The Volume Of A Cylinder Is 63 Pi Cm^3 . If The Radius Is 3cm, What Is The Height Of The Cylinder?A.

Answers

Answer 1

Answer:

Step-by-step explanation:

volume = πr²h = π·3²h = 63π

h = 7 cm

Answer 2

The height of the given cylinder is 7 cm. Therefore, option D is the correct answer.

What is the volume?

Volume is the measure of the capacity that an object holds.

Formula to find the volume of the object is Volume = Area of a base × Height.

Given that, the volume of a cylinder is 63π cm³ and the radius is 3 cm.

We know that, the formula to find the volume of a cylinder is πr²h.

Now, πr²h=63π

π×3²×h=63π

h= 7 cm

Therefore, option D is the correct answer.

С

D

The equation has infinitely many solutions,

Answers

Answer:

If Step is 53 = 477 then no solution exist

If Step is 53 x = 477 then there exist a unique solution x = 9

Step-by-step explanation:

Given - Ramon solves a linear equation. One of the steps in his work is

             53 = 477

To find - Which of these describes the solution to the equation that Ramon

              solves?

Proof -

As given, One of the steps in his work is 53 = 477

There are 2 cases possible -

Case I:

If his step is 53 = 477

Then, the equation has no solution because 53 ≠ 477

Case I:

If his step is 53 x = 477

Then, the equation has a solution because x = [tex]\frac{477}{53}[/tex] = 9

⇒The equation has a solution of x = 9.

Step-by-step explanation:

First you have to plug in the points into y2-y1/x2-x1. This would make it      -2-0/0+1. Simplify this to get -2/1 which is -2. This makes the slope -2. Then plug in the slope into point intercept form y-y1=m(x-x1) where m is the slope. This time, I will use the point (0,-2). Therefore, the equation will be y+2=1(x-0) which is equal to y+2 =x-0 which is equal to y=x-2.

This is how you do all of the problems. For problem 13-15, you know that f(0)=-1 is (0,-1) and f(3)=-10 is (3,-10). Then you can solve the problems. I will not explain every single problem but will give you the answers.

What is power?

Power is the result of multiplying two numbers together. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.

The given expression can be written as,

2⁶ = 2 × 2 × 2 × 2 × 2 × 2

At a carnival booth, customers had to guess the number of jelly beans in a jar. Samantha guessed there were 375 jelly beans. The actual amount of jelly beans in the jar was 250. What is Samantha's percent error?

Answers

Answer:

150

Step-by-step explanation:

The required percent error by Samantha is 50%, as of the given condition,

What is the percentage?

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

What is the error?

Errors are discrepancies between values that are seen and natural truths.

Here,
Samantha guessed there were 375 jelly beans.
The actual amount of jelly beans in the jar was 250.
Error percentage = 375-250 / 250 × 100
                           = 0.5 × 100
                           = 50%

Thus, the required percent error by Samantha is 50%, as of the given condition.

For the function g(x) =10 x ^5/x-2, what is the inverse function?

Answers

Answer:

[tex]g^{-1}(x) =(\frac{x}{10})^{5} +2[/tex]

Step-by-step explanation:

So we have the function [tex]g(x)=10\sqrt[5]{x-2}[/tex]. To find the inverse, we first set the function equal to y:

[tex]y=10\sqrt[5]{x-2}[/tex]

Then, we switch all the y and x variables, like this:

[tex]x=10\sqrt[5]{y-2}[/tex]

Now, we solve for y to find the inverse function:

[tex]x=10\sqrt[5]{y-2}[/tex]

[tex]\frac{x}{10} =\sqrt[5]{y-2}[/tex]

[tex](\frac{x}{10})^{5} =y-2[/tex]

[tex](\frac{x}{10})^{5} +2=y[/tex]

[tex]y=(\frac{x}{10})^{5} +2[/tex]

[tex]g^{-1}(x) =(\frac{x}{10})^{5} +2[/tex]
