alyssa is driving to chicago, and she is traveling at 60 miles per hour. if chicago is 96 miles away, how long will it take her (in hours and minutes) to get there if she maintains her present rate of speed?

The value √10 and √15 are plotted on the number line

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) = .
