Points D and E are the midpoints of their respective sides. In addition, mA = 50°, mAED=63°, and DE =17. What is the length of BC?

In what form is the following linear equation written y=9x+2

Find cot x if sin x cot x csc x = √2

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
