His horizontal distance D(t) (in m) from the center (where being behind the center means a negative distance)
as a function of time t (in seconds) can be modeled by a sinusoidal expression of the form a cos(b. t) + d.
Att = 0, when he pushes off, he is 1 m behind the center, which is as far back as he goes. The swing reaches
the center a seconds later.
Find D(t).
t should be in radians.

the aswere is the one with all 8's and the second one is with the 10,8 and 6

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.
