Answer:
Point slope form : 
Slope intercept form: 
Standard form : 
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
and
, then the equation of line is

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


The point slope form of the line is
.


Add 3 on both sides.


Therefore the slope intercept form of the line is
.
Multiply both sides by 2.


Therefore, the standard form of the line is
.
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

Step-by-step explanation:
Looks like

The solid described by
is the interior of the region bounded by the paraboloid
and the plane
. Call this region
.
By the divergence theorem,

The divergence is

so that the surface integral reduces to

or in cylindrical coordinates,

Step-by-step explanation:
1:4 bcos u need to divide both sides by 4
