-3p^3 + 5p -2p^2 - 4 - 12p + 5 + 8p^3
5p^3 - 2p^2 - 7p + 1
It is the second choice
$4.00 + $2.25* number of miles
$4.00 + $2.25* 8.7= $23.58
You have to add then subtract
Answer:
See below in bold.
Step-by-step explanation:
A). s(t)= -16t^2+64t+200
Converting to vertex form.
s(t) = -16 (t^2 - 4t) + 200
s(t) = -16 [(t - 2)^2 - 4] + 200
s(t) = -16(t - 2)^2 + 64 + 200
s(t) = -16(t - 2)^2 + 264
The maximum height is after 2 seconds and it is 264 feet.
B) The ball hits the ground when s(t) = 0 so we have:
-16t^2+64t+200 = 0
x [-64 +/- sqrt (64^2 - 4*-16*200) ] / -32
x = 6.06, -2.06
So the answer is 6.06 seconds.
