A 0.075kg tennis ball is loaded into a 2.6kg homemade cannon. The cannon is at rest when it is ignited. Immediately after the cannon recoils backwards at 4.5 m/s. Determine the magnitude of the velocity of the tennis ball after being released from the cannon.

a) what number, when added to negative four, is equal to negative five?

step-by-step explanation:

560

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.
