The height of a soccer ball can be modeled by the function h(t) = - 8t2 + 32t. where h(t) is the height in feet and t is the in seconds. find the time when the soccer ball reaches its maximum height 1 sec 2 sec 3 sec 4 sec

2 seconds

Step-by-step explanation:

We want to find when h(t) =0

0 = - 8t^2 + 32t

factor out a -8t

0 = -8t( t-4)

Using the zero product property

-8t = 0 and t-4=0

t = 0   and t=4

t=0  is when it is dropped and t=4 is when it lands

The maximum height is halfway in between

(0+4) /2

2 seconds

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
