The table shows the temperature (y) at different altitudes (x). This is a linear relationship. Find the y−intercept for this relationship.
Altitude (ft), x 0 2,000 4,000 6,000 8,000 10,000 12,000
Temperature (°F), y 59 51 43 35 27 19 11
The y−intercept for this relationship is b = ???
Please help me! Thank you!

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) = .
