The linear function that describes how many square feet of wall she can paint over time is y = 90x.

Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.

Both linear equations with one variable and those with two variables exist.

Given the area painted by Sally in one hour = 90 square feet

so from the given data, we can find that the area painted by Sally is directly proportional to the time,

let she paint for x hours and the area she painted be y,

the equation for the condition is y = 90x,

where x is in hours and y is in square feet,

Table for the area she painted in first 4 hours

x(hours)           1         2        3         4

y ( sq. feet)     90   180    270     360

The graph for the first four hours is attached.

Hence the equation is y = 90x.

Answer:

m=0

Step-by-step explanation:

the slope is calculated using two points on the line and the formula

m = (y2 - y1) ÷ (x2 - x1)

where

x1 and y1 are the coordinates of point 1

x2 and y2 are the coordinates of point 2

for example, you can take

point 1 = (x1;y1) = (-2;3)

point 2 = (x2;y2) = (-1;3)

then your slope is

m = (3 - 3) ÷ (-1 - (-2)) = 0

notice that x1 is always at the left of x2 on the x axis

and it makes sense that your slope is 0 because for each x your y is the same

k = -1

If x-3 is a factor of x4−3x3+kx+3, what is the value of k?

1. The remainder theorem tells us that you get the same thing when you

substitute 3 into a polynomial as you get when you divide the polynomial

by x-3 and take only the remainder.

2. The factor theorem thell us that since x-3 is a factor of the polynomial

then if we divided the polynomial by x-3, the remainder would be 0.

Putting these two facts together we can see that if we substituted 3 into

the polynomial, we will get the same result as the remainder would be if we

divided the polynomial by x-3. And furthermore due to 2, that remainder must

be 0.  So all we have to do is substitute 3 for x in the polynomial and set

it equal to 0.

So substituting 3 for x in x^4-3x^3+kx+3 gives

                          3^4-3(3)^3+k(3)+3

                            81-3(27)+3k+3

                             81-81+3k+3

                                3k+3

Setting 3k+3 = 0

         3k = -3

          k = -1

Now let's check to see if we are right. If we are then the polynomial

x4-3x3^+kx+3 becomes x4-3x3^-x+3. We will divide that

synthetically by x-3 to see if we get a 0 remainder.  First we must

insert a +0x2^ term, and write it as x4^--3x3^+0x2^-x+3

     3 | 1 -3  0 -1  3

       |    3  0  0 -3  

         1  0  0 -1  0    

Sure enough, we do get 0 for a remainder.

So k = -1 is correct.

The equation of the line is (y - 1/12) = -4/3(x - 7/5).

What is the slope of a line?

A line's slope in mathematics is defined as the ratio of the change in the y coordinates to the change in the x coordinate.

Both the net change in the y-coordinate and the net change in the x-coordinate are represented by y and x, respectively.

Consequently, the formula for the change in the y-coordinate with respect to the change in the x-coordinate is

m = y/x = y/x = change in y/change in x

where "m" represents a line's slope.

Additionally, the slope of the line can be depicted by

tan θ = Δy/Δx

So, the slope of a line is tan.

The given equation of a line is:

3x-4y=7

-4y = -3x + 7

y = 3/4 x - 7/4

The slope of the line is 3/4.

The slope of the line perpendicular to the given line is - 1/m = - 4/3

The point-slope of a line is y - y₁ = m(x - x₁).

The given point is (7/5,1/12)

The equation of the line is

(y - 1/12) = -4/3(x - 7/5)

Large Tractors Sold at Break Even Point= 26 units

Small Tractors Sold at Break Even Point= 39 units

Break-even point is where sales are equivalent to the sum of all costs incurred by the company. It is a significant concept in accounting as it gives the managers vital information on how many units must be sold to make business operations profitable.

From the question, it was stated that Wagner Enterprises sells for every three small tractors, two large tractors. Therefore, the sales mix will be:

The contribution margin per unit will be computed first, after which we multiply the sales mix by the computed margin per unit to get the Weighted Average Contribution Margin (WACM). This is shown below:

For Large Tractor:

Selling Price per Unit = $62,000

Variable Cost per Unit = $28,520

Contribution Margin per Unit = ($62,000 - $28,520) = #33,480

Multiply by sales-mix of 2/5 = 2/5 times $33,480 = 13,392 (WACM)

For Small Tractor:

Selling Price per Unit = $34,000

Variable Cost per Unit = $16,320

Contribution Margin per Unit = ($34,000 - $16,320) = #17,680

Multiply by sales-mix of 3/5 = 3/5 times $17,680 = 10,608 (WACM)

The Total Weighted Average Contribution Margin per unit is therefore:

$13,392 + $10608, equaling $24,000.

Now we can find the Break-even Point in Unit.

Formula for Break-even Point in Unit = Total Fixed Cost (TFC) divided by Weighted Average Contribution Margin in unit

Total Fixed Costs = $1,560,000

WACM in unit = $24,000

Break-Even Point = \(\frac{1,560,000}{24,000}\) = 65 units

From the calculations, the total units that must be sold to break-even are equivalent to 65 units. Given the above sales mix, the 65 units will be shared thus:

Therefore, 26 units of Large Tractors and 39 units of Small Tractors were sold at Wagner's Enterprise break-even point.

The primitive function for \(f(x) = 4e^{2x} + e^{-x}\) is given by it's indefinite integral.

To calculate it, recall:

\(\frac{d}{dx}e^{ax}=ae^{ax}\)

\(\int c f(x)dx = c\int f(x)dx\)

Let's begin

\(\int 4e^{2x}+e^{-x}dx \\4\int e^{2x}dx+ \int e^{-x}dx\\4\frac{e^{2x}}{2}+\frac{e^{-x}}{-1} + c\\\)

\(F(x) = 2e^{2x}-e^{-x} +c\)

To find the costant, we just need to use the fact that \(F(0)=2\)

\(F(0) = 2 \\4e^{0}+e^{0} + c =2\\5+c =2\\c=-3\)

Therefore,

\(\boxed{F(x) = 2e^{2x} - e^{-x} -3 }\)

The function g(x) = 2f(6x) + 8 is a function transformation of the function f(x)

The function g(x) is given as:

g(x) = 2f(6x) + 8

The table is not given.

So, I will provide a general explanation

Using the following values of x:

x = 0, 1, 2, 3......

We have:

g(0) = 2f(6 *0) + 8

g(0) = 2f(0) + 8

g(1) = 2f(6 *1) + 8

g(1) = 2f(6) + 8

g(2) = 2f(6 *2) + 8

g(2) = 2f(12) + 8

g(3) = 2f(6 *3) + 8

g(3) = 2f(18) + 8

Next, we assume the following values

f(0) = 4, f(6) = 5; f(12) = 6 and f(18) = 7

The values become:

g(0) = 2f(0) + 8 = 2 * 4 + 8 = 16

g(1) = 2f(6) + 8 = 2 * 5 + 8 = 18

g(2) = 2f(12) + 8 = 2 * 6 + 8 = 20

g(3) = 2f(18) + 8 = 2 * 7 + 8 = 22

So, the table of values would be:

When substituting y = 11 into the equation y = 1/2(x) - 25, we find that x = 72, confirming that (23.5, 11) is a valid point of intersection.

Given that x is 23.5, it is required to prove that it is an intersection point for the equation y = 1/2(x) - 25 when y is equal to 11.

The equation is given as y = 1/2(x) - 25

When y = 11, we can substitute the value of y in the equation to obtain 11 = 1/2(x) - 25

This can be simplified as 11 + 25 = 1/2(x)36 = 1/2(x)

On solving, x = 72Thus, when y is equal to 11 and x is equal to 72, the given point of intersection is valid.

Therefore, it can be concluded that x = 23.5 is a point of intersection for the equation y = 1/2(x) - 25 when y is equal to 11.

In summary, when given an equation with two variables, we can find the point of intersection by setting one of the variables to a given value and solving for the other variable. In this case, when y is equal to 11, we can solve for x and obtain the point of intersection as (72,11).

The trigonometric ratios are

Trigonometric ratios are the ratio of the sides of a right-angled  triangle.

Given the triangle ΔABC to find sinA, we use the trigonometic ratio

SinA = opposite/adjacent = CB/AB

Now, we find CB by pythagoras' theorem.

AB² = CB² + AC²

CB = √(AB² - AC²)

So, substituting these into the equation, we have

SinA = CB/AB

= √(AB² - AC²)/AB

= √[(AB² - AC²)/AB²]

= √[1 - (AC/AB²]

Given that

So, substituting these into the equation, we haveCB = √(144² - 70²)

SinA = √(AB² - AC²)/AB

SinA = √(144² - 70²)/144

SinA = √(20736 - 4900)/144

SinA = √15836/144

SinA = 125.84 in/144 in

SinA = 0.8738

To evaluate CosB, we use the trigonometric ratio

CosB = adjacent/hypotenuse

= AC/AB

Given that

CosA = AC/AB

= 70 in/144 in

= 35/72

To evaluate TanA use the trigonometric ratio

CosA = opposite/adjacent

Given that

CosA = CB/AC

=  √(AB² - AC²)/AC

Answer:

1/ 4^10

(ONE on top of a fraction. Four to the tenth power on the bottom of the fraction)

Step-by-step explanation:

When you have a power to a power the short cut (exponent rule) says to multiply the powers.

(4^-2)^5

Keep the same base, the 4

times -2 × 5, you get -10

so far after one step, you have

4^-10

Now usually, you would not leave an exponent negative. So to "fix" the negative exponent, you change it to positive by "pushing it" across the fraction bar.

4^-10

becomes:

1/ 4^10

This is a ONE on top of a fraction and FOUR to the tenth power on the bottom of the fraction.

The answer is:

1/4¹⁰

Work/explanation:

For this problem, I'm going to use the following exponent law:

\(\boxed{\!\!\boxed{\quad\sf{(x^m)^n=x^{mn}}\quad}\!\!}\)

So if we have "a power to a power", we multiply the powers.

And now that we're familiar with this property let's apply it.

\(\sf{(4^{-2})^5=4^{-2\times5}=4^{-10}}\)

Here the next exponent law comes into play.

______________________

\(\boxed{\!\!\boxed{\quad\sf{x^{-m}\:\:=\:\:\dfrac{1}{x^m}\quad}}\!\!}\)

So if we have a number raised to a negative power, we flop it over.

Let's apply the law to our problem now.

Our problem is:

\(\sf{4^{-10}\)

According to the law above, we should do the following:

\(\sf{4^{-10}=\dfrac{1}{4^{10}}}\)

It's better to leave the answer as it is.

Hence, the answer is 1/4¹⁰

TJohn's age is approximately 23.33 years, and Sharon's age is approximately 93.33 years.

And the correct graph is D.

To represent the given problem as a system of equations, we can use the following information:

John is 70 years younger than Sharon: j = s - 70

Sharon is 4 times as old as John: s = 4j

Let's plot the graph for this system of equations:

First, let's solve equation (2) for s:

s = 4j

Now substitute this value of s in equation (1):

j = s - 70

j = 4j - 70

3j = 70

j = 70/3

Substitute the value of j back into equation (2) to find s:

s = 4j

s = 4(70/3)

s = 280/3

The solution to the system of equations is j = 70/3 and s = 280/3

In the graph d, the solution to the system of equations is represented by the point (70/3, 280/3), which is approximately (23.33, 93.33) on the graph.

Therefore, John's age is approximately 23.33 years, and Sharon's age is approximately 93.33 years.
