Question

The area bounded by the parabola $blank y to the power of 2 end exponent equals 4 x blank$ with the lines x=1, x=9 is

$\frac{436}{15}$
$\frac{208}{3}$
$\frac{236}{5}$
$\frac{340}{13}$

The correct answer is: $fraction numerator 208 over denominator 3 end fraction$

$y to the power of 2 end exponent equals 4 x comma blank x equals 1 comma blank x equals 9$
$R. A equals 2 not stretchy integral from 1 to 9 of 2 square root of x d x$
$equals 2.2. fraction numerator 2 over denominator 3 end fraction open parentheses x to the power of 3 divided by 2 end exponent close parentheses subscript 1 end subscript superscript 9 end superscript$

$equals fraction numerator 8 over denominator 3 end fraction open parentheses 27 minus 1 close parentheses$
$equals fraction numerator 8 over denominator 3 end fraction open parentheses 26 close parentheses$
$equals fraction numerator 208 over denominator 3 end fraction$
