Anika was shown a reduction of a complex figure.
2 complex figures. side a corresponds to a side with length 35 centimeters. side b corresponds to a side with length 25 centimeters. a side with length 15 centimeters corresponds to a side with length 60 centimeters.
figures not drawn to scale.
what can anika conclude about the scale factor and missing measurements? select three options.
the scale factor is 0.60.
the scale factor is 0.25.
the length of side a is 8.75 cm.
the length of side a is 21 cm.

Prove (a) cosh2(x) β sinh2(x) = 1 and (b) 1 β tanh 2(x) = sech 2(x). solution (a) cosh2(x) β sinh2(x) = ex + eβx 2 2 β 2 = e2x + 2 + eβ2x 4 β = 4 = . (b) we start with the identity proved in part (a): cosh2(x) β sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 β sinh2(x) cosh2(x) = 1 or 1 β tanh 2(x) = .
