Debra serves the volleyball to Vicki with an upward velocity of 10.5ft/s. The ball is 5 feet above the ground when she strikes it. How long does Vicki have to react, before the volleyball hits the ground? Round your answer to two decimal places.

What is the question that you needed answered?

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
