[tex] | \sqrt \frac{3v}{\pi \: h} | = r[/tex]

The given formula for the volume of cone can be written as [tex]\sqrt{\frac{2V}{\pi h} }[/tex] in terms of V and h for r.

To bring a term from one side of an equation to the other, with corresponding change in sign or by doing opposite operations is called transposing a term in an expression.

According to the given question.

We have a formula for the volume of cone

[tex]V = \frac{1}{2} \pi r^{2} h[/tex]

To solve the the above formula for r we use transpose method.

Therefore,

[tex]V = \frac{1}{2} \pi r^{2} h[/tex]

⇒ [tex]2V = \pi r^{2}h[/tex]           (multiplying by 2 both the sides)

⇒ [tex]\frac{2V}{\pi h} =r^{2}[/tex]                (dividing both the sides by πh)

⇒ [tex]r=\sqrt{\frac{2V}{\pi h} }[/tex]

Hence, the given formula for the volume of cone can be written as [tex]\sqrt{\frac{2V}{\pi h} }[/tex] in terms of V and h for r.

B) Stratified Random Sampling will be preferred because the opinions of the staffs on the tipping policy may be the same within each type but differ across the different types of staffs.

Now, from the question, we see that after adding a 20% to the cost of food and beverages, that the additional revenue will be distributed equally among the kitchen and server staffs.

This means the strata here will be the type of staff because the opinions of the staffs on the tipping policy may be the within each type but differ across both types of staffs.

Answer:

  f^-1(x) = <see attachment>

Step-by-step explanation:

If we write the function as ...

  f(x) = ∛x +101/128x

Then the inverse function is the value of y when ...

  x = f(y)

This resolves to a cubic in y, whose solution can be found by use of any of the various cubic solution formulas. You can find the cubic by ...

  x = ∛y +by . . . . . . where b = 101/128

  x -by = ∛y . . . . . . . subtract by

  (x -by)³= y . . . . . . cube both sides

If we subtract the left side and expand the cube, we get ...

  b³y³ -3b²xy² +(1 +3bx²)y -x³ = 0 . . . . . . . a cubic in y

There will be one real and two complex solutions to this cubic. The real solution can be written in the form shown in the attachment. That is, ...

  y = f⁻¹(x) = [attachment expression]

A graph of it is shown in the second attachment. It is the reflection of f(x) across the line y = x, as an inverse function should be.

Additional comment

The idea here is to show that it is possible to write an expression for the inverse function. It is not pretty, and it is somewhat tedious to evaluate.

Answer:

2/4 or 1/2

Hope this helps!

The slope of the line that passes through (-2, -3) and (2, -1) will be 1/2.

The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.

The slope of the line is given as,

m = (y₂ - y₁) / (x₂ - x₁)

From the graph, the points are (-2, -3) and (2, -1). Then the slope of the line is calculated as,

m = (- 3 + 1) / (-2 - 2)

m = 2/4

m = 1/2

The slope of the line that passes through (-2, -3) and (2, -1) will be 1/2.

Answer:

24:8

Step-by-step explanation:

Given the following data;

Batch = eggs + sticks of butter

4 batches = 12:4

8 batches = 2 * 4 batches

Therefore, 8 batches = 2*(12:4)

8 batches = 24:8

Hence, the equivalent ratio Sierra would use if she wants to make 8 batches is 24 eggs to 8 sticks of butter.

Answer:

[tex](5.4 \times {10}^{4} ) \div (2 \times {10}^{3} ) \\ \\ \\ \frac{5.4 \times {10}^{4} }{2 \times {10}^{3} } = \frac{54 \times {10}^{4} }{20 \times {10}^{3} } \\ \\ \\ = 2.7 \times {10}^{1} \\ = 27[/tex]

Step-by-step explanation:

Answer:

36=4*9

Step-by-step explanation:

Answer:

[tex]y=-x+10[/tex]

Step-by-step explanation:

First we must know the format of slope-intercept form!

This is: [tex]y=mx+b[/tex] (where "m" is the slope and b is the y-intercept)

Given this equation: [tex]2x+2y=20[/tex]   we must convert this into the format of slope-intercept form.

First, we should move the "2x" to the other side of the equation, we do this by subtracting -2x from 2x and proceed to move it to the other side.

This would be result in: [tex]2y=-2x+20[/tex]

Next, we need to isolate the "y" variable by dividing the 2 off of it.

What you do to one side you do to the other!

-2 / 2 is -1 so this will just be "-x"

20 / 2 is 10

Therefore, our resulting equation will be: [tex]y = -x+10[/tex]

Answer:

Step-by-step explanation:

p = 2L+ 2W

length

(7-4)

3 feet

p = 2L+ 2W

146 = 2*3 + 2* w

146  = 6 + 2w

146-6 = 6-6 +2w

140 = 0+ 2w

140 = 2w

70 feet  = w

width is 70 feet

p= 2L+2W

146 = 2*a +2* 70

146 = 2a + 140

146-140 = 2a + 140-140

6 = 2a

3 feet  = a

length is 3 feet

width is 70 feet.
