I would advise you stay with MarkFL's posts However, consider another way such as this: Rewrite the integrand as: x^2(36x^2 -...

Let's look only at the numerator of the difference quotient I wrote: \frac{1}{(x+h)^5}-\frac{1}{x^5} Combining terms, we get...

Hello, and welcome to FMH! :) Let's begin with the definition of the derivative: f'(x)\equiv\lim_{h\to0}\frac{f(x+h)-f(x)}{h} In this...

Yes, rounding error is an interesting possibility here; if the potatoes were both actually 29.5 pounds and the scale rounds to the...

The standard way to solve this is with algebra (as Jomo did - but check for a sign error!); but since you put this under Arithmetic...

Your equations as per DrP: C = C_0 + cY Y = \frac{C_0+I+G}{1-c} Your variables make my head spin... I'd change them, as example: a...

You are (with a typo fixed) given this: C = C_0 + cY Y = \frac{C_0+I+G}{1-c} Here's the substitution, with an extra step or two shown...

I used to have similar questions. I once did a experiment with a simple circuit. I knew the source potential and the current in the...

Instead of asking for the thread to be deleted, why not follow Dr. Peterson's suggestion to post the relevant equation(s) you've...

Confused students don't analyze, like you do. The exercise could be better presented. As far as writing exercises that contain relevant...

Let M = how much money Minah has Let Y = how much money Yati has M-60 = Y +60 5(M-220) = Y + 220

Here's a picture of what you need. The little triangle "xz_" (I forgot to label the rightmost point) and the big triangle "xwy" are...

Would be clearer if stated this way: s = Selling price = ? c = Cost price = 6.00 p = Profit = .05 d = Deductions (.20 VAT + .15 fees) =...
