Step-by-step explanation:

The answer is K^2 = 711.6Y on solving the given equation.

Given that, 1 = 711.6Y/K^2 and we have to solve it for the value of K^2. For this we simply have to solve the given equation steps wise. So, let's proceed to solve the equation.

1 = 711.6Y/K^2

Now, multiply K^2 with 1, we get

K^2 = 711.6Y

So, the value of k^2 will be equal to Y times 711.6 and further we can solve it for the various value of Y.

Let us suppose, we have to solve the above equation for the specific value of Y.

So, put Y = 1

On solving, we get

K^2 = 711.6x1

K^2 = 711.6

K = (711.6)^(1/2)

K = 26.67

∴ K^2 = 711.6Y is the equation we will get on solving the equation given to us in the question.

Hence, K^2 = 711.6Y is the required answer.

Step-by-step explanation:

The maximum revenue obtained for the given revenue function is 43340.

Maxima and minima are the highest and lowest values of a function within a given set of ranges.

Now, as per the given question;

The given revenue function is;  R(x) = 395x − 0.9x²

Differentiate the given function with respect to x.

dR/dx = 395 − 2×0.9x

dR/dx = 395 - 1.8x

Put the given equation equal to zero and find the critical point for which the function will become maximum.

395 - 1.8x = 0

x = 219.44

x ≈≈ 220.

Substitute the obtained value of x in the revenue function to find its maximum value.

R(x) = 395x − 0.9x²

R(220) = 395×220 − 0.9(220)²

R(220) = 86900 - 43560

R(220) = 43340.

Therefore, the maximum revenue calculated for the given revenue function is 43340.

Answer:

[tex]z - 0.05z = 236.60[/tex]

Step-by-step explanation:

Given

[tex]Discount = 5\%[/tex]

[tex]Total\ Cost = 236.60[/tex]

Represent the cost of goods bought with z

When the coupon is applied, the discount becomes

[tex]Discount = 5\% * z[/tex]

This gives:

[tex]Discount = 0.05 * z[/tex]

[tex]Discount = 0.05z[/tex]

The discount subtracted from the cost of good will gives the total amount paid.

So, we have:

[tex]Cost\ of\ Goods - Discount = Total\ Cost[/tex]

This gives:

[tex]z - 0.05z = 236.60[/tex]

Hence, option (a) is correct

Answer:

A. 3(2x - 12) = 2(3 + 2x - 12)

B. Length = 6, width = 3

Step-by-step explanation:

l = 2x - 12

w = 3

Area = 3(2x - 12)

Perimeter = 2(3 + 2x - 12)

if A = P

3(2x - 12) = 2(3 + 2x - 12)

6x - 36 = 6 + 4x - 24

6x - 4x = 6 - 24 + 36

2x = 18

x = 9

Length = 2x - 12 = 2(9) - 12 = 18 - 12 = 6

Answer:

(r o q)(-1) = 20

(q o r)(-1) = -11

Step-by-step explanation:

Given

[tex]q(x) = -2x + 1[/tex]

[tex]r(x) = 2x^2 + 2[/tex]

Solving (a): (r o q)(-1)

In function:

(r o q)(x) = r(q(x))

So, first we calculate q(-1)

[tex]q(x) = -2x + 1[/tex]

[tex]q(-1) = -2(-1) + 1[/tex]

[tex]q(-1) = 2 + 1[/tex]

[tex]q(-1) = 3[/tex]

Next, we calculate r(q(-1))

Substitute 3 for q(-1)in r(q(-1))

r(q(-1)) = r(3)

This gives:

[tex]r(x) = 2x^2 + 2[/tex]

[tex]r(3) = 2(3)^2 + 2[/tex]

[tex]r(-1) = 2*9 + 2[/tex]

[tex]r(-1) = 20[/tex]

Hence:

(r o q)(-1) = 20

Solving (b): (q o r)(-1)

So, first we calculate r(-1)

[tex]r(x) = 2x^2 + 2[/tex]

[tex]r(-1) = 2(-1)^2 + 2[/tex]

[tex]r(-1) = 2*1 + 2[/tex]

[tex]r(-1) = 6\\[/tex]

Next, we calculate r(q(-1))

Substitute 6 for r(-1)in q(r(-1))

q(r(-1)) = q(6)

[tex]q(x) = -2x + 1[/tex]

[tex]q(6) = -2(6) + 1[/tex]

[tex]q(6) =- 12 + 1[/tex]

[tex]q(6) = -11[/tex]

Hence:

(q o r)(-1) = -11

Answer:

a. Probability = 0.15

b. Probability = 0.3

Step-by-step explanation:

Given

[tex]P(Bedroom) = 0.4[/tex]

[tex]P(Kitchen) = 0.1[/tex]

[tex]P(Bathroom) = 0.2[/tex]

[tex]P(Living\ room) = 0.15[/tex]

Solving (a): Probability of being somewhere else

This is calculated by subtracting the sum of given probabilities from 1.

[tex]Probability = 1 - (0.4 + 0.1 + 0.2 + 0.15)[/tex]

[tex]Probability = 1 - 0.85[/tex]

[tex]Probability = 0.15[/tex]

Solving (b): Probability of being in bedroom or kitchen

This is calculated as:

[tex]Probability = P(Bedroom) + P(Kitchen)[/tex]

[tex]Probability = 0.2 + 0.1[/tex]

[tex]Probability = 0.3[/tex]

Shifts 4 units down ---> [tex]g(x)=2x-10[/tex]

Stretches f(x) by a factor of 4 away from x-axis--->[tex]g(x)=8x-6[/tex]

Shifts f(x) 4 units right---> [tex]g(x)=2x-14[/tex]

Compress f(x) by a factor of 1/4 toward the y-axis ---> [tex]g(x)=1/2x-3/2[/tex]

Step-by-step explanation:

We are given [tex]f(x)=2x-6[/tex]

We need to match the transformations.

1) shifts f(x) 4 units down.

When function f(x) shifts k units down the new function becomes f(x)-k

In our case

[tex]g(x)=2x-6-4\\g(x)=2x-10[/tex]

So, Shifts 4 units down ---> [tex]g(x)=2x-10[/tex]

2) Stretches f(x) by a factor of 4 away from x-axis

When function f(x) is stretched by a factor of b away from x-axis the new function becomes f(bx)

[tex]g(x)=2(4x)-6\\g(x)=8x-6[/tex]

So, Stretches f(x) by a factor of 4 away from x-axis--->[tex]g(x)=8x-6[/tex]

3) Shifts f(x) 4 units right

When function f(x) shifts h units right the new function becomes f(x-h)

[tex]g(x)=2(x-4)-6\\g(x)=2x-8-6\\g(x)=2x-14[/tex]

So,  Shifts f(x) 4 units right---> [tex]g(x)=2x-14[/tex]

4) Compress f(x) by a factor of 1/4 toward the y-axis

When function f(x) is compressed by h factor of a toward the y-axis the new function becomes h.f(x)

[tex]g(x)=1/4(2x-6)\\g(x)=1/2x-3/2[/tex]

Compress f(x) by a factor of 1/4 toward the y-axis ---> [tex]g(x)=1/2x-3/2[/tex]

(Option Not given)

(If we compress f(x) by a factor of 4 towards y-axis we get g(x)=8x-24)

The distance between X(-9,2) and Y(5,-4) is 15.23 units.

The distance formula states that if there are 2 points A(x1, y1) and B(x2, y2), then the distance between the two points is given by the formula-

[tex]\sqrt{(x1-x2)^{2} + (y1-y2)^{2} }[/tex]

Here, we are given that there are 2 points- X(-9, 2) and Y(5, -4)

So here we can say that,

x1 = -9, y1 = 2

and x2 = 5, y2 = -4

Now, plugging in the values given above in the distance formula we will find XY as follows-

XY = [tex]\sqrt{(-9-5)^{2} + (5+4)^{2} }[/tex]

XY = [tex]\sqrt{(-14)^{2} + (9)^{2} }[/tex]

XY = [tex]\sqrt{196+ 81 }[/tex]

XY = [tex]\sqrt{277 }[/tex]

The square root of 277 is approximately 15.23.

Thus, XY = 15.23

Therefore the value of XY to the nearest hundredth is 15.23 units.

Answer:

An equation of the line that passes through the point (6, − 2) and is perpendicular to the line will be:

Step-by-step explanation:

We know that the slope-intercept form of the line equation is

y=mx+b

where m is the slope and b is the y-intercept.

Given the line

6x+y=2

Simplifying the equation to write into the  slope-intercept form

y = -6x+2

So, the slope = -6

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line.

Thus, the slope of the perpendicular line will be: -1/-6 = 1/6

Therefore, an equation of the line that passes through the point (6, − 2) and is perpendicular to the line will be

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = 1/6 and the point (6, -2)

[tex]y-\left(-2\right)=\frac{1}{6}\left(x-6\right)[/tex]

[tex]y+2=\frac{1}{6}\left(x-6\right)[/tex]

subtract 2 from both sides

[tex]y+2-2=\frac{1}{6}\left(x-6\right)-2[/tex]

[tex]y=\frac{1}{6}x-3[/tex]

Therefore, an equation of the line that passes through the point (6, − 2) and is perpendicular to the line will be:
