Donnie jumps straight up in the air and then lands on his feet again. His feet were off the ground for 1.5 seconds, and his feet reached a
maximum height of 1 foot off the ground. He then repeats this motion
over and over.
a) What would be the midline of the graph that models this situation?
b) What is the period of the graph that models this situation?
c) Write an equation that models this situation.
d) Using your equation in part c, how far off the ground would you
expect Donnie to be after 1 second?

The center of a circle represent by the equation (x+9)^2+(y-6)^2=10^2 (-9,6), (-6,9), (6,-9) ,(9,-6)

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
