How do I do number 5?

rewona [7]

H(t)=-16t^2+15t+12
(e)
maximum height is reached when h'(t)=-32t+15=0, or tm=15/32 seconds.
maximum height reached = h(tm)=h(15/32)=-16(15/32)^2+15(15/32)+12
=993/64 ft
=15.516 ft.
(f) when Greg reaches water, h(t)=0=-16t^2+15t+12
Solve for t using quadratic formula,
t=[-15+/- sqrt(15^2+4*12*16)]/(2*-16)
=-0.516s or 1.4535s.
Reject negative root so
Greg reaches water at t=1.4535 seconds.

Sladkaya [172]

Lawn Sprinkler Time = (Hose Time * Combined Time) / (Hose Time - Combined Time)
Lawn Sprinkler Time = (8 * 5) / (8 -5)
Lawn Sprinkler Time = 40 / 3
Lawn Sprinkler Time = 13.33 minutes

********************************************
Double-Check
Total Time = (Time 1 * Time 2) / (Time 1 + Time 2)
Total Time = (8 * 13.33) / (8 + 13.33)
Total Time = 5 minutes
It is correct!!
