Amodel rocket was launched from the top of a building. the rocket's approximate height can be modeled by the quadratic equation h = -4.9t2 + 53.9t + 127.4, where h is the rocket's height, in meters, after t seconds. when factored, this equation is h = -4.9(t - 13)(t + 2). what is a reasonable time for it to take the rocket to land on the ground?

You are looking for the x-intercepts. Only one intercept will be valid because time must be positive!

0 = -4.9(t - 13)(t + 2)

0 = -4.9 , 0 = t - 13 , 0 = t + 2

False, t = 13 t = -2 (not valid)

13 seconds

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
