Answer:
3 feet
Step-by-step explanation:
The equation with all the parameters filled in is ...
f(t) = -16t² +8t +2
The maximum height occurs at the vertex of the function, which can be written in vertex form as ...
f(t) = -16(t² -1/2t) +2
f(t) = -16(t² -1/2t +1/16) +2 +16(1/16)
f(t) = -16(x -1/4)² +3
The vertex of the graph is (1/4, 3), so the maximum height is 3 feet.

divide total miles by time:
157.5 / 2.5 = 63 miles per hour
Step 1
calculate the value for i=1
=(4*(1/2)<span> ^(1-1))---> 4
step 2
</span>calculate the value for i=2
=(4*(1/2) ^(2-1))---> 2
step 3
calculate the value for i=
=(4*(1/2) ^(3-1))---> 4*(1/4)---->1
step 4
find the sum
(4+2+1)=7
