Your formula should say V = 4/3 pi * r^ CUBED not squared
Volume = (4/3) * 3.14 * 2^3
Volume = (4/3) * 3.14 * 8
Volume = 39.433333333333
Volume = 39.43
X^2-2x-5=(x-1)^2-6
After substituting we get that the domain is:
{-6;-5}
Jon earns 6 dollars per hour.
We know this because, if he gets paid $20 and buys $2 worth of gasoline, his profit is $18.
Then, we divide 18 by the number of hours he worked, 3, and thus, Jon earns $6/hr.
