I think it’s 36 square feet
Answer:
h(t) = -16t2 + 144
h(1) = -16(12) + 144 = 128 ft
h(2) = -16(22) + 144 = 80 ft
h(2) - h(1) = 80 - 128 = -48 ft
It fell 48 ft between t = 1 and t = 2 seconds.
It reaches the ground when h(t) = 0
0 = -16t2 + 144
t = √(144/16) s = 3s
It reaches the ground 3s after being dropped.

Answer:
325 miles
Step-by-step explanation:
$20 for each day
5 days
$0.30 for each mile
20(5) + 0.3x = 197.5
100 + 0.3x = 197.5
100 - 100 + 0.3x = 197.5 - 100
0.3x = 97.5

x = 325
Answer:
n = x * 3
Step-by-step explanation:
n is your "number"
Answer: 49 in^2
Step-by-step explanation:
Trapezoid area formula = (a+b/2) x h
So...
(5+9/2) x 7
= 49 in^2
