hammer [34]

$5x-5(6\cdot7x)=65\\\\5x-5(42x)=65\\\\5x-210x=65\\\\-205x=65\qquad\text{divide both sides by (-205)}\\\\x=-\dfrac{65}{205}\\\\x=-\dfrac{65:5}{205:5}\\\\\boxed{x=-\dfrac{13}{41}}$

Use the method of cylindrical shells to find the volume V generated by rotating the region bounded by the given curves about the

ipn [44]

For each $x$ in the interval $0\le x\le2$ , the corresponding shell has radius $x+9$ (horizontal distance from $x$ to the rotation axis) and height $8-x^3$ (vertical distance between $y=8$ and $y=x^3$ ). A shell of radius $r$ and height $h$ has area $2\pi rh$ , so the volume is

$\displaystyle2\pi\int_0^2(x+9)(8-x^3)\,\mathrm dx=2\pi\int_0^272+8x-9x^3-x^4\,\mathrm dx=\boxed{\frac{1176\pi}5}$
