Abusiness bought 12 identical computers on sale. the original price, p, of each computer was reduced by $36.
altogether, the business paid $3888 for the computers.
which linear equation correctly models the situation?
(p—36) = 3888
12
12 (p + 36) = 3888
12 (p – 36) = 3888
pi
(p+36) = 3888
12
check answer

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) = .
