A rocket is fired upward from some initial distance above the ground. Its height (in feet), h, above the ground t seconds after it is fired is given by h(t)= -16^2+64t+1872

What is the rocket's maximum height?
feet

How long does it take for the rocket to reach its maximum height?
seconds

After it is fired, the rocket reaches the ground at t=
seconds

The variable in a relation who’s value depends on the value of the independent variable is called what?

Write and solve a real word problem that involves determining distance on a coordinate plane

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
