I need a little help and if you're good please help me asap!! I know some of you pursued kines and nutritional science so you would have had to taken math classes. I haven't taken a math class in over 1.5 years so I need a little help on a couple problems.

Please let me know I will donate :-D

Why not just link up the problems so people have an idea as to what they are? I did that college algebra freshman year of high school (I was super advanced in math), but I might still have some of it down if you link up the problems (that was 11 years ago). I would imagine unless I have completely lost those concepts all together that I would probably know how to solve them.

1-Change 1 by (u-3)/(u-3)
2-Put on common denominator
3-Simplify nominator to 2u-10/(u-3)
4-Multiply both sides by the denominator of the other one (2u-10)*(u-1) and vice versa
5-Simplify, you'll get a quadratic form =0
6-Do whatever u need to do, calculator can probably solve it, else use methods seen in class

e/ was drawing it out but my thing froze, if this isnt clear i can redraw if u want

It is kind of clear. what is your answer? I got u= -1 or 5

i didnt calc, i'll check in a minute

yep 5 or -1

e/ i just punched it into an online equation solver, you can google them to verify your answers or some give your the step by step solution

1/cosT=SQ(2)
cosT=1/(SQ2)
Answers: T=cos-1(1/SQ2)

T=teta, sq=square root

You'll get a value, you can change the sign (cos stays the same), so if u get 0.36 for example, -0.36 is also a valid answer

Can also add 2pi without changing answer, but you'll go out of the interval
