HELP ASAPP !! Select the correct answer.

Vika [28.1K]

Answer:

A) $I=\frac{P}{4\pi r^2}$

Step-by-step explanation:

To isolate $I$ , we need to divide both sides by $4\pi r^2$ . Therefore, the answer is $I=\frac{P}{4\pi r^2}$ .

Evaluate the spherical coordinate integral

expeople1 [14]

Rewrite the equations of the given boundary lines:

y = -x + 1 ==> x + y = 1

y = -x + 4 ==> x + y = 4

y = 2x + 2 ==> -2x + y = 2

y = 2x + 5 ==> -2x + y = 5

This tells us the parallelogram in the x-y plane corresponds to the rectangle in the u-v plane with 1 ≤ u ≤ 4 and 2 ≤ v ≤ 5.

Compute the Jacobian determinant for this change of coordinates:

$J=\begin{bmatrix}\frac{\partial u}{\partial x}&\frac{\partial u}{\partial y}\\\frac{\partial v}{\partial x}&\frac{\partial v}{\partial y}\end{bmatrix}=\begin{bmatrix}1&1\\-2&1\end{bmatrix}\implies|\det J|=3$

Rewrite the integrand:

$-3x+4y=-3\cdot\dfrac{u-v}3+4\cdot\dfrac{2u+v}3=\dfrac{5u+7v}3$

The integral is then

$\displaystyle\iint_R(-3x+4y)\,\mathrm dx\,\mathrm dy=3\iint_{R'}\frac{5u+7v}3\,\mathrm du\,\mathrm dv=\int_2^5\int_1^45u+7v\,\mathrm du\,\mathrm dv=\boxed{333}$

Please answer fast need it now like now now!!!!! 10+x<5

katrin [286]

Subtract 10 from both sides
10 + x < 5
10 - 10 + x < 5 - 10
x < -5
So the answer is x < -5, or x is less than -5. Any number less than -5 would be the solution. Hope this helps!

A cone has a height of 2.5 in. and a radius of 5 in. What is the volume of the cone? (Use 3.14 for . Round the answer to two dec

abruzzese [7]

V=(hπr^2)/3, we are given that h=2.5in, r=5, and π≈3.14 so:

V=(2.5*25*3.14)/3

V≈196.25/3 in^3

V≈65.42 in^3 (to nearest hundredth of a cubic inch)
