I really need help it's due today at 2:00 1.Find the value of f(–9) and g(1) if f(x) = 8x + 6 and g(x) = 9x + 20x−2
A. f(–9) = 14
g(1) = 30

B. f(–9) = –78
g(1) = –11

C. f(–9) = –66
g(1) = 29

D. f(–9) = 8
g(1) = –80.75

2.Find the value of f(–9) and g(–1) if f(x) = –3x – 2 and g(x) = 3x3 – 24x .

A. f(–9) = 25
g(–1) = 21

B. f(–9) = –5
g(–1) = 20

C. f(–9) = 29
g(–1) = 26

D. f(–9) = 3
g(–1) = –27

The average number of vehicles waiting in line to enter a parking lot can be modeled by the function f left parenthesis x right x squared over 2 left parenthesis 1 minus x right parenthesis endfraction , where x is a number between 0 and 1 known as the traffic intensity. find the rate of change of the number of vehicles waiting with respect to the traffic intensity for the intensities (a) xequals0.3 and (b) xequals0.6.

Gravel is being dumped from a conveyor belt at a rate of 25 ft3/min, and its coarseness is such that it forms a pile in the shape of a cone whose base diameter and height are always equal. how fast is the height of the pile increasing when the pile is 14 ft high? (round your answer to two decimal places.) ft/min
