When a football is punted, it goes up in the air, reaches a maximum altitude, and then comes back down. We can assume that the football follows a parabolic path. When the ball was kicked it was one foot above the ground. One second later, it was 20 feet above the ground. Four seconds after it was kicked it was 35 feet above the field. What is the quadratic equation?

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
