Answer from: Quest

Explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

Answer 2

The semi-trailer truck has the fastest average speed

Explanation:

Let's recall that the formula of the average speed is:

Average speed = Distance/Speed

Now, we can calculate the average speed for each class of vehicle, as follows:

Flatbed truck average speed = 144/5 = 28.8 miles per hour

Semi-trailer truck average speed = 327/4 = 81.75 miles per hour

Tanker truck average speed = 589/15 = 39.27 miles per hour

Which truck has the fastest average speed?

The semi-trailer truck has the fastest average speed
