Answer:
Yes there is a constant rate of change of 1/3.
Step-by-step explanation:
The slope stays the same the whole time therefore the ratio does not change, so it is proportional.

Answer:
choice C is correct
Step-by-step explanation:
The clockwise sequence of vertices MNO is the opposite of the counterclockwise sequence of vertices M'N'O', so it seems some sort of reflection is involved.
Length NO is 3 times length N'O', but length NM is only 7/3 times length N'M', so the figures are <em>not similar</em>. (The ratios of side lengths must be the same for the figures to be similar.)
___
Choice D includes only rigid transformations that would ensure congruence. Similar figures may also differ by a dilation factor, so C is the better choice.
A) We can use the linear approximation to estimate the amount of time it takes. We're given that the linear approximation to t at the point x = 0 is t(x) ≈ L(x) = d(1–(x/60)). If it drives 84 miles at 62 mi/hr, we'll plug 84 in for d and 62 – 60 = 2 in for x to approximate the amount of time it takes.
L(2) = 84(1 – 2/60) = 81.2 minutes
So the answer for part a is 81.2 minutes.
b) Exact time = Distance/Speed = 84/62 = 1.35 hours, which is equivalent to 1.35 * 60 = 81.3 minutes.
