Question

If the distance covered in time t is given by s(t) = 4t2 + 3t, where s(t) is in meters and t is in seconds, what is the distance covered in the interval between 2 seconds and 3 seconds? @jim_thompson5910

Answer 1

"the distance covered in time t is given by s(t) = 4t^2 + 3t"

so the distance covered in 2 seconds is s(2) = ???
the distance covered in 3 seconds is s(3) = ???

therefore, the distance covered from 2 to 3 seconds is equal to s(3) - s(2) = ??

Answer 2

i got 41-22? for s(3)-s(2)

Answer 4

double check your work

Answer 5

you're close but not quite there

Answer 6

i keep getting to 41-22? am i missing a step?? (/__\)

Answer 7

recheck s(3)

Answer 8

it's not 41

Answer 9
