A ball is thrown in the air from the top of a building. Its height, in meters above ground, as a function of time, in seconds, is given by . h(t)=-16t^2+56t+30 1. How high is the building? Explain how you know this.
2.How many seconds does it take to reach maximum height?
3What is the maximum height?

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)
