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.

Asix-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. in the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times. the experimental probability of rolling a 3 is 10 %, which is approximately % more than its theoretical probability. (round off your answers to the nearest integer.)

What are the triple angle formulas? is it related to double angle identities?

Anew obstacle course is home to several new types of challenging obstacles. one such obstacle is traversing a 15-stair staircase. to make it more challenging, the stairs are not uniformly spaced. rather, the vertical space between consecutive stairs for the first 10 stairs is 113 feet and the vertical space for the last 5 stairs is 134 feet. what is the total vertical distance traveled ascending and descending the entire 15-stair staircase?
