    Is there a faster way to simplify this fraction?

    I succed in simplifing this fraction, but I did this in the long way- using ax+b and mx+n. I am pretty sure there is a shorter way... what do you think?

    Working out what percentage time 1 is faster than time 2 with respect to time 2

    Hey everyone, I'm having a little difficulty with something very basic but the problem is kind of subtle and I'm really afraid of getting it wrong in my report because it's one of those mistakes one can easily miss. I programmed two versions of some code and time tested them. Let's say for...

    Whats the reason for faster convergence of 1st degree Taylor polynomial approximation

    I thought the error diminishes as we increase the terms in Taylor polynomial approximation, yet here I am trying to solve for the interest rate by defining the IRR in terms of net present value and solving for the rate in a 1st degree and a 2nd degree Taylor polynomial approximation only to...

    Simplify expression for faster calculation

    Is there any way to simplify the expression below? I want to calculate it many times in real time so speedier is better. What I really want is m, but it cannot be solved for, so I use a numerical method. The simplification I can think of is to calculate recurring parts of the expression only...

    Faster way to work out multiples

    Hi all, my fractions are not great to be honest but here is my question. Using addition, solve for a and b: 4a-6b=15 6a-4b=10 So I find a common multiple of b, I choose to use 24. 16a-24b=60 36a-24b=60 Now I go ahead and do the addition: 16a-24b=60 -36a+24b=-60 I'm left with: -20a=0 ==...

    Percentage Faster?

    Assume I do something in 20 seconds, and that is 1.25 times faster than normal. How would I find the normal time? Also, if 20 seconds is the normal time and I need to find out what 1.25 times faster would be. Thanks!

    Is there a faster method to solve this?

    Me and my friend are new to linear algebra (we posted earlier, thanks for the help) and we're a little confused on another question here: How do we solve this with that big scary exponent hanging around in the corner there? Doing it manually would take ages, is there some specific method...

    Faster way ?

    I'm having trouble finding the broken down parts of B 15u2-29u+12 | A= 15 B= -29 C= 12 | _x_= A x C = 180 | _+_=b= -29 no what i've been doing is breaking down A x C to it's prime, then I try and find what + what = B is there a easier faster way to do this? the small numbers are easy, but...

    [Kinematics] Faster way?

    I know how to do it, but it's ridiculously long. How do I do this the fast way, assuming there is one. I found the area of all and removed the negative areas to get the distance. \frac{\text{distance}}{\text{time}} And correctly got A.

    A linear graph problem

    Ok, so, there is a question I need to have answered before Tuesday afternoon. I am at 5th grade of high school now. As in the title I will post the problem and its solution. I am seeking a second and shorter way to solve this. There is! another way, cause our teacher told us. I have been trying...

    Logic Word Problems-need a faster method!

    Hey. this is on the Kaplan book page 135 A vending machine dispenses gumballs in a regularly repeating cycle of 10 different colors. If a quarter buys 3 gumballs, what is the minimum amount of money that must be spent before 3 gumballs of the same color are dispensed? The correct answer is...

    I need a faster way of doing this

    finding actual roots. Right now I'm using the Rational Root Theorem to list all the possible roots for this polynomial equation. Though it is to slow. I was wondering if anyone knew a faster way of doing this: 26.) 10x^3-49x^2+68x-20=0

    Who is faster???

    Paul & john leave city A for City B at the same time. After reaching City B, both return to city A immediately. Paul travels from A to B @ 56kmph and returns @ 64kmph. John travels @ 60kmph both ways. Who gets back to A first? (i) Paul (ii) John (iii) Both Arrive at the same time (iv)...
