Need help in business calculus.  I'm not sure how to solve for a and b when given integrals. For example, upper bound: 23, lower bound: 5 ∫f(x)dx - upper bound: 14, lower bound: 5 ∫f(x)dx=upper bound: b, lower bound: a ∫f(x)dx  How would do I solve for a and b?

If a coffee filter is dropped, its velocity after t seconds is given by v(t)=4(10.0003t) feet per second. What is the terminal velocity, and how long does it take the filter to reach 99 of terminal velocity? Use a table increment of 0.1 and given your answer to the nearest tenth of a second.
