V = 864\pi

Step-by-step explanation:

Since one of the boundaries is y = 0, we need to find the roots of the function f(x)=-2x^2+6x+36. Using the quadratic equation, we get

x = \dfrac{-6 \pm \sqrt{36 - (4)(-2)(36)}}{-4}= -3,\:6

But since the region is also bounded by x = 0, that means that our limits of integration are from x=0 (instead of -3) to x=6.

Now let's find the volume using the cylindrical shells method. The volume of rotation of the region is given by

\displaystyle V = \int f(x)2\pi xdx

\:\:\:\:\:\:\:= \displaystyle \int_0^6 (-2x^2+6x+36)(2 \pi x)dx

\:\:\:\:\:\:\:= \displaystyle 2\pi \int_0^6 (-2x^3+6x^2+36x)dx

\:\:\:\:\:\:\:= \displaystyle 2\pi \left(-\frac{1}{2}x^4+2x^3+18x^2 \right)_0^6

\:\:\:\:\:\:\:= 864\pi

Point A is located at (0, 4) and point B is located at (−2, −3). Find the x value for the point that is 1 over 4 the distance fr
Vesna [10]

Answer: -0.5

<u>Step-by-step explanation:</u>

the x-value for A is 0.  

the x-value for B is -2.  

The total distance from A to B is -2.

\frac{1}{4}(-2) = -0.5

  A + -0.5

= 0 - 0.5

=  -0.5

Help asap! Lia can rent a van for either $90 per day with unlimited mileage or $50 per day with 250 free miles and an extra 25¢
ryzh [129]

Answer:

The unlimited mileage plan would save money for Lia from 410 miles onwards.

Step-by-step explanation:

Since Lia can rent a van for either $ 90 per day with unlimited mileage or $ 50 per day with 250 free miles and an extra 25 ¢ for each mile over 250, to determine for what number of miles traveled in one day would the unlimited mileage plan save Lia money, the following calculation must be performed:

90.25 - 50 = 40.25

40.25 / 0.25 = 161

161 + 250 = 411

Therefore, the unlimited mileage plan would save money for Lia from 410 miles onwards.
