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 – 16t^2 a.) Find the average velocity for the time period begining when t = 2 and lasting for the given amount of time.

0.5 seconds.

0.1 seconds.

0.01 seconds.

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

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

a. is correct
