Assume all positions refer to the center of the ball.

Dwyane Wade shoots a lot of free throws. When he lets it go, it's 15 feet from the basket, and 7 feet off the ground. When the ball reaches its maximum height, it is 13 feet high. When the ball goes through the hoop, it is zero feet from the basket and 10 feet high.

Set this problem up so that the y-axis is a line through the center of the basket, and the x-axis is a line on the floor from under the center of the basket to directly under Mr. Wade.

Find the equation of the parabola that matches the ball's trajectory.

Best answer will explain the process.

I'd like some help to prove this:

Let f_n be a sequence of monotonic functions defined on [a, b] that converges to a continuous function f. Then, the convergence is uniform.

Thank you

Based on the pattern, make a conjecture about the sum of the first 20 positive even numbers.

2 = 2 = 1.2
2+4 = 6 = 2.3
2+4+6 = 12 = 3.4
2+4+6+8 = 20 = 4.5
2+4+6+8+10 = 30 = 5.6



A. the sum is 20.21

B. the sum is 21.22

C. the sum is 19.20

D. the sum is 20.20
