anonymous one year ago Use upper and lower sums to approximate the area of the region using the given number of subintervals (of equal width). (Round your answers to three decimal places.) y = sqrt(6x)

what interval? what number of intervals?

0 - 1 4 rectangles

oh now we can do it

each base has length $$.25$$ lower endpoints are $$\{0,.25,.5,.75\}$$

6. anonymous

so left hand one will be $\left(\sqrt{6\times 0}+\sqrt{6\times .25}+\sqrt{6\times .5}+\sqrt{6\times .75}\right)\times .25$

and a calculator

8. anonymous

right hand one is similar, but the $$\sqrt{6\times 0}$$ will be gone, and replaced by $$\sqrt{6\times 1}$$
