So this is equal to 529.5. And so that's our approximation for the definite integral part, but then we also have to divide it by 10, or we have to multiply it times 1 tenth. So we've evaluated, so this part right over here, we got 529.5 as our approximation. It's not going to be exact, but using the trapezoidal sum, the sum of the areas of these trapezoids, and now we have to multiply it by 1 tenth. So let's do that. Or we can just divide by 10, which actually we don't need a calculator for that, 52.95. So this whole thing evaluates to 52.95.
