use whatever necessary (i.e. factoring, complete the square, quadraitc formal, etc..) to find the solutions.

A. x^6 - 64 = 0
B. 9x^4 - 24x^3 + 16x^2 = 0
C. x^4 + 2x^3 - 8x - 16 = 0
D. 36t^4 + 29t^2 - 7 = 0
E. (x^2 - x - 22)^4/3 --> as in x^2 - x - 22 is to the 4/3 power.
F. square root of x + square root of x-20 = 10
G. x^2 + 8x - 19 = 0
H. 4x^3 + 2x^2 - 24x - 12 = 0


when doing this, can you show me the work & explain how to do it?


THANK YOU SOOO MUCH!

A PC can be bought by making monthly payments of AED 125 at the end of the month for 2 years.

The first payment is usually due one month after the purchase of the PC. The Company has made a special offer for Ramadan and the first payment is due at the end of the month 2 months after the PC is purchased. The financing cost is 24% compounded monthly.

What is the purchase price of the PC?

I have to finish my summer homework and i am down to the last few and i just don't know how to finish them. And the reason i am doing it last minute is not because i am procrastinating. I have had a 9-6 job, at the Goddard School which is like a daycare/preschool, all summer to help pay for my car.

But the original math question is solve the equation:

ln x = ln (x+1) - 1 and i don't evem know where to start.

2007-08-26 05:31:43 · 11 answers · asked by webshell46 1

its equation is x2 + (y - 4)2 = 4 so do I assume it is (x-0)^2+(y-4)^2?

center is (0,4) and the R=4?
