Consider the right-end Riemann sum representing the area under the graph of $$3x^2+4x$$ from 0 to 5 using $$n$$ equal subdivisions. What is $$?\mathrm{x}$$ ? (Your answer should be a function of $$n$$.) Q What is the general formula for $$x_i$$ for the Riemann sum in ferms of $$n$$ ? Q[E] What is the general formula for $$f\left(x_i\right)$$ in terms of $$n$$ ? What is the general formula for $$f\left(x_i\right)?$$ xin terms of $$n$$ ? Use the formulas $$\underset{i=1}{\overset{n}{?}}i=\frac{n(n+1)}{2}$$ and $$\underset{i=1}{\overset{n}{?}}{i}^2=\frac{n(n+1)(2n+1)}{6}$$ to compute the Riemann sum in terms of $$n$$. Compute $${?}_0^5\left(3x^2+4x\right)\mathrm{d}x$$ by taking a limit of the Riemann sum as $$n??$$.
