The statement is not true because 19*19*19= 6859. So your answer is false hope that helped.

Um they are not the same 19*19*19=6859 So yea 19*19*19 also known as 19^3 is bigger

Larry took out an 80/20 mortgage on a $225,000 home. What is the amount financed under the first mortgage? A.$45,000 B.$180,000

ryzh [129]

An 80/20 payment means 80% will be paid as mortgage and 20% will be the piggyback loan. Therefore, the mortgage will be:
0.8 x 225,000
= $180,000

The answer is B.

Given a = πr2s 360 , solve for s.

Dvinal [7]

If you would like to solve a = πr^2s + 360 for s, you can do this using the following steps:

a = πr^2s + 360
a - 360 = πr^2s
s = (a - 360) / (πr^2)

The correct result would be s = (a - 360) / (πr^2).

Which graph represents all of the solutions of

nevsk [136]

Step-by-step explanation:

Solve the inequality for b

-15b <= 45 divide both sides by -15, since you're dividing by a negative number switch the direction of the sign.

b >= -3

So, your number line is all values of b greater than or equal to -3. Since it is including -3, the circle will be filled and increase to the positive.

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

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