Answer:

<h2>30.</h2>

Step-by-step explanation:

We know that:

h(x)=5(x-2)

When the problem asks for the value of h(8), it's actually asking for the value of the <em>h </em>function when <em>x = 8.</em> To find out, we have to replace <em>8</em> for the <em>x </em>and solve.

h(x)=5(x-2)\\x=8\\h(8) = 5(8-2)\\h(8)=5(6)\\h(8)=30

Therefore the value of <em>h(8) </em>is 30.

A pilot can travel 450 miles with the wind in the same amount of time as 360 miles against the wind. Find the speed of the wind
Lunna [17]

Given:

A pilot can travel 450 miles with the wind in the same amount of time as 360 miles against the wind.

Pilot's speed in still air is 315 miles per hour.

To find:

The speed of the wind.

Solution:

Let the speed of wind be x miles per hour.

Speed with wind = 315+x miles per hour

Speed against wind = 315-x miles per hour

We know that,

Time=\dfrac{Distance}{Speed}

According to the question,

\dfrac{450}{315+x}=\dfrac{360}{315-x}

Divide both sides by 90.

\dfrac{5}{315+x}=\dfrac{4}{315-x}

By cross multiplication, we get

5(315-x)=4(315+x)

5(315)-5x=4(315)+4x

5(315)-4(315)=4x+5x

(5-4)315=9x

Divide both sides by 9.

\dfrac{(1)315}{9}=x

35=x

Therefore, the speed of wind is 35 miles per hour.

What is the volume of the cylinder below radius 7 height 4
Veseljchak [2.6K]

V = pi * r^2 *h

where r is the radius and h is the height of the cylinder

V = pi * 7^2 *4

V = pi* 49*4

pi is approximated by 3.14 or 22/7

V = 22/7 * 49 * 4

V = 616 units ^3
