8. part a: find the value of x. a. x=2 b. x=3 c. x=4 d. x=6 8. part b: in the previous question, what is the distance from a side of the triangle to the incenter? a. 23 units b. 15 units c. 11 units d. 7 units if someone could me, i would very much appreciate

Can anyone me with 32,33,36,37,and 40.

Prove (a) cosh2(x) − sinh2(x) = 1 and (b) 1 − tanh 2(x) = sech 2(x). solution (a) cosh2(x) − sinh2(x) = ex + e−x 2 2 − 2 = e2x + 2 + e−2x 4 − = 4 = . (b) we start with the identity proved in part (a): cosh2(x) − sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 − sinh2(x) cosh2(x) = 1 or 1 − tanh 2(x) = .

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.
