5. ### Using differentials to find an approximate formula

I have some past exams that I'm practicing before the real thing. They didn't come with answers and I'm really stumped on this one question: "The volume V of a cylinder of radius r and height h is given by V=π*r2*h. Using differentials, find an approximate formula for the percentage increase in...
6. ### simple function to decrease small numbers and increase large numbers

Hello, Say I have a set of real numbers in a range such as 0 to 1. I am looking for a function that will decrease the value of numbers toward the lower end, increase the value of numbers near the upper end, and leave values in the middle more or less unchanged. The method would need to work on...

9. ### How to verify a vector has a steady gradual increase mathematically?

I rank the values inside my vector then look to verify the values have a gradual but steady increase. Ideally if I had 10 numbers the smallest would occur first and the second smallest would rank second all the way to the 10th one having the 10th rank, i.e. happening last. However, knowing...
10. ### Interval of increase?

I have a pretty basic one here, that I feel kind of silly for not getting the answer to - any hints would be greatly appreciated! We have a number Q = x1 + y1, where x1 > 0 and y1 > 0. x1 and y1 are now increased by 20% and 30%, respectively: x2 = 1.2x1, y2 = 1.3y1. What is the...

I have made some modifications to my automobile to increase the fuel mileage. The EPA estimates my car's hwy fuel mileage (at 55 mph) to be about 39 mpg. In a recent road test at an average speed of 72.8 mph on the hwy (a 32% increase in velocity over the 55 mph the EPA tests at) I achieved 41.6...
13. ### rate of pressure increase

Okay so this one I thought was going to be more straight forward because I was given an equation that relates that which dependent upon time t. when a certain gas expands or contracts adiabatically, it obeys the law PV^1.4 = K where P is pressure, V is volume and K is a constant. At a certain...
14. ### Increase or Decrease?

If I have: k1 = (s/(n + v))(1/(1-b)) and k2 = A(s/(n+v+z))(1/(1-b)) where A >1 , 1>b>0, and s,n,v,z>0 is k1 greater than, equal to, or less than k2 ? I'm losing my mind on this one! (Crying) Any help greatly appreciated.
