The graph shows the vertical displacement y, in centimeters, that a weight bouncing from a spring would achieve if there were no friction, for a given number of seconds, x.

( picture below !! )

(a) What is the weight’s maximum displacement?

(b) From its resting position, how long does it take the weight to bounce one direction, then the other, and then return to its resting position?

(c) What are the period and the amplitude of the function?

(d) What is the graph’s frequency and what does it indicate in this situation?

(e) How is the weight moving during the time period x = 4 to x = 5?

1/5x+9 2/5y+7

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
