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?
Ok soo... I was given an example to go off of for the class on number 1... it was this: 6^2x-x^2 = 6^-8... So i took away 6 on either side... I was left with 2x-x^2=-8... Then i did +8 to make the equation equal to zero... Then i got 2x-x^+8=0.. Then I got my answer of x = -2 and x = 4... I get that... But i dont get what you do when you have unequal numbers on either end...
The second one... I am not sure whether its P = .445d + 14.7 OR P = .445d + 29.4
Trust me... I am not a moron to post on here the actual questions... And no reason to give me a warning as I know what I am doing..
If I'm correct, what you are saying you've done is this:
This looks a tad funny, but let's go with what it looks like and continue:
Your next step says: "So i took away 6 on either side" which would give:
And your next line is incorrect.
What I would do is to expand the original, giving
Not the result you seem to be working with. Let's validate this stage before we do any more on it.
I never start with the assumption that anyone is a moron. But we are not a homework solving help site. We absolutely cannot tolerate doing someone's homework and the loss of reputation that this site has been able to garner. That would be the end of any credibility of this site. I am reeeealy stretching it by even making comments about your work. I will allow indirect help on these problems, but only this once.
