U can choose more then 1

You substitute each value for t in the equation. Take t=0 for example. \[d(0)=16+5(0)-0^2=16\] So t=0 works. Do that for the rest.

I feel like nothing else works but zero just by looking at it

OpenStudy (anonymous):

o no d works as well

OpenStudy (anonymous):

SO A and D?

OpenStudy (anonymous):

Yep, just those two.

OpenStudy (anonymous):

write it in standard form and factor the expression : 16 = 16 + 5t - t^2

OpenStudy (anonymous):

yep u were right thanks :)
