At 9:00 A. M. car A is traveling north at 70 miles per hour and is located 70 miles south of car B. Car B is traveling west at 40 miles per hour.

(a) Let (0,0) be the initial coordinates of car B in the xy-plane, where units are in miles. Plot the locations of each car at

9:00 A. M. and at 11:00 A. M.

(b) Find the distance d between the cars at 11:00 A. M.

i think the answer is b

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches

set the two equations for y equal to each other. solve for x. this will be the x-coordinate for the point of intersection. use this x-coordinate and plug it into either of the original equations for the lines and solve for y.
