Atoy rocket launched straight up from the ground with an initial velocity of 80 ft/s returns to the ground after 5 s.
the height of the rocket t seconds after launch is modeled by the function f(t)=-16t^2+80t.
what is the maximum height of the rocket, in feet?

42

step-by-step explanation:

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
