If a ball is thrown into the air with a velocity of 40 ft/s its height in feet t seconds later is given by y= 40t−16t^2. (a) Find the average velocity for the time period beginning when t= 2 and lasting(i) 0.5 second (ii) 0.1 second (iii) 0.05 second (iv) 0.01 second (b) Estimate the instantaneous velocity when t= 2

i believe the answer is 323 ft

step-by-step explanation:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
