Question

help please..

Answer 1

the \(x\) axis between 2 and 6 is divided in to 8 intervals each of length \(\frac{1}{2}\)

Answer 2

your rather tedious job is to compute the area of each of these rectangles

Answer 3

how so?

Answer 4

the base is \(\frac{1}{2}\) and the height is the value of the function at the left hand endpoints, namely
\[2,2.5,3,3.5,4,4.5,5,5.5\]

Answer 5

your job is to compute
\[f(2)\times \frac{1}{2}+f(2.5)\times \frac{1}{2}+f(3)\times \frac{1}{2}+f(3.5)\times \frac{1}{2}\]\[+f(4)\times \frac{1}{2}+f(4.5)\times \frac{1}{2}+f(5)\times \frac{1}{2}+f(5.5)\times \frac{1}{2}\]

Answer 6

or more simply put
\[\left(f(2)+f(2.5)+f(3)+f(3.5)+f(4)+f(4.5)+f(5)+f(5.5)\right)\frac{1}{2}\]

Answer 7

whats is the function equation?

Answer 8

\(f(x)=\frac{x^2}{9}\)

Answer 9

have fun, use a calculator, wolfram or a spread sheet

Answer 10

yes thank you, for the next one ( underestimate)

Answer 11

actually a spread sheet is easiest
gotta run

Answer 12

ok thank you
