First of all , I think you meant f(x) = 1/(x+5) the difference quotient is (f(l+h) - f(6))/h = (1/(11+h) - 1/11 )/h = (11 - 11 - h)/(11(11+h) (1/h) = -1 / (11(11+h)) I notice another error is your typing you probably meant to type: ..... can be simplified to -1/(a(h+b) ) ...

Start by converting 2 3/4 to an improper fraction. (3+2*4)/4 = 11/4 Divide 11/4 by 1/2. (11/4)/(1/2) = (11/4)*(2/1) = 11/2. Convert back to a mixed number. 11/2 = 5 1/2. The cook cannot bake half a batch of muffins. Round down to 5 batches.

math, really need some feedback asap.
5/8 x+1/16 x=11/16+x 16*(5/8 x+1/16 x) = 16(11/16+x) 10x + x = 11 + 16x, so the next step is: 11x = 11 + 16x (get x-terms on the left.) -x = 11 (divide by -1.) x = 11 Is this correct?

Square-root and squares sqrt(x) where x can be a double or float. Example: double x, out; ... out=sqrt(x); // square-root ... out=x*x; // square As far as I remember, x^2 for x-squared does not work in C++. There is math function called pow(x,2), but x*x is much simpler.
