Check the picture below.

\bf V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=12.5\\ h=7 \end{cases}\implies V=\pi (12.5)^2(7) \\\\\\ V=1093.75\pi \implies V\approx 3436.12

Answer:

3,434.375

Step-by-step explanation:

First you change the diameter to radius by dividing 25 by 2 which gives you 12.5.

Second the formula for finding the volume of a cylinder is 3.14 x radius squared x height. So all you have to do is plug in the numbers so your equation is...

3.14 x 12.5^2 x 7 = 3,434.375

Danika concludes that the following functions are inverses of each other because f(g(x)) = x. Do you agree with Danika? Explain
arsen [322]
We cannot agree with Danika. Why? Well, The reasoning is given as follows:

Two functions are inverses of each other if and only if it is true that the composition function is given by:

f(g(x))=x

Everything is ok up to this point, right?. But let's prove that this is not fulfilled for these functions, then:

f(x)=\left | x \right | \\ \\ g(x)=-x \\ \\ f(g(x))=\left| -x \right |=\left | -1 \right | \left | x \right |=\left | x \right |  \\ \\ \therefore f(g(x))=\left | x \right | \neq x
<span>
As you can see we did not obtain the function that matches the definition of </span>inverse functions. For that reason <em>we can't agree with Danika</em>.

Rick buys remote control cars to resell. He applies a markup of 21%. Enter two expressions that represent the retail price of th
11111nata11111 [884]

The two expressions that represent the retail price of cars is: Retail price = 1.21c and Retail price = c + 0.21c

<em><u>Solution:</u></em>

Given that,

Rick buys remote control cars to resell

He applies a markup of 21%

Let "c" be the original price of remote control cars

To find: Expression for retail price of car

We know that,

Retail price = original price + markup

Here, markup price = 21 % of original price

Markup price = 21 % of c

Therefore, substituting the given values we get,

Retail price = c + 21 % of c

\text{ Retail price } = c + 21 \% \times c\\\\\text{ Retail price } = c + \frac{21}{100} \times c\\\\\text{ Retail price } = c + 0.21c\\\\

This can also be expressed as,

\text{ Retail price } = c + 0.21c = 1.21c

Thus two expressions that represent the retail price of cars is: Retail price = 1.21c and Retail price = c + 0.21c

Two similar circles are shown. The circumference of the
statuscvo [17]

The circumference of the smaller circle is [\frac{2\pi}{3} ]x \ units.

The given parameters:

  • Radius of the larger circle = x
  • Radius of the smaller circle = ¹/₃ x

The circumference of the smaller circle is calculated as follows;

C = 2\pi r\\\\C = 2\pi (\frac{x}{3} )\\\\C = [\frac{2\pi}{3} ]x \ units

Thus, the circumference of the smaller circle is [\frac{2\pi}{3} ]x \ units.
