Solve the problem.Suppose that the speed of a car, measured in miles per hour (mph), is monitored for some short period of time after the driver applies the brakes. The following table and graph relate the speed of the car to the amount of time, measured in seconds (sec), elapsed from the moment that the brakes are applied.
Is the slope of the graph positive or negative and is the slope constant, or does it change over time?
A. Negative, constant B. Negative, changes over time C. Positive, changes over time D. Positive, constant
The monthly cost of driving a car depends on the number of miles driven. Julia found that in October it cost her $200 to drive 300 mi and in July it cost her $350 to drive 600 mi. Express the monthly cost C as a function of the distance driven d assuming that a linear relationship gives a suitable model.
Select the correct answer. a. C = –50d+0.5 b. C = 50d – 0.5 c. C = 0.5d + 50 d. C = 2d + 50 e. C = 0.5d – 50
Solve the problem.In one study, a type of fish was exposed to a toxin. The table lists toxin concentrations in the fish after a certain number of hours. The concentration C of the toxin in the fishes' bloodstream was measured in micrograms of toxin per gram of fish after x hours of exposure. 
(i) Describe the relationship between x and C; (ii) Use regression to find a cubic polynomial function f(x) that models the data; (iii) graph C and the data; (iv) Concentrations above 30 are lethal to the fish. Determine how many hours of exposure it takes for this to occur.
A. (i) As x increases, C increases;
(ii) f(x) ? 0.38x3 - 4.35x2 + 22.97x - 33.40
(iii)
(iv) x ? 6.0 (approximately)
B. (i) As x increases, C increases;
(ii) f(x) ? 0.38x3 - 5.35x2 + 24.97x - 33.40
(iii)
(iv) x ? 9.1 (approximately)
C. (i) As x increases, C increases;
(ii) f(x) ? 0.28x3 - 5.35x2 + 22.97x - 33.40
(iii)
(iv) x ? 6.2 (approximately)
D. (i) As x increases, C increases;
(ii) f(x) ? 0.28x3 - 4.35x2 + 24.97x - 33.40
