Evaluate the given integral by making an appropriate change of variables, where R is the region in the first quadrant bounded by
Whitepunk [10]

\displaystyle\iint_R\sin(384x^2+486y^2)\,\mathrm dA

Notice that Given that R is an ellipse, consider a conversion to polar coordinates:

\begin{cases}x(r,\theta)=\frac r8\cos\theta\\y(r,\theta)=\frac r9\sin\theta\end{cases}

The Jacobian for this transformation is

J=\begin{bmatrix}\frac18\cos\theta&-\frac r8\sin\theta\\\frac19\sin\theta&\frac r9\cos t\end{bmatrix}

with determinant \det J=\frac r{72}

Then the integral in polar coordinates is

\displaystyle\frac1{72}\int_0^{\pi/2}\int_0^1\sin(6r^2\cos^2t+6r^2\sin^2t)r\,\mathrm dr\,\mathrm d\theta=\int_0^{\pi/2}\int_0^1r\sin(6r^2)\,\mathrm dr\,\mathrm d\theta=\boxed{\frac{\pi\sin^23}{864}}

where you can evaluate the remaining integral by substituting s=6r^2 and \mathrm ds=12r\,\mathrm dr.

What is the equation in point slope form of the line that passes through the points (2,4) and has a slope of 3
Ronch [10]

The formula for point slope is:

y-y1=m(x-x1)

m is your slope: 3; plug in 4 for y1 and 2 for x1

y - 4=3(x-2)

According to the official M&amp;M website, 24% of the plain milk chocolate M&amp;M’s produced by Mars Corporation are blue. Anni
Delicious77 [7]

Answer:

d. Both have the same chance because they are both random samples.

Step-by-step explanation:

Regardless of the size of the candy bag, there is no way to elaborate over 40% of blue m&ms when we don't even know how many are inside each bag. the 24% is based on the company production and it does not mean that a bigger or smaller bag will have an increase in blue m&m's.
