point slope form of a line
y-y1 = m(x-x1)
y-7 = -2 (x-1)
if you want it in slope intercept form
y-7 = -2x +2
add 7 to each side
y = -2x +9
Answer:
172.7sqft (square feet)
Step-by-step explanation:
SA = 2(pi)(r)(h) + 2(pi)r^2
plug in the radius, height, and find SA, then multiply by 10 fenceposts.
SA= 2(3.14)(.5)(6)
Solve
SA=14.39166
Multiply by 12
Answer is 172.7sqft
Hope this helps!

Answer:</h2>
Four points are always coplanar if:
A. They lie in the same plane.
C. all of them are collinear.
<h2>
Step-by-step explanation:</h2>
<u>Coplanar--</u>
The points are said to be coplanar if all of them lie in the same plane.
<u>Collinear-</u>
The points are said to be collinear if all of them lie on a straight line.
Also as we know that a line always lie in one plane and so all the points that lie on that line will also lie in the same plane.
Hence, we may say that Four points will be coplanar if all of them are collinear.
Hence, the correct options are:
Option: A and Option: C
Answer: Option C.
Step-by-step explanation:
You need to find the distance AB with the formula for calculate the distance between two points:
Then, substituting the coordinates of the points A(1,1) and B(4,1), you get:
You know that A'B'=6, then the scale factor of dilation can be calculated with:
Substituting values, you get:
This matches with the option C.
