The rate of change picking the apples is 8 bushels of apples per hour.

Rate of change is used to mathematically describe the percentage change in value over a defined period of time, the formula for rate of change is: R = (D2 - D1)/T. where: R = rate of change.

Given that, you and your best friend are picking apples at a local orchard. there were already 12 bushels of apples on the tractor when you began at 8:00 am and you picked apples until noon, we are asked to find, what was your rate of change if there were 44 bushels filling the tractor when you stopped,

So, the rate change = total apples picked in 8 am to noon / number of hours.

Therefore, the total apples picked in 8 am to noon =

Since, it was 44 bushels at the end and when they started there were already 12 bushels, so the number of bushels of apples filled between given hours = 44 - 12 = 32 bushels.

The number of hours in picking 32 bushels of apples = 12 noon - 8 am

= 4 hours

Therefore,

The rate of change = 32 / 4

= 8

Hence, the rate of change picking the apples is 8 bushels of apples per hour.

To find the amplitude, period, and frequency of a trigonometric function, you need to examine its equation. Trigonometric functions are typically written in the form:

f(x) = A * sin(Bx + C) + D

where:

• A represents the amplitude,

• B determines the frequency and period,

• C is a phase shift (if any), and

• D is a vertical shift (if any).

Here's how you can find each parameter:

1. Amplitude (A):

The amplitude represents the maximum displacement from the average or mean value of the function. It is the coefficient that multiplies the trigonometric function. In the equation f(x) = A * sin(Bx + C) + D, the amplitude is A.

2. Frequency (f) and Period (T):

The frequency and period are closely related. The period (T) is the length of one complete cycle of the function, while the frequency (f) is the number of cycles per unit of time. The frequency is the reciprocal of the period, so f = 1 / T.

To find the period, you need to look at the coefficient B. If the function is of the form sin(Bx), then the period is given by T = 2π / B. If the function is cos(Bx), the period remains the same.

3. Frequency (f):

Once you have the period (T), you can find the frequency (f) using f = 1 / T.

By examining the equation of the trigonometric function and following the steps above, you can determine the amplitude, period, and frequency of the function.

To find the amplitude, period, and frequency of a trigonometric function, you need to examine the equation representing the function. Here is a explanation.

Amplitude: The amplitude represents the maximum displacement or height of the function from its average or mean value. It is usually denoted as "A" in the trigonometric function equation. To find the amplitude, identify the coefficient multiplying the trigonometric function. If there is no coefficient, the amplitude is assumed to be 1.

Period: The period is the length of one complete cycle of the trigonometric function. It represents the distance between two consecutive peaks or troughs of the function. To find the period, identify the value inside the trigonometric function's argument (the value inside the parentheses) that determines the period. If there is no value, the period is assumed to be 2π.

Frequency: The frequency represents the number of cycles of the trigonometric function that occur per unit interval. It is the reciprocal of the period and is usually denoted as "f." The frequency can be calculated by taking the reciprocal of the period: f = 1/period. By analyzing the equation, you can determine the amplitude, period, and frequency of the trigonometric function, which provide essential information about its behavior and characteristics.

To find the vector v with the same direction as u and a length of 3, we can scale the vector u by a factor of 3 divided by its magnitude.

Given vector u = (1, 2, -1, 0) and the desired length of v as 3, we first need to calculate the magnitude (or length) of vector u.

The magnitude of a vector is computed using the formula:

∥u∥ = √(u1² + u2²+ u3² + u4²), where u₁, u₂, u₃, and u₄ are the components of vector u.

In this case, the magnitude of vector u is √(1² + 2² + (-1)² + 0²) = √6. To find vector v with the same direction as u and a length of 3, we scale u by the factor 3/√6.

This can be done by multiplying each component of u by the scaling factor.

Therefore, vector v = (3/√6) * (1, 2, -1, 0) = (√6/2, √6, -√6/2, 0).

Hence, vector v has the same direction as u and a length of 3.

The perimeter of a rectangle is 40 cm. The length is 14 cm.

Let x = width of the rectangle.

Ravi says he can find the width using the equation 2(x + 14) = 40.

Fran says she can find the width using the equation 2x + 28 = 40.

now, we get,

1. Divide both sides by 2

 2(x+14) = 40

 x+14 = 20

2. Isolate the x term by subtracting 14 from both sides

3. x = 6. The width of the triangle is 6 cm.

4. Isolate the x term by subtracting 28 from both sides

 2x + 28 = 40

 2x = 12

5. Divide both sides by 2

6. x = 6

7. The two equations have the same solution, because by the distributive rule, 2(x+14) = 2x+28.

Answer:

I got -60

I'm pretty good at this.. oop guess I missed a step

Answer:

the dimension of the rectangle is 4 cm and 6 cm respectively

Step-by-step explanation:

The computation of the dimension of the rectangle is shown below:

Given that

The perimeter of the rectangle is 20 cm

The width be x

So, the length would be 2 1 ÷ 4 x - 3 i.e.  9 ÷ 4x - 3

Now as we know that

Perimeter of the rectangle = 2 (length + width)

20 = 2 (9 ÷ 4x - 3 + x)

20 = 9 ÷ 2x - 6 + 2x

20 = 4.5x - 6 + 2x

26 = 6.5x

x = 4 cm

Now the length would be

= 9 × 4  ÷ 4  - 3

= 6 cm

Hence, the dimension of the rectangle is 4 cm and 6 cm respectively

How to find the volume of the cone?

The volume of a cone can be calculated using the formula:

V = (1/3)πr²h

where V is the volume, r is the radius of the base, h is the height, and π is a constant approximately equal to 3.14.

We are given that the pile of pebbles has a height of 10 yards and a base diameter of 6 yards, which means that the radius is 3 yards.

We can use these values to calculate the volume of the pile:

V = (1/3) × 3.14 × 3² × 10

V = 94.2 yd³

Therefore, the pile has a volume of 94.2 cubic yards.

If each truck holds 7.85 yd³ of pebbles, the number of truckloads required can be calculated by dividing the total volume of the pile by the volume of each truck:

Number of truckloads = Volume of pile / Volume of each truck

Number of truckloads = 94.2 / 7.85

Number of truckloads = 12

Therefore, the trucking company will need 12 truckloads to move the pile of pebbles.

The point of diminishing returns is (20.98, 21247.3).

The point of diminishing returns occurs when the marginal cost of producing an extra unit of output exceeds the marginal revenue generated from selling that unit. Mathematically, it is the point at which the derivative of the production function equals zero and the second derivative is negative.

Given the polynomial function N(x) of degree 3, we can find the point of diminishing returns by finding the critical points where the first derivative equals zero and evaluating the second derivative at those points.

The derivative of N(x) is N'(x) = -18x² + 360x + 2250. To find the critical points, we set N'(x) = 0:

0 = -18x² + 360x + 2250

Dividing by -18 simplifies the equation:

0 = x² - 20x - 125

Using the quadratic formula, we find the solutions to the equation:

x₁,₂ = (20 ± √(20² - 4(1)(-125))) / 2(1)

x₁,₂ = 10 ± 5√5

Thus, the two critical points of N(x) are at x = 10 - 5√5 and x = 10 + 5√5.

To determine the point of diminishing returns, we evaluate the second derivative N''(x) = -36x + 360 at these critical points:

N''(10 - 5√5) = -36(10 - 5√5) + 360 ≈ -264.8

N''(10 + 5√5) = -36(10 + 5√5) + 360 ≈ 144.8

From the evaluations, we find that N''(10 + 5√5) is negative while N''(10 - 5√5) is positive. Therefore, the point of diminishing returns corresponds to x = 10 + 5√5.

To find the corresponding y-coordinate (N(10 + 5√5)), we can substitute the value of x into the original function N(x).

Hence, the point of diminishing returns is approximately (20.98, 21247.3).
