Find a number you can multiply by the bottom of the fraction to make it 10, 100, or 1000 and multiple both top and bottom by that number then write down just the top number putting the decimal point in the correct spot.

Nathan launches a water balloon vertically from a platform on his roof. The height of the balloon (in feet) is represented by th
bulgar [2K]

Answer:

45.27feet

Step-by-step explanation:

Given the height of the balloon (in feet) represented by the equation h=−16t2+28.7t+32.4, where t is the time (in seconds)

Note that the velocity of the balloon at maximum height is zero, hence;

v = dh/dt =0

-32t+28.7 = 0

-32t = -28.7

t = 28.7/32

t = 0.897secs

Get the maximum height

Recall that h=−16t²+28.7t+32.4

h = -16(0.897)²+28.7(0.897)+32.4

h= -12.87+25.74+32.4

h = 45.27feet

Hence the maximum height reached is 45.27feet
