4. Fireworks are fired from the roof of a 100-foot building and travel 84 feet per second. The equation
h = -167 + 84t + 100 models the height h of the fireworks at any given time t in seconds.
What was the height of the fireworks after 6 seconds?

b

step-by-step explanation:

calculate the scale factor as the ratio of corresponding sides, image to original, that is

scale factor = = = = 1

step-by-step explanation:

5 x 14?

im new, sorry if this is wrong.

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.
