Suppose f(x,y,z) = x2 + y2 + z2 and W is the solid cylinder with height 7 and base radius 2 that is centered about the z-axis wi

kipiarov [429]

In cylindrical coordinates, W is the set of points

W = {(r, θ, z) : 0 ≤ r ≤ 2 and 0 ≤ θ ≤ 2π and -2 ≤ z ≤ 5}

(A) Then the integral of f(x, y, z) over W is

$\displaystyle\iiint_W(x^2+y^2+z^2)\,\mathrm dV = \int_0^{2\pi}\int_0^2\int_{-2}^5r(r^2+z^2)\,\mathrm dz\,\mathrm dr\,\mathrm d\theta$

(B)

$\displaystyle \int_0^{2\pi}\int_0^2\int_{-2}^5r(r^2+z^2)\,\mathrm dz\,\mathrm dr\,\mathrm d\theta = 2\pi \int_0^2\int_{-2}^5(r^3+rz^2)\,\mathrm dz\,\mathrm dr \\\\\\= 2\pi \int_0^2\left(zr^3+\frac13rz^3\right)\bigg|_{z=-2}^{z=5}\,\mathrm dr \\\\\\= 2\pi \int_0^2\left(\frac{133}3r+7r^3\right)\,\mathrm dr \\\\\\= 2\pi \left(\frac{133}6r^2+\frac74r^4\right)\bigg|_{r=0}^{r=2} \\\\\\= 2\pi \left(\frac{110}3\right) = \boxed{\frac{220\pi}3}$

Mr. Mole left his burrow that lies below the ground and started digging his way deeper into the ground,

Vedmedyk [2.9K]

Answer:

A(t) = -1.8t - 4.5

Step-by-step explanation:

Let the starting level of Mr. Mole is 'b'.

Since Mr. Mole is descending with respect to the ground, at the rate = 1.8 meters per minute

After time 't' altitude of Mr. Mole will be = b - 1.8t

If we represent the altitude of Mr. Mole with A(t).

Then the equation will be,

A(t) = b - 1.8t

Or, A(t) = -1.8t + b

At the time t = 5 minutes, his altitude was 13.5 meters.

So, -13.5 = -1.8×(5) + b

b = -13.5 + 9

b = -4.5

Now we substitute the value of b in the equation.

A(t) = -1.8t - 4.5
