21. Physics A ball is rolling down a slope and continuously picks up speed. Suppose
the function f(x) = 1.2(1.11) describes the speed of the ball in inches per minute.
How fast will the ball be rolling in 20 minutes? Round the answer to the nearest
whole number.

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
