If a ball is thrown straight up into the air with an initial velocity of 100 ft/s, it height in feet after t second is given by y = 100t – 16. a.) Find the average velocity for the time period begining when t = 2 and lasting for the given amount of time.

0.5 seconds

(ii) 0.1 seconds.

(iii) 0.01 seconds.

b.) Based on the above results, guess what the instantaneous velocity of the ball is when t = 2 seconds.

Solve the following simultaneous equation by using an algebraic method (either substitution or elimination) 2x + 3y=-4 4x-y=11

Rewrite so the subject can be y in the formula d=m-y/y+n
