Cade throws a baseball from a starting height of 6 feet, with an initial velocity of 22 feet per second. Which of the following equations shows the path of the baseball? H(t) = −16t^2 + 6t + 22 H(t) = −16t^2 + 22t + 6 H(t) = −16t^2 + 28t H(t) = −16t^2 + 28

OpenStudy (lochana):

oh this is easy. H(0) must be 6

OpenStudy (lalaland_lauren):

I'm not sure tbh, I'm not very good with all this. Could you explain it to me?

OpenStudy (lochana):

yes

OpenStudy (lochana):

I am assuming 't' is the time and H(t) is the height of the ball for a given 't'. So it says that the ball starts its motion from 6 feet of height .

OpenStudy (lochana):

doesn't matter what the velocity is

OpenStudy (lochana):

it is clear that initial height is 6

OpenStudy (lochana):

start means t=0

OpenStudy (lochana):

just put 0 for t, and one takes 6 is the answer:)

OpenStudy (lalaland_lauren):

but which of the choices is the answer? because you say six is the answer but it's not clear to me

OpenStudy (lochana):

ah yes. So think about 2nd one

OpenStudy (lochana):

if put 0 for each 't' , it is something like H(0) = -16(0)^2 +22(0) + 6

OpenStudy (lochana):

solve it. will get 6

OpenStudy (lalaland_lauren):

OHHHHHHH okay

OpenStudy (lalaland_lauren):

I uderstand it now xD

OpenStudy (lochana):

bye

OpenStudy (lalaland_lauren):

OpenStudy (lochana):
