Question

if a fountains equation is Y=-16x^2+240x+0 how long will the water remain in the air?

Answer 1

does it really say \(+0\) at the end?

Answer 2

yes it does i guess it had to complete the right equation form

Answer 3

ok then set
\[-16t^2+240t=0\] and solve for \(t\) by factoring

Answer 4

\[-16t(t-15)=0\]
\[t=0\] or
\[t=15\] so stays in the air for 15 seconds

Answer 5

thank you so much!!
