Aball is dropped from the top of a 550 ft. building. the function h\left( t \right) = - 16{t^2} + 550h(t)=−16t2+550 models the height of the ball, h(t) (in feet), at any given time, t (in seconds). how long does it take the ball to reach the ground?

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

if you are saying purchasing 3 social media ads and one newspaper ad counts as one purchase then there are:

6 purchases

if you are asking how many of each then:

18 social media ads

6 newspaper ads

could you provide figure.

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
