8, that is the same as saying what divided by 4 is 2, and 8 divided by 4 is 2. Thus, 2 is 1/4th of 8.
x^2 + y^2 - 6x - 4y - 12 = 0
x^2 - 6x + y^2 - 4y = 12
x^2 - 6x + 9 + y^2 - 4y + 4 = 12 + 9 + 4
(x - 3)^2 + (y - 2)^2 = 25
Answer:
Greatest would be Chlorine Krypton Argon Fluorine and least Hydrogen
"Inverse of an exponent?" Unsure of what you mean. Do you want to find the inverse of an exponential function?
Suppose y = 2e^x. Find the inverse function:
1. Interchange x and y: x = 2e^y
2. Solve this for y: ln x = ln 2 + y, so y = ln x - ln 2, or y = ln (x/2) (answer)
