Answer:
B
Step-by-step explanation:
-t²+4t+5=0
t²-4t-5=0
t²-5t+t-5=0
t(t-5)+1(t-5)=0
(t-5)(t+1)=0
t=5,-1
when t=0,d=5
actual time it it is in air=5-1=4 seconds.
It will be 2/5 ft long and 7/25 ft wide. 200•1/500=2/5
140•1/500=7/25

the +1 is because the y intercept is not at (0, 0), it's at (0, 1)
I graphed it and got the same graph :)
