I think i have the right answer but I’m just double checking so can someone find out the slope intercept equation for this graph it’s multiple choice !

If 1/2 is half of 1, what is 1/2 of 2,3, and 4?

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) = .

What is the radical expression that is equivalent to the expression 27 1 over 5?
