Answer 9

The upward velocity, v, of the water in a fountain is 28 more than the product of -32 and t, where t is the number of seconds after the water leaves the fountain. As the water moves upward, its velocity decreases until it reaches the top where the velocity is zero.

A. Write an equation to represent this.



B. How long does it take for the water to reach maximum
height? (v = 0)

Answer 10

can you help with this please please !?

Answer 11

1. The perimeter of a rectangle is 78 cm. The length is 3 greater than twice its width. Find the dimensions.

Answer 12

One angle of a triangle is 2 more than four times as large as the other angle. The third angle is three times the first angle decreased by 6. What is the measure of each angle?
first angle


second angle third angle

Answer 13

for the perimeter one divide by 2 to get 39 then since a number is 3 times greater than a different number doubled do 3*2=6 so its six times greater

Answer 14

thanks !
