The rocket that carried the Curiosity Rover to Mars traveled at a speed of 21,000 miles per hour. What is this speed to the nearest mile per second?

5.83 miles per second or 6 miles rounded

Step-by-step explanation:

There are 60 minutes per hour and 60 seconds per minute

60 x 60 = 3600 seconds her hour

21000/3600 = 5.83 miles per second or 6 miles rounded

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
