2π (since the region of integration extends throughout the entire circle in the xy-plane)

Therefore, we can write the integral as:

∫∫∫W(r^2) r dr dtheta dz

= ∫0^2 ∫0^5 ∫0^2 (r^2) r dz dr dtheta

Integrating with respect to z first, we get:

∫0^2 ∫0^5 ∫0^2 (r^2) r dz dr dtheta

= ∫0^2 ∫0^5 [(r^2) r (2-0)] dr dtheta

= 2 ∫0^5 (r^3) dr ∫0^2 dtheta

= 2 (1/4) (5^4) (2)

= 1250

Therefore, the value of the integral is 1250.

Answer:

To approximate the positive zero of the given polynomial function f(x), we can use numerical methods such as the Newton-Raphson method or the bisection method. Here, we will use the latter method.

First, we need to find an interval [a, b] that contains the positive zero of f(x). We can do this by observing the behavior of the function near the origin and near large positive values of x. We can see that f(0) = -1 is negative and that f(x) becomes more and more negative as x approaches infinity. This suggests that the positive zero of f(x) is somewhere in the interval (0, infinity).

We can evaluate f(x) at x = 1 and x = 2 to determine which half of the interval contains the positive zero. We have:

f(1) = 2(1)² - 1 - 16(1)³ - 3(1)² - 8(1) - 2 = -24

f(2) = 2(2)² - 1 - 16(2)³ - 3(2)² - 8(2) - 2 = -207

Since f(1) is negative and f(2) is very negative, we can conclude that the positive zero of f(x) is in the interval (1, 2).

Next, we can use the bisection method to refine the interval and approximate the positive zero to two decimal places. We start by evaluating f(c), where c is the midpoint of the interval (1, 2):

c = (1 + 2)/2 = 1.5

f(c) = 2(1.5)² - 1 - 16(1.5)³ - 3(1.5)² - 8(1.5) - 2 ≈ -97.875

Since f(c) is negative, the positive zero of f(x) must be in the interval (c, 2). We can repeat the process by finding the midpoint of this interval:

c = (1.5 + 2)/2 = 1.75

f(c) = 2(1.75)² - 1 - 16(1.75)³ - 3(1.75)² - 8(1.75) - 2 ≈ -38.104

Again, f(c) is negative, so the positive zero of f(x) must be in the interval (c, 2). We can repeat the process until the interval is small enough to obtain the desired level of accuracy.

Using a calculator or a computer program, we can continue the bisection method and find that the positive zero of f(x) is approximately 1.49, rounded to two decimal places.

Juan's claim is plausible based on the given function because the maximum height of the ball is 62.875 feet, which is higher than the 50-foot light tower.

To prove that Juan hit the ball over the 50-foot light tower, we need to find the maximum height of the ball using the given function h(x) = -16x^2 + 60x + 4 and show that the maximum height is greater than 50 feet.

The maximum height of the ball occurs at the vertex of the parabolic function h(x), which is given by the formula x = -b/2a, where a = -16 and b = 60.

Substituting these values into the formula, we get:

x = -b/2a = -60/(2*(-16)) = 1.875

So the ball reaches its maximum height after 1.875 seconds. To find the maximum height, we can substitute this value of x into the original function h(x):

h(1.875) = -16(1.875)^2 + 60(1.875) + 4 = 62.875

Answer:

The mean of the numbers 5, 3, 6, x, 9, and 10 is given as 7.

To find the value of x, we can use the formula for the mean:

mean = (sum of all the numbers) / (number of numbers)

In this case, we have:

7 = (5 + 3 + 6 + x + 9 + 10) / 6

Multiplying both sides of the equation by 6, we get:

42 = 33 + x

Subtracting 33 from both sides of the equation, we get:

x = 9

Therefore, the value of x that makes the mean of 5, 3, 6, x, 9, and 10 equal to 7 is 9.

Given:

Initial deposit (P) = $7,500

Interest rate (r) = 3.4% or 0.034 (decimal)

Compounding frequency (n) = 2 (semi-annually)

We can use the compound interest formula to calculate the values:

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

Where:

A = the final amount (including interest)

P = the principal amount (initial deposit)

r = the interest rate (in decimal)

n = the number of times interest is compounded per time period

Answer: 11

Step-by-step explanation: To find the value of (fog)(-1), we first need to find the value of g(-1), which means plugging -1 into the equation for g(x):

g(x) = x² – 5x - 5

g(-1) = (-1)² – 5(-1) - 5

g(-1) = 1 + 5 - 5

g(-1) = 1

Now we need to find (fog)(x) by plugging g(x) into f(x) and simplifying:

f(x) = -x - 12

fog(x) = f(g(x))

fog(x) = f(x² – 5x - 5)

fog(x) = -(x² – 5x - 5) - 12

fog(x) = -x² + 5x + 17

Finally, we can find (fog)(-1) by plugging -1 into the equation for fog(x):

fog(x) = -x² + 5x + 17

(fog)(-1) = -(-1)² + 5(-1) + 17

(fog)(-1) = -1 - 5 + 17

(fog)(-1) = 11

Therefore, the value of (fog)(-1) is 11.

Part C. I choose the point (1,3) in the solution set. This implies that Michael can buy 1 cupcake and 3 pieces of fudge with $16 as well as feed at least 4 siblings.

Part A: The inequalities limit Michael's purchase of cupcakes and fudge with $16 to feed at least 4 siblings. The first one, 4x + 2y ≤ 16, restricts the total cost to be $16 or less. To graph y ≤ -2x + 8, draw the line with slope -2 and y-intercept 8, and shade below it. The inequality x + y ≥ 4 means Michael must feed at least 4 siblings. It can be graphed as y ≥ -x + 4, a line with slope -1 and y-intercept 4. To graph the inequality, draw a dashed line with slope -1 and y-intercept 4. Shade the region above the line for y ≥ -x + 4. The solution set is the intersection of the shaded regions. Triangle with vertices (0,4), (2,3), and (4,0).

We have,

Let's start by assigning variables to unknown quantities.

Let m be the time it takes for Mike to wash the car alone (in minutes).

We know that Stephanie takes 17 minutes to wash the car alone, so her rate of work is 1/17 car per minute.

Working together, their combined rate of work is 1/8.24 car per minute.

Using the formula:

(rate of work) = (amount of work) / (time)

we can set up the following equation to represent the work they do together:

1/8.24 = (1 car) / t

where t is the time it takes them to wash the car together.

We can also set up a similar equation for Stephanie's work alone:

1/17 = (1 car) / (t + x)

where x is the extra time it takes Mike to wash the car alone.

Since they are working on the same car, the amount of work done in both cases is the same, so we can set the two equations equal to each other and solve for x:

1/8.24 = 1/(t + x) + 1/17

Multiplying both sides by the least common multiple of the denominators (8.2417(t+x)).

17*(t+x) + 8.24*(t+x) = 8.24*17

Simplifying.

25.24t + 17x = 139.68

We also know that Mike's rate of work is 1/m car per minute.

Since we know the combined rate of work when they work together, we can set up another equation:

1/m + 1/17 = 1/8.24

Multiplying both sides by the least common multiple of the denominators (8.2417m).

178.24m + 8.2417m = 8.2417m + m8.24m

Simplifying.

141.08m = 139.68
