Mrs. brown’s class has 4 pizzas which have same size and shape. if each pizza is cut into 8 equal slices and one slice is given to each student, how many slices of pizza will be left over after each of the 27 students gets a slice? my life is at stake here

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) = .

According to the general equation for conditional probability if p(anb)=3/7 and p(b)=7/8 what is p(a i b)

Which equation can be solved to find one of the missing side lengths in the triangle? cos(60o) = cos(60o) = cos(60o) = cos(60o) = mark this and return
