Ahmad tutors history. For each hour that he tutors, he earns 40 dollars. His earings, E (in dollars), after tutoring for h hours is given by the following function. E (h) = 40h

How much does Ahmad earn if he tutors for 3 hours?

Ahmad earns 120 dollars if he tutors for 3 hours.

Step-by-step explanation: In the question, it states that, “For each hour that he tutors, he earns 40 dollars. Our question tells us to multiply by 3. 40 x 3 = 120 dollars.

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
