    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)

    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
