The function h defined by h(t)=(49+4.9t)(10-t) models the height, in meters, of an object t seconds after it is dropped from a helicopter. 1) Find of appropriate the time when the object hits the ground. Explain you reasoning

2) From what height is the object dropped? Explain you reasoning

your answer   is c

step-by-step explanation:

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5
