Calculate the distance Tarryn drives if she drives 7/8 mile each way to and from work

Choose the point slope form of the equation below that represents the like that passes through the points (-6,4) and (2, 0)

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) = .

Solve each quadratic equation by factoring and using the zero product property. 14x - 49 = x^2
