The graph of f (x) = RootIndex 3 StartRoot x + 8 EndRoot is shown. On a coordinate plane, a cube root function goes through (negative 16, negative 2), has an inflectio point at (negative 8, 0), and goes through (0, 2).

Which statement is true?

a)The function is only increasing when x ≥ −8.
b)The function is only increasing when x ≥ 0.
c)The function is always decreasing.
d)The function is always increasing.

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.

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

you.
