is -2+3x=2x^2

-2x^2+3x-2=0 in standard form? I believe it is but I do quadratic and its no solutions so not X intercept but just want to double check I did the standard form right. Thanks.

Okay so I have to find the square root of 5376.
If you absolutely CAN'T find that one what would 1344's be.
And it can't be a decimal it has to simplified. Like 2 then a square root symbol and then 5 (for example)

Basically, does the sqauring cancel out the square root, or does the "no negative square roots" rule still aply?

i have 200 q's to do this summer. and im stuck on these 5. i have no one to consult with except you bright and intelligent people. please help...
#1. a) evaluate (1 + i)^2, where i = Squareroot(-1)
b) prove, by mathematical induction, that (1 + i)^(4n) = - 4^n, where n € N
c) hence or otherwise, find (1+ i)^32

#3. the variables x,y,z satisfy the simultaneous equations....
x + 2y + z = k
2x + y + 4z = 6
x - 4y + 5z = 9
where k is a constant.
a) (I) show that these equations do NOT have a unique solution.
(II) find the value of k for which the equations are consistent (that is, they can be solved).
b) for this value of k, find the general solutions of these equations

#5. solve the equation l e^(2x) - ( 1/ (x+2) ) l = 2
#4. the ratio of the fifth term to the twelfth term of a sequence in an arithmetic progression is 6 / 13. If each term of this sequence is positive, and the product of the first terms and the third term is 32, find the sum of the first 100 terms

The Solutions says EBIT = 250,000

Can someone show me how to do this
I know its simple algebra, but im having a dumb moment

Okay, we didn't have time in class today to get to this section but have to do the homework. The question is...

In each case (I'm gonna give 2) write the following angles between 0 and (pi/2) inclusive or between 0 degrees or 90 degrees, as appropriate. For example, sin (5pi/4) = -sin (pi/4).

I do not understand what this is actually wanting me to do. Two of the problems are...

a) sin (3pi/2) Would that be -sin (pi/2) ???


b) sin 300 degrees. I have no idea


If you know any websites, that may be better than just giving the answer. Thanks

I'm pretty embarrassed about not knowing the answer to this right off the bat. But it is the first day of school, so I suppose this is forgivable. Anyway:
Two cars leave Springfield at noon and travel in opposite directions. If one car travels r mi/h and the other travels 1.5 times as fast, how far apart are the cars at 4:00 p.m.? Give the answer in simplest form in terms of r.
Please help me and explain how this is done so I will have something to base further studies of distance problems off of. Thank you.
