Question 13 of 15 • MO-Algebra II A
A bicycle path starts 5 miles due east of an intersection, and continues in a straight line to finish 8 miles due north of the same intersection. Let the intersection be represented by the point (0, 0). Suppose a cyclist rides the path from start to finish in 2 hours. Which parametric equations model the path of the rider?
Answer
A
x (t) = negative five-halves t + 5 and y (t) = 4 t
B
x (t) = negative five-halves t + 5 and y (t) = 4 t + 8
C
x(t) = 5t + 2 and y(t) = 8tD
x(t) = 5t and y(t) = 8t + 2
