Let's simplify them top to bottom.

6(x + 2) < x - 3
6x + 12 < x - 3
5x + 12 < -3
5x < -15
x < -3
This one checks out.


3 + 4x <= 2(1 + 2x)
4x + 3 <= 4x + 2

This is a problem. In no world is 4x + 3 ever less than or equal to 4x + 2. This one has no solution.

The graph of F(x), shown below, resembles the graph of G(x) x2, but it has
Bingel [31]

Correct answer is: F(x)=-x^2-3

Step-by-step explanation:

We are given a function:

The graph of is also shown in the given question figure.

It is a parabola with vertex at (0,0).

Sign of is positive, that is why the parabola opens up.

General equation of parabola is given as:

Here, in G(x), a = 1

Vertex (h,k) is (0,0).

As seen from the question figure,

The graph of F(x) opens down that is why it will have:

Sign of as negative. i.e.

And vertex is at (0,-3)

Putting the values of a and vertex coordinates,

Hence, the equation of parabola will become:

Sin(x2 + y2) da r , where r is the region in the first quadrant between the circles with center the origin and radii 2 and 5
sweet [91]
Converting to polar coordinates gives

\displaystyle\iint_R\sin(x^2+y^2)\,\mathrm dA=\int_{\theta=0}^{\theta=\pi/2}\int_{r=2}^{r=5}\sin(r^2)r\,\mathrm dr\,\mathrm d\theta
=\displaystyle\pi\int_{r=2}^{r=5}2r\sin(r^2)\,\mathrm dr
=\displaystyle\pi\int_{r^2=4}^{r^2=25}\sin(r^2)\,\mathrm d(r^2)
=-\cos(r^2)\bigg|_{r^2=4}^{r^2=25}
=\pi(\cos4-\cos25)
