I'm not really sure what your problem is with me. I'm not even sure why you said yet again. The other problem I posted was not one I couldn't solve. I merely wanted to see other people's solutions to it. I just posted it in the wrong place and forgot about it. In fact, i'm fairly certain...
Not exactly, n would be 6 because your interest is counted every 2 months .
Also, you have to use the n with the exponent too. After that plug and chug and solve for t. You might have to use logs.
I guess what you want is a simple compound interestformula
A = P ( 1 + r/n ) ^nt
Amount is equal to princple times 1 plus rate divided by number of times interest is compounded per year to the numbver of times interest is compounded per year times time.
PLug in your values and solve for t
Let a=b a=c
27<_(a + a + a)^2((1/a^2) + (1/a^2) + (1/a^2))
27<_(9a^2)(3/a^2)
27<_27
So that proves that an acute triangle that happens to be an equilateral triangle is true, that means I just have to show that the rest hold true.
Well, here is where i'm at. Well, I am fairly certain that this equation is true. If we exam the smallest acute triangle I can think of, an equilateral triangle whose sides are all one, then the solutions comes out to be exactly 27. So, that is where i am at right.
I am a beginner at trying to prove or disprove inequalities. In an attempt to improve on this skill I found some problems that I would like to work on. Now, I know many of you may be able to look at this and think of a solution, but please refrain from posting it, but some advice and methods...
I like using my caclulator. I know I will make a mistake if I do not use it. My mind works beyond the step i'm doing a lot of times and I confuse numbers. I find that the calculator is a helpful tool. I am not going to sit and waste time by doing calculations that a calculator can do. I...
You use several different calculators? T-83 and beyond can switch from degrees to radians.
Anyway, the best way to know which to use is by context. If the variables in the problem deal with degrees, use degrees, if they are just constants, use radians.
