So, the x-intercept is the point (5,0). The distance between those points is
At a rate of 2 units per second, it will take seconds to travel 7.81 units. That’s about 3.91.
36 . C
Use the given angle to find the ratio of the legs:
If you call AC (the leg you’re looking for) x, then you can call leg BC 0.781x. Half the product
of the legs is the area, or 15:
37 . E
You should know what the ranges are of (A) y = sin x and (B) y = cos x. They’re both −1 ≤ y ≤ 1.
They both include −1 and 1 themselves, so you can eliminate (A) and (B). The upper limit of
(C) is 1, but (C) can be much smaller than −1, such as when x = −0.99. So you can eliminate
(C). (D) can never be less than zero because the numerator and denominator are
nonnegative for all possible x.
The answer is (E) because as x gets very large, approaches or , so the value
of the whole expression approaches 1; and as x gets very small (that is, very negative),
