Ur not dumb!!! i graphed the line for u here. i suggest watching some khan academy videos for extra practice!
Answer:
Point
lies on
axis and point
lies quadrant III.
Step-by-step explanation:
A coordinate plane is a plane that is divided into four quadrants by the coordinate axes.
Here, coordinate axes are
axis and
axis.
Let's first mark the points in the coordinate plane.
See the attached figure.
From the figure, it can be observed that point
lies on
axis and point
lies quadrant III.
13)
Circumference (C) = 2π·r
11π = 2π·r
11/2 = r
******************************
Area (A) = π·r²
= π·(11/2)²
= 121π/4
≈ 94.985 in²
14)
diameter = 2r
42 = 2r
21 = r
*******************
Area (A) = π·r²
= π·(21)²
= 441π
≈ 1384.74 in²
***************************
$280/1384.74 in²
x = $0.20
Answer: about 20 cents per square inch
