Which equations and/or functions represent the graphed line? Select three options.

9966 [12]

Answer:

Point slope form : $y-3=\frac{1}{2}(x-2)$

Slope intercept form: $y=\frac{1}{2}(x)+2$

Standard form : $-x+2y=4$

Step-by-step explanation:

From the given graph it is clear that the line is passing through the points, (-4, 0), (-2, 1), (0, 2), and (2, 3).

If a line passes through two points $(x_1,y_1)$ and $(x_2,y_2)$ , then the equation of line is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Let as consider any two points of the line: (2, 3) and (0, 2).

The equation of line is

$y-3=\frac{2-3}{0-2}(x-2)$

$y-3=\frac{1}{2}(x-2)$

The point slope form of the line is $y-3=\frac{1}{2}(x-2)$ .

$y-3=\frac{1}{2}(x)-\frac{1}{2}(2)$

$y-3=\frac{1}{2}(x)-1$

Add 3 on both sides.

$y=\frac{1}{2}(x)-1+3$

$y=\frac{1}{2}(x)+2$

Therefore the slope intercept form of the line is $y=\frac{1}{2}(x)+2$ .

Multiply both sides by 2.

$2y=x+4$

$-x+2y=4$

Therefore, the standard form of the line is $-x+2y=4$ .

Find the area of a sector with a central angle of 170° and a diameter of 9.1 cm. Round to the nearest tenth.

Nesterboy [21]

A central angle:
α = 170°
d = 9.1 cm
r = 9.1 : 2 = 4.55 cm
Area of a sector:
A = r² π α / 360°
A = ( 4.55 )² · 3.14 · 170° / 360°
A = 30.7 cm²

Sketch the solid described by x 2 + y 2 ≤ z ≤ 1. Use the Divergence Theorem to evaluate the surface integral over the boundary o

kirill115 [55]

Looks like

$\vec F(x,y,z)=y\,\vec\imath+z\,\vec\jmath+xz\,\vec k$

The solid described by $x^2+y^2\le z\le 1$ is the interior of the region bounded by the paraboloid $z=x^2+y^2$ and the plane $z=1$ . Call this region $R$ .

By the divergence theorem,

$\displaystyle\iint_{\partial R}\vec F\cdot\mathrm d\vec S=\iiint_R\mathrm{div}\vec F\,\mathrm dV$

The divergence is

$\mathrm{div}\vec F(x,y,z)=(y)_x+(z)_y+(xz)_z=x$

so that the surface integral reduces to

$\displaystyle\iiint_Rx\,\mathrm dV$

or in cylindrical coordinates,

$\displaystyle\int_0^{2\pi}\int_0^1\int_{r^2}^1r^2\cos\theta\,\mathrm dz\,\mathrm dr\,\mathrm d\theta=\boxed{0}$
