$A.$ A right Riemann ${\displaystyle \underset{i=1}{\overset{15}{}}}\frac{ln(7+\frac{i}{5})}{3+(7+\frac{i}{5}{)}^2}*\frac{1}{5}$

function with $15$ rectangles approximating the net area $of$ the

$3+x^{2}on$ the interval $7,10.$

$B.$ A left Riemann sum with $15$ rectangles approximating the net area $of$ the

function $f(x)=\frac{ln(x)}{3+x^2}on$ the interval $7,10.$

$C.$ A right Riemann sum with $15$ rectangles approximating the net area $of$ the

function $f(x)=\frac{ln(x)}{3+x^2}on$ the interval $7,10.$

$D.$ A right Riemann sum with $5$ rectangles approximating the net area $of$ the

function $f(x)=\frac{ln(7+x)}{3+x^2}on$ the interval $0,1.$

$E.$ This $is$ not a Riemann sum; $to$ form a Riemann sum you need $to$ take $a$

$limitasn.$
