Determine the number of zeros of the polynomial function. h(t) = (t − 6)2 − (t + 6)2

Step-by-step explanation:

(t - 6)^2 = t^2 - 12t + 36

(t + 6)^2 = t^2 + 12t +36

(t - 6)^2 - (t + 6) = t^2 - 12t + 36 - (t^2 + 12t + 36)

(t - 6)^2 - (t + 6) = t^2 - 12t + 36 - t^2 - 12t - 36

(t - 6)^2 - (t + 6) = -24t    The other 4 terms cancel out.

-24t = 0   Divide by - 24

t = 0

There is one root.

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.

you already gave the answer
