During a scuba dive, Lainey descended to a point 21 feet below the ocean surface. She continued her descent at a rate of 21 feet per minute. Enter an inequality you could solve to find the number of minutes she can continue to descend if she does not want to reach a point more than 84 feet below the ocean surface. Use t to represent the variable for the minutes Lainey can continue to descend.

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

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. david estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x.
