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

0.5 seconds

(ii) 0.1 seconds.

(iii) 0.01 seconds.

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

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
