mountain. Find the slope of his descent to the nearest hundredth.

I know how to figure out the slope or m value but if for example y is decreasing by a rate of 4 units per 3 unit increase of x, what does it tell you about the slope and y intercept.

Thanks

1. tan (2pi/3)

2. cos^2 (-135 degrees)

3. cot (690 degrees)

4. sin (-5pi/2)

Can you please tell me how to solve it by showing me the steps?
I obviously know how to plug them into my calculator but I have to find the exact answers. No demical approximation is allowed.. help me! I'll be waiting in front of my computer.

1. y=x³=odd
2. y=x+2=neither
3. y=x²-3=neither
4. y= (1)/(x²-1)=even
5. y= (x)/(x²-1)=even
6. y=X^4=even
7. y=x+x²=odd
8. y=x+x³=odd
9. y=(1)/(x-1)=neither
10. y= (x²)/(x²-1)=even
Please tell me if it is correct or not!

Ok, the book tells me the answer is -cos(t-s), but I don't understand how they figured it. I believe it uses implicit differentiation, but I don't know how.

Thanks for your help.

I asked for help before and it really helped so thank you guys!
I want to see if I did these right:
1) lim x-->-1 (t^2+1)^3*(t+3)^5 and we had to use a limit law and state which one. I used the product rule.
I got: lim x-->-1 (t^2+1)^3 * lim x-->-1 (t+3)^5
= lim x-->-1 (t^2+1) * lim x-->-1 (t^2+1) * lim x-->-1 (t^2+1) * lim x-->-1 (t+3) * lim x-->-1 (t+3) * lim x-->-1 (t+3) * lim x-->-1 (t+3) * lim x-->-1 (t+3)
= (by pluggin in -1 for t) 2*2*2*2*2*2*2*2 = 256

2) lim x-->-1 (x^2+2x+1) / (x^4-1)
= (by factoring) lim x-->-1 (x+1)(x+1) / (x^2-1)(x^2+1)
= Then by factoring (x^2-1) = lim x-->-1 (x+1)(x-1) / (x-1)(x+1)(x^2+1)
= then canceling out the (x+1) from the top and bottom = lim x-->-1 (x+1) / (x-1)(x^2+1)
= (pluggin in -1) lim x-->-1 (x+1) / (x-1)(x^2+1) = (-1)+1 / (-1-1)(-1^2+1) = 0 / (-2)(2) = 0 / -4 = 0

1) Use both inquality and interval notation to describe the set of numbers.

Salary raises at the State University of California at Chico will average between 2% and 6.5%.


2) Rewrite the expression without using absolute value symbols.

| (square root)5 - 5/2 |


3) Replace O with <,=,> to make the statement true.

-|-5| O |-5|

These are the problems I'm really stuck on. Please help! Will give best answer.
