A cone and 2 cylinders are shown below. The volume of the cone is 15 cubic centimeters. Each of the 2 cylinder has the same heig

shutvik [7]

Answer:

90 $cm^{3}$

Step-by-step explanation:

<u>Given:</u>

The volume of a cylinder =15 $cm^{3}$

Height of cone = Height of either cylinder

Radius of cone=Radius of either cylinder

<u>Formula:</u>

Volume of a cone = $\pi r^{2}h/3$

Volume of a cylinder = $\pi r^{2}h$

<u>To find: </u>Combined volume of both cylinders.

The volume of a cylinder =15 $cm^{3}$

$\pi r^{2}h/3$ =15 $cm^{3}$

$\pi r^{2}h$ =15 * 3 $cm^{3}$

$\pi r^{2}h$ =45 $cm^{3}$

[As

Height of cone = Height of either cylinder

Radius of cone=Radius of either cylinder<u>]</u>

$\pi r^{2}h$ =45 $cm^{3}$ is the volume of one cylinder.

Combined volume of cylinder = 2* Volume of cylinder = 2*45 =90 $cm^{3}$

For f(x)=2-x and g(x)=4x^2+x+6, find (f×g)(x)

Dima020 [189]

Answer:

Our composed function is $f(g(x)) = -4x^2-x-4$ .

Step-by-step explanation:

We are given two separate functions:

$f(x) = 2-x$

$g(x) = 4x^2 + x + 6$

We need to find the composition of $(f \cdot g)(x)$ . This is literally stating "f of g of x."

Therefore, we simply plug g(x) into f(x) and solve. We replace the x-value in the f(x) function with the entirety of the g(x) function and simplify.

$f(g(x)) = 2 - (4x^2+x+6)\\\\f(g(x)) = 2 - 4x^2 + x + 6\\\\f(g(x)) = -4x^2 - x - 4$

Our composed function is $f(g(x)) = -4x^2-x-4$ .

What is an equation of the line that passes through the points (4,-2) and (-1,3)

Paraphin [41]

Answer:

<h3>The slope is -1.</h3>

Step-by-step explanation:

To find an equation of the line that passes through the points, you have to use the slope formula.

Slope:

$\Rightarrow \sf{\dfrac{y_2-y_1}{x_2-x_1} }$

y2=3

y1=(-2)

x2=(-1)

x1=4

Solve.

3--2/-1-4=5/-5=-1

The slope is -1.
