Simplifying two expressions please help

√8y (the Y isto the sixth power) AND 1000-2/3 thank you :)-8 ^1/2 x y ^3 999 1/3

1. The graph of a system of parallel lines has no solutions.

A. Always B. Sometimes C. Never 2. Solve the following system.y = x + 3 3x + y = 19 THANK YOU. appreciate your help.-Just to clarify, the graph of a system of parallel lines NEVER has any solution

Ongoing multiplication

For my games server there is a job leveling system, there is a base wage -- Say, $10.00 -- And every time you level up it increases by 5%, then that new number increases by 5%, etc. (Example: level 0

Solving this equation 1/2In x = 2In 3

1/2 ln(x) = 2 ln(3) ln(x^(1/2)) = ln(3^2) ln(√x) = ln(9) √x = 9 . . . . . square both sides x = 81-Is it 1 / (2 ln x ) OR(1/2) ln x ? This has to be made clear.-x = 81-x=9

How do you think of those two proof on chain rule of calculus?Is it bogus or excellent proof?please be serious

please scroll down to Proof of The Chain Rule & Alternative Proof of the Chain Rule in this website and leave your comment and answer to the question(is it bogus?)(be serious!): http://www.karlscalc

If (-9,-1) is the endpoint of a line segment, and (8,14) is its midpoint- find the other endpoint

Please explain Step by Step, and show me the formula you used.-Let (x,y) be the other endpoint. ( (x + -9)/2 , (y + -1)/2 ) = (8,14) (x - 9)/2 = 8 x - 9 = 16 x = 25 (y - 1)/2 = 14 y - 1 = 28 y = 29-No

Alg.2 Trig Question! Help ASAP

If x is an angle in standard position and its terminal side passes through point (-3,2) find the exact value of sec x Please show work and explain, I dont think I have learned this yet this year s

Find ds/dt if s= (t/ 7t + 9)

10 points to the best answer! :)-assuming u mean s= ( t / (7t + 9) ) ds/dt = [ (7t + 9) * 1 - t * 7 ] / [ (7t + 9)^2 ] ds/dt = [ (7t + 9) - 7t ] / [ (7t + 9)^2 ] ds/dt = [ 7t + 9 - 7t ] / [ (7t +

Finding probability around the mean

Can someone help me understand how I can solve to find a probability at a certain standard deviation the mean?For example:How would I solve this problem?An explanation would really help! Find the pro

The probability that a leap year contains 52 mondays and 52 wednesdays is

We have : Leap Year = 366 days = ( 52 Weeks ) + ( 2 Days ). Thus we already have 52 Mondays and 52 Wednesdays. Those surplus 2 days can be : (1) Mon-Tues (2) Tues-Wed (3) Wed-Thurs (4) Thurs-Fr

Divide using synthetic division. (6x^5-4x^3+3x^2-2x+3) ÷ (x-2)=

2..|..6...0...-4...3...-2...3 .........12...24..40..86..168 ....------------------------------- ......6..12..20..43..84..171 So, (6x^5-4x^3+3x^2-2x+3) ÷ (x-2) = (6x^4 + 12x^3 + 20x^2 + 43x + 84) + 17
