The relationship between the amount of data downloaded d, in megabytes, and the time t, in seconds, after the download started is shown.
Which of the following statements are true? Select all that apply.

A. The data points on the scatter plot suggest a linear association.
B. The data points on the scatter plot suggest a quadratic association.
C. The data points on the scatter plot suggest a positive association.
D. The data points on the scatter plot suggest a negative association.
E. For every second that passes, about 1 additional megabyte is downloaded.
F. For every second that passes, about 0.5 additional megabyte is downloaded.
G. The function that represents the line of best fit is approximately d(t) = 0.51t - 1.64.
H. The function that represents the line of best fit is approximately d(t) = 1.04t + 0.51.

the answer is b.

step-by-step explanation:

i believe it's a.

i'm not sure on this one, most likely correct.

step-by-step explanation:

part a. the differences are decreasing, so we know the sequence is not arithmetic. the ratios are constant (=3/4), so we know the sequence is geometric.

part b. from part a, we know the common ratio is 3/4, so each term is 3/4 of the one before. the initial term is the number of gallons at h=1.

g[h] = (3/4)·g[h-1]

g[1] = 384 . . . . initial value required for a recursive definition

part c. the general formula for a geometric sequence is

a[n] = a[1]·r^(n-1)

we have a[1] = 384, r = 3/4, and the term number given by h. the formula that follows is

g[h] = 384·(3/4)^(h-1)

part d. filling in the value and doing the arithmetic, we have

g[12] = 384·(3/4)^11 ≈ 384·0.042235136 ≈ 16.2183 . . gallons

part e. each gallon is 4 quarts, so

16.2183 gal × 4 qt/gal = 64.8732 qt

the answer for this question is a= 13,622.84
