A truck enters a stretch of road that drops 4 meters in elevation for every 100 meters along
the length of the road. The road is at 1,300 meters elevation where the truck entered, and the
truck is traveling at 16 meters per second along the road. What is the elevation of the road, in
meters, at the point where the truck passes t seconds after entering the road? correct answers
1,300 − 0.64t
What is the correct expanded version of this equation?
(s-t)(s/t) correct answers (s^2/t)-s
p(x) = 3(x2 + 10x + 5) − 5(x − k). In the polynomial p(x) defined above, k is a constant. If
p(x) is divisible by x, what is the value of k? correct answers −3
In the xy-plane, if the parabola with equation y = ax2 + bx + c, where a, b, and c are
constants, passes through the point (−1, 1), which of the following must be true? correct
answers a − b + c = 1
