the distance of a car from a certain intercection after T seconds is given by d(T)=16+5T-T^2. when (that is, for which values of T) is the car 16 units away from the reference point? Choose all that apply:
A. T=0
B.T=1
C.T=3
D.T=5
E. never
Can some one explain this to me?

16 units away means that d = 16. 
Can you solve now?

So it would just be 0?

loser66 · Answer

cannot be 0

anonymous · Answer

okay im confused

loser66 · Answer

t is time, the car moves 16 units in 0 second? does it make sense?

anonymous · Answer

ohhhhhhhhh yeah okay so A. and E. are wrong right? so that leaves B, C and D to figure... okay I think I know what to do now thank you!

anonymous · Answer
