Question

Omar throws a softball from a starting height of 8 feet, with an initial velocity of 18 feet per second. Which of the following equations shows the path of the softball?

H(t) = −16t2 + 26
H(t) = −16t2 + 26t
H(t) = −16t2 + 8t + 18
H(t) = −16t2 + 18t + 8

Answer 1

can you help?/

Answer 3

yay

Answer 4

Omar throws a softball from a starting height of 8 feet,

They are not very clear, but we have to assume "start" is at t (t for time) = 0
which equation shows the height is 8 when t= 0 ?

any idea?

Answer 5

C??

Answer 6

C H(t) = −16t2 + 8t + 18

put in 0 in place of t
what do you get ?

Answer 7

erase the "t" and put in 0 instead

Answer 8

18

Answer 9

we want 8

Answer 10

okay, ill plug in 0 for D and see what happens?

Answer 11

ok

Answer 12

yea i got 8 this time

Answer 13

yes, and for an equation that describes throwing something into the air, the number in front of the middle term
18 t
is the initial velocity

Answer 14

yay

Answer 15

can you help with one more?

Answer 16

did you post it?

Answer 17

no not yet, want me to?
