A projectile is fired vertically into the air. Its motion is described by
h = -16t2 + 320t, where h is the projectile’s height (in feet) after t seconds.

a. During what time interval(s) will the height of the projectile be below 1024 feet?
b. During what time interval(s) will the height of the projectile be above 1024 feet?

Iam trying to solve a linear equation for the shoe size of someone 84" tall taking into consideration example 1 is 69" tall with a shoe size of 9 and example 2 is 72 inches tall with a shoe size of 11. i understand that the equation should be y=mx+b and that on the graph the answer is (3,2) but i just don't understand how to create the equation to solve for 84-inches and 60-inches tall questions. after two days, i need .

Find the slope of the line below . enter your answer as a fraction or decimal. use a slash mark ( / ) as the fraction bar if necessary
