Question

(havemercy)

Answer 1

Part 1: the function would be

h(t)= -16t^2+15t+6.5

Part 2: using the same steps it stated on the calculator

x=1.26

Part 3: by using t= -b/(2a) 15 as b and -16 as a  makes it

t= 15/32

Part 4: You then put 15/32 in for t in the equation making the maximum height

10.02

IDK IF THIS IS RIGHT BUT IVE SPENT ALL DAY ON THIS
