Suppose a rocket is launched from a platform. The function h(t) = -4.9t2 + 200t + 25
gives the rocket's height, h, in meters, in terms of time, t, in seconds. The function h(t) is
equivalent to -4.9(t - 20.41)2 + 2,065.82.

step-by-step explanation:

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52

step-by-step explanation:

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
