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

Question 1 (50 points) your friend, taylor, missed class today and needs some identifying solutions to systems. explain to taylor how to find the solution(s) of any system using its graph. question 2 (50 points) taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. provide taylor some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)=2x+1g(x)=2x2+1
