Mark sits on a swing that is 2.5 feet off the ground. swinging as hard as he can, the swing reaches a height of 6 feet. assuming mark holds a steady pace, the height of the swing could be represented by a cosine curve. if mark makes a full swing forward and backward in 3 seconds, which graph below could represent the height of the swing, in feet, for any time, t?

the answer is 150.6

step-by-step explanation:

you multiply .02 by 30 and get .6.

and then you multiply 5.00 by 30 and get 150.

hope this !
