Misha Larkins [42]

Answer:

5 months

Step-by-step explanation:

Daniel's provider charges $60 for installation and $45.95 per month. Sydney's provider has free installation and charges $57.95 per month

Let x = number of months

Daniel = 60 + 45.95x

Sydney = 0 + 57.95x

Equate both equations

60 + 45.95x = 0 + 57.95x

Collect like terms

60 - 0 =57.95x - 45.95x

60 = 12x

Divide both sides by 12

x = 60 / 12

= 5

x = 5 months

Daniel and Sydney would have paid the same amount for high-speed Internet service after 5 months

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}
