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

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

step-by-step explanation: 4 cause 2+2=4
