I'll give 99 points a ball is thrown into the air with an upward velocity of 80ft/s. its height h in feet after t seconds id given by the function h= -16t^2+80t+5. what is the maximum height the ball reaches? how long will it take the ball to reach maximum height? how long does it take for the mall to be caught 5 feet off the ground? all i really need on is the last one. will some one plz me.

need points to ask question

step-by-step explanation:

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.
