I really dislike long simplification times 4 questions so I will jsut put the answers on some of them
1. remember that the denomenator cannot equal zero so find what values will and restrict them
the answer is the third one or

2. second one
(3x-2)/(5x)
3. what you would do is factor the top and divide factors making ones
answer is the fourth one or

4. find the LCM of the denoemators
4x and 2
4x=2 times 2 times x
2=2
LCM=4x
answer is the third one or 4x
ANSWERS:
1. third
2. second
3. fourth
4. third
Answer:
5 hours
Step-by-step explanation:
So what you have to do is set the two equal to one another and solve for x
50+36x=35+39x
-35 -35
15+36x=39x
-36x -36x
15= 3x
/3 /3
5=x
Answer:
The square root of 121 is 11, the square root of x^2 is x, the square root of y^3 is y and sqrt y, the square root of z^4, is z^2:
11xyz^2 sqrt(y)
Your answer is C
Note: If something is inside a radical, it is raised to an exponent of 1/2. You can rewrite anything inside the radical as raised to 1/2.
Answer:
A and C
Step-by-step explanation:
B has a domain connected to many other ranges which makes a relationship but confuses the whole function making it incorrect.
For answer D, the x coordinates 1 and 3 both have two y coordinates. That again makes a relationship but confuses the function making that answer incorrect.
In answer A, no domain is repeated in any of the points making it a function.
In answer C, again no domains are paired with more than one range making it a function. That why A and C are the answers
U2(x,t) = e^-k(w2^2)tcos(w2x)
= e^-0.046tcos(0.2x)
w2 = 0.2, w2^2 = 0.04
-0.046t = -k(w2^2)t
-0.046 = -k(0.2)^2
-0.046 = -k(0.04)
1.15 = k
