13. A catapult launches a boulder wint an upward velocity of 122 feet per second the height of the boulder (h) in feet after t s
SashulF [63]
For this case we have the following expression:
 h (t) = - 16t ^ 2 + 122t + 10
 We look for the maximum of the function, for this, we derive:
 h '(t) = - 32t + 122
 We match zero:
 -32t + 122 = 0
 We cleared t:
 t = 122/32
 t = 3.8125 s
 Then, the maximum height will be:
 h (3.8125) = - 16 * (3.2185) ^ 2 + 122 * (3.2185) +10
 h (3.8125) = 236.92 feet
 Answer:
 
It takes the boulder to reach maximum height about:
 
t = 3.8125 s
 
the boulders maximum height is:
 
236.92 feet

We shall have to use distribution here.

The number outside the parenthesis gets distribute with the numbers inside.

This is called distributive property.

We know the distributive property is

a(b+c) = a × b + a ×c

Using this property for

5(4 x+2)

= 5× 4x + 5 × 2

Now 5 times 4x = 20x

5 times 2 = 10

So we get

5(4 x+2)  = 20 x + 10

Option A) is the right answer.
