Can you guys help me workout these problems for my HW due tonight - sooner the better please :)

1. 1.431^9t = 3

2. At sea level, the weight of the atmosphereexerts a pressure of 14.7 pounds per square inch, commonly reffered to as 1 atmoshphere of pressure. As an object descends in water, the pressure P ad depth d are linearly related. In sal water, the pressure at a depth of 33 ft is 2 atms, or 29.4 pounds per square inch.

A) What is the correct linear model?

P = ?d + ?

B) What is the pressure at a depth of 50 ft

C) What is the depth at which the pressure is 5 atms?
