A ball is thrown into the air by a baby alien on a planet in the system of Alpha Centauri with a velocity of 47 ft/s. Its height in feet after t seconds is given by y = 477 - 12t2.
a.) Find the average velocity for the time period beginning when to= 2 second and lasting for the given time.
t=.01 sec:
t=.005 sec:
t = .002 sec :
t = .001 sec:
b.) Estimate the instanteneous velocity when t = 2.

In the following diagram it is given that dec,ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2
