So the average rate of change of the function over the interval 0 ≤ x ≤ 15 is 4.4.

What is function?

In mathematics, a function is a relationship between two sets of numbers, where each input in the first set (called the domain) corresponds to exactly one output in the second set (called the range). In other words, a function takes an input, performs a specific operation on it, and produces an output. A function is usually denoted by a symbol (often a letter) and is defined by a rule that specifies how to calculate the output value for any given input value.

Here,

To find the average rate of change of the function over the interval 0 ≤ x ≤ 15, we need to calculate the change in the function value divided by the change in x over the interval.

The change in the function value over the interval is f(15) - f(0), which is 159 - 93 = 66.

The change in x over the interval is 15 - 0 = 15.

Therefore, the average rate of change of the function over the interval 0 ≤ x ≤ 15 is:

average rate of change = change in f / change in x

= 66 / 15

= 4.4

(b) Find the costs of supplying bins to 10%, 50%, and 85% of the
cost to supply 10%
C = $
X
cost to supply 50%
C = $25,000
cost to supply 85%
C = $ 141,667

Answers

Answer:

To find the cost of supplying bins to 10%, 50%, and 85% of the cost to supply 10%, we can use proportional reasoning.

Let X be the cost to supply 10%. Then:

The cost to supply 50% is 5 times the cost to supply 10%, so it is 5X.

The cost to supply 85% is 8.5 times the cost to supply 10%, so it is 8.5X.

The cost to supply 10% is X.

To find the cost of supplying bins to 10%, 50%, and 85% of the cost to supply 10%, we can substitute X = $1 and multiply by the appropriate percentages:

The cost to supply bins to 10% of the cost to supply 10% is 0.1 * X = 0.1 * $1 = $0.10.

The cost to supply bins to 50% of the cost to supply 10% is 0.5 * X = 0.5 * $1 = $0.50.

The cost to supply bins to 85% of the cost to supply 10% is 0.85 * X = 0.85 * $1 = $0.85.

Therefore, the costs of supplying bins to 10%, 50%, and 85% of the cost to supply 10% are $0.10, $0.50, and $0.85, respectively.

Answer:

Let the cost to supply 10% of the bins be X dollars.

To find the cost of supplying bins to 50% of the cost to supply 10%, we can set up the following proportion:

10% of the cost = X dollars

50% of the cost = Y dollars

We know that the two costs are proportional, so we can set up the following equation:

10% / 50% = X / Y

Simplifying this equation, we get:

0.1 / 0.5 = X / Y

0.2 = X / Y

Multiplying both sides by Y, we get:

Y * 0.2 = X

Y = X / 0.2

Y = 5X

Therefore, the cost of supplying bins to 50% of the cost to supply 10% is 5 times the cost of supplying bins to 10%.

Substituting X = C/10 (where C is the cost to supply 10% of the bins), we get:

Y = 5X = 5(C/10) = C/2

So the cost of supplying bins to 50% of the cost to supply 10% is C/2 dollars.

To find the cost of supplying bins to 85% of the cost to supply 10%, we can set up a similar proportion:

10% of the cost = X dollars

85% of the cost = Z dollars

We know that the two costs are proportional, so we can set up the following equation:

10% / 85% = X / Z

Simplifying this equation, we get:

0.1 / 0.85 = X / Z

0.1176 = X / Z

Multiplying both sides by Z, we get:

Z * 0.1176 = X

Z = X / 0.1176

Z = 8.5X

Therefore, the cost of supplying bins to 85% of the cost to supply 10% is 8.5 times the cost of supplying bins to 10%.

Substituting X = C/10 (where C is the cost to supply 10% of the bins), we get:

Z = 8.5X = 8.5(C/10) = 0.85C

So the cost of supplying bins to 85% of the cost to supply 10% is 85% of the cost to supply 10%, or 0.85C dollars.

Therefore, the costs of supplying bins to 10%, 50%, and 85% of the cost to supply 10% are:

- 10% of the cost: X dollars = C/10 dollars

- 50% of the cost: Y dollars = C/2 dollars

- 85% of the cost: Z dollars = 0.85C dollars

Consider the following function.

Step 2 of 2 : Find two points on the line to graph the function.

Answers

We can plot (0, 4) and (1, -28) points on a coordinate plane and draw a straight line passing through both points to graph the function.

What is a coordinate plane?

A coordinate plane, also known as a Cartesian plane, is a two-dimensional plane that is used to plot points and graph mathematical equations. It consists of two perpendicular number lines called the x-axis and the y-axis. The x-axis is the horizontal line, with positive values to the right of the origin (0) and negative values to the left of the origin. The y-axis is the vertical line, with positive values above the origin and negative values below the origin. The x-coordinate gives the horizontal position of the point, and the y-coordinate gives the vertical position of the point. By plotting points on a coordinate plane, we can graph lines, curves, and other mathematical functions. It is a fundamental tool in mathematics, science, and engineering for visualizing and analyzing relationships between variables.

To find two points on the line of the function r(x) = 4 - 32x, we can simply choose any two values of x and find the corresponding values of r(x).

For example, when x = 0:

r(0) = 4 - 32(0) = 4

So one point on the line is (0, 4).

When x = 1:

r(1) = 4 - 32(1) = -28

So another point on the line is (1, -28).

Therefore, we have two points on the line: (0, 4) and (1, -28).

We can plot these points on a coordinate plane and draw a straight line passing through both points to graph the function.

The solution to the trigonometric expression is given as follows:

How to solve the trigonometric expression?

The trigonometric expression for this problem is defined as follows:

sin(x)(1 + tan(x)) + cos(x)(1 + cot(x)).

The tangent and the cotangent are represented as follows:

tan(x) = sin(x)/cos(x).cot(x) = cos(x)/sin(x).

Hence:

sin(x)(1 + tan(x)) + cos(x)(1 + cot(x)) = sin(x)[1 + sin(x)/cos(x)] + cos(x)[1 + cos(x)cot(x)]

sin(x)(1 + tan(x)) + cos(x)(1 + cot(x)) = sin(x)+sin²(x)/cos(x) + cos(x) + cos²(x)/sin(x)

sin(x)(1 + tan(x)) + cos(x)(1 + cot(x)) = [sin²(x)cos(x) + sin³(x) + sin(x)cos²(x) + cos³(x)]/(sin(x)cos(x))

Can you please give a detailed explanation so I can understand

Answers

The sequence generated by the formula f(n) = (4n - 7) starting with n = 1 is: -3, 1, 5, 9, 13

What is functions?

A function is typically denoted by a symbol, such as "f(x)", where "x" is the input value and "f(x)" is the output value. The input value is sometimes referred to as the "argument" of the function.

The formula f(n) = (4n - 7) generates a sequence of numbers when we plug in different values of "n". To generate the terms f(1), f(2), f(3), f(4), f(5) we need to substitute each value of n into the formula and evaluate the expression.

Starting with n = 1, we can generate the terms as follows:

f(1) = (4 × 1 - 7) = -3

f(2) = (4 × 2 - 7) = 1

f(3) = (4 × 3 - 7) = 5

f(4) = (4 × 4 - 7) = 9

f(5) = (4 × 5 - 7) = 13

So the sequence generated by the formula f(n) = (4n - 7) starting with n = 1 is: -3, 1, 5, 9, 13

Each term in the sequence is found by plugging in a different value of "n" into the formula f(n) = (4n - 7). The first term, f(1), is found by plugging in n = 1, the second term, f(2), is found by plugging in n = 2, and so on.

Jayla is training for the Seaview sprint race she runs the same route in her neighborhood every day and she makes her go on 80% of the time she plans to run every day for the next 10 days how likely that will she make her goal every day

Answers

If Jayla makes her goal 80% of the time, we can say that she has a probability of 0.8 of achieving her goal on any given day.

The probability of Jayla making her goal every day for the next 10 days can be calculated by multiplying the probability of her achieving her goal on each day.

Assuming each day's result is independent of the previous day, the probability of Jayla making her goal every day for the next 10 days is:

0.8 x 0.8 x 0.8 x 0.8 x 0.8 x 0.8 x 0.8 x 0.8 x 0.8 x 0.8 = 0.1073741824

According to the given problem, the linear regression line for the given data is y = -0.65 + 0.26x

What is linear regression?

Linear regression is a statistical method used to find the relationship between a dependent variable (y) and one or more independent variables (x). It assumes that there is a linear relationship between the variables, meaning that changes in the independent variable(s) are associated with proportional changes in the dependent variable.

The linear regression model can be represented as a straight-line equation:

y = b0 + b1*x + e

The equation of a linear regression line can be written as:

y = b0 + b1*x

where y is the dependent variable (car sales in this case), x is the independent variable (number of TV commercials), b0 is the intercept, and b1 is the slope of the line.

To find the values of b0 and b1, we need to calculate the following:

n = number of data points = 4

Σx = sum of x values = 54

Σy = sum of y values = 28

Σxy = sum of (x*y) values = 164

Σx^2 = sum of (x^2) values = 689

Using these values, we can calculate b1:

b1 = (nΣxy - ΣxΣy) / (n*Σx^2 - Σx^2)

b1 = (4164 - 5428) / (4*689 - 54^2)

b1 = 0.26 (rounded to two decimal places)

Next, we can use b1 to calculate b0:

b0 = (Σy - b1*Σx) / n

b0 = (28 - 0.26*54) / 4

b0 = -0.65 (rounded to two decimal places)

Therefore, the linear regression line for the given data is:

y = -0.65 + 0.26x

At the end of the third quarter, the balance is:

$1025.16 + $1025.16(1.25%) = $1025.16 + $12.82 = $1037.98

At the end of the fourth quarter, the balance is:

$1037.98 + $1037.98(1.25%) = $1037.98 + $13.00 = $1050.98

Therefore, the year-end balance is $1050.98 (rounded to the nearest penny).

Part a: Assume that the height of your cylinder is 8
inches. Consider A
as a function of r
, so we can write that as A(r)=2πr2+16πr
. What is the domain of A(r)
? In other words, for which values of r
is A(r)
defined?



Part b: Continue to assume that the height of your cylinder is 8
inches. Write the radius r
as a function of A
. This is the inverse function to A(r)
, i.e., to turn A
as a function of r
into r
as a function of A
.

Hints:

To calculate an inverse function, you need to solve for r
. Here, you would start with A=2πr2+16πr
. This equation is the same as 2πr2+16πr−A=0
which is a quadratic equation in the variable r
, and you can solve that using the quadratic formula. You will want to keep A
as a variable when you plug the values into the quadratic formula.

Hence, in answering the stated question, we may say that We know, equation however, that r must be positive, therefore we take the positive square root: [tex]r(A) = -4 + square root(64 + 2A) /[/tex]

What is equation?

A math equation is a method that links two claims and represents equivalence using the equals sign (=). An equation is a mathematical statement that establishes the equivalence of two mathematical expressions in algebra. In the equation 3x + 5 = 14, for example, the equal sign separates the numbers 3x + 5 and 14. A mathematical formula may be used to describe the relationship between the two sentences on opposite sides of a letter. In usually, the logo and the programme are the same. For instance, 2x - 4 equals 2.

Part a: Because the radius of a cylinder must be a positive real integer, the domain of A(r) is the set of all real numbers greater than zero.

As a result, the domain of A(r) is:

{r ∈ ℝ | r > 0}

Part b: To determine the inverse function r(A), solve the equation A = 2r2 + 16r for r expressed in terms of A.

To begin, we may simplify the equation by removing 2r:

A = 2πr(r + 8)

Hence, using the quadratic formula, we can find r:

[tex]r = (-16 \sqrt((16)2 - 4(2 )(-A)) / 2(2 )\\r = (-16 \sqrt(2562) + 8A) / 4 r = -4 \sqrt(64 + 2A) /[/tex]

We know, however, that r must be positive, therefore we take the positive square root:

[tex]r(A) = -4 + square root(64 + 2A) /[/tex]

What is equatiοn?

A math equatiοn is a methοd that links twο claims and represents equivalence using the equals sign (=). An equatiοn is a mathematical statement that establishes the equivalence οf twο mathematical expressiοns in algebra.

Part a: The dοmain οf A(r) is the set οf all real numbers greater than οr equal tο zerο since the radius οf a cylinder cannοt be negative.

Dοmain οf A(r): r ≥ 0

Part b: Tο find the inverse functiοn r(A), we start with the equatiοn fοr A(r), set it equal tο A, and sοlve fοr r using the quadratic fοrmula:

[tex]2 \pi r^2 + 16 \pi r - A = 0[/tex]

[tex]r = [-16 \pi \± \sqrt{((16 \pi)^2 - 4(2 \pi)(-A))}] / 2(2 \pi)[/tex]

[tex]r = [-16\pi \± \sqrt{(256\pi^2 + 8 \pi A)}] / 4\pi[/tex]

Simplifying this expressiοn, we get:

[tex]r = (-4 \± \sqrt{(64 + 2A)}) / 2[/tex]

[tex]r(A) = -2 \± \sqrt{(32 + 0.5A)[/tex]

Since the radius οf a cylinder cannοt be negative, we take the pοsitive square rοοt:

[tex]r(A) = -2 + \sqrt{(32 + 0.5A)[/tex]

Part c: Tο find the radius when the surface area is 300 square inches, we plug in A = 300 intο the expressiοn fοr r(A) and simplify:

[tex]r(300) = -2 + \sqrt{(32 + 0.5(300))[/tex]

r(300) = -2 + sqrt(182)

r(300) ≈ 11.51

Therefοre, the radius is apprοximately 11.51 inches when the surface area is 300 square inches.

Fοr the fifth mοnth, priοr balance is $4469.69, interest οn priοr balance is $77.78, mοnthly payment is $175, and ending balance is $4389.72.

What is annual interest rate?

Annual interest rate is the amοunt οf interest that is charged οn a lοan οr investment per year, expressed as a percentage οf the amοunt bοrrοwed οr invested.

Tο cοmplete the table, we can use the fοllοwing steps:

Fοr the first mοnth:

Priοr balance: $4900

Interest οn priοr balance: 1.75% οf $4900 = $85.75 (rοunded tο the nearest cent)

Mοnthly payment: $175

Ending balance: $4900 + $85.75 - $175 = $4710.75 (rοunded tο the nearest cent)

Fοr the secοnd mοnth:

Priοr balance: $4710.75

Interest οn priοr balance: 1.75% οf $4710.75 = $82.46 (rοunded tο the nearest cent)

Mοnthly payment: $175

Ending balance: $4710.75 + $82.46 - $175 = $4628.21 (rοunded tο the nearest cent)

Repeat the same prοcess fοr the next three mοnths:

Fοr the third mοnth, priοr balance is $4628.21, interest οn priοr balance is $80.89, mοnthly payment is $175, and ending balance is $4549.10.

Fοr the fοurth mοnth, priοr balance is $4549.10, interest οn priοr balance is $79.34, mοnthly payment is $175, and ending balance is $4469.69.

Answer:
The area is given by the expreesion:

A  = 5f + 10

Step-by-step explanation:

Notice the height of the shaded area is 5. But the base is the difference between f+9 and 7
So the length of the shaded area will be f+9-7=f+2

then the area of a rectangle is given by A=height*length
This is
A = 5 (f+2) = 5f+10

Question: Write an expression for the area shaded section of this rectangle. Expand your brackets


The area of shaded section is 5f+10

Rectangular area concepts

To calculate the area of ​​the rectangle, it is known that just multiply the measurement of the height by the length.

So, to calculate the value of the area of ​​this rectangle considering that the shaded area is part of it, we would do [tex]\sf f+9\times5[/tex].

The area of ​​the shaded section will be given by the difference between the area of ​​the shaded area and the unshaded area.

That is, [tex]\sf(f+9-7)\times5[/tex]

Let's calculate

[tex]\begin{array}{l}\sf(f+9-7)\times5\\\sf(f+2)\times5\\\sf 5f+2\times5\\\therefore \bf 5f+10\end{array}[/tex]

5f+10 is the shaded section area expression
