Ok it seems that im really stuck on this one question, I know how to these types of problems I just don't know what is the next step to complete the problem, can someone plz help me?

Given f(x)= square_root_of (x) , evaluate

lim ( f(x+h)-f(x) ) / h
h-->0


This is as far as i get:

( square_root(x+h) - square_root(x) ) / h

I need to get rid of the "h" ... what do i do next???

Canyou plz tell me if i got these problems correct, bc my friend here sais i didnt, but i dont think he is right...help lpz?

#1
lim ( square_root(6-h) - square_root(6) ) / h
h-->0

#2
lim ********** absolute_value( x + pi ) / ( x + pi )
x--> -pi

#3
lim ( (1/(5-x)) - (1/5) ) / x
x-->0


Ok, for the problem #1 and #2 my answer is that the limit does not exist and for #3 the limit is 1/25 . Can you tell me if these answers are correct OR show me how to do them if they are wrong? thx so much!

If you have a 21-day ascending linear regression trendline (slope .211) with an R2 of .642 with values currently two standard deviations below it, and you have a descending 7-day linear regression trendline (slope -.245) with an R2 value of .852, with values on and around it, how are these two trendlines likely to reconcile themselves? I'm interested in learning how to make these judgments. Thanks in advance.

2.(4x+9)(3x-5)
3.m2 - 81
m+9 m+9
4.factor 25x2y4 - 64x4y4
5.2x - y= -1
x + y= 7....On this one do you match up like terms??

There is a rectangular object in which the left vertical side is 1.4inches, the top horizontal side is 1.86 inches, the right vertical side is 0.83 inches, and the bottom horizontal side is unknown. Is it possible to figure out what the the unknown side is with only this information? No angles are given or any other info.

I'm trying to solve this partial fraction integral, int:10/((x-1)(x^2 +9)) dx
I wrote that A/(x-1) + (Bx+C)/(x^2+9)= 10/((x-1)(x^2 +9))
I multiplied across the equation by (x-1)(x^2+9) and got
A(x^2 +9) + (Bx+C)(x-1) = 10 Then I multiplied the left side of the equation out and got..
Ax^2 +9A + Bx^2 -Bx + Cx -C = 10 Then I set up a system of linear equations like this
A +B = 0
-B +C = 0
9A -C = 10
Now I'm stuck.. I may have made a mistake somewhere, but in any case I'm not sure how to solve this system of linear equations. What should I do?

A man of 40 dies. He leaves 3 sons and 17 camels. No camels are pregnant. His will decrees the 12 year old gets 1/2, the 13 year old gets 1/3, and the 19 year old gets the remaining 1/9. 1/2 = 9, 1/3 = 6, 1/9 =2. 9+6+2 = 17. So why was it even?
