Answer:
Below.
Step-by-step explanation:
Yes - those are 2 semicircles so their combined area = πr^2
= 3^2π
= 9π.
Since, the coordinates of the midpoint of line RS are M
.
The coordinates of endpoint R are (-2,10)
We have to determine the coordinates of endpoint S.
The midpoint of the line segment joining the points
and
is given by the formula
.
Here, The endpoint R is (-2,10) So, 
Let the endpoint S be 
The midpoint coordinate M is
.
So, 


Now, 


So, the other endpoint S is (8,0).
Answer:
I think B
Step-by-step explanation:
Answer:
A = 138 ft^2
Step-by-step explanation:
the height is 2x+9
Let x =7
The height is 2(7)+9 = 14+9 = 23
The area is l*w
A = 6*23 =138 ft^2
Answer:
-10
Step-by-step explanation:
-4 - 5 + 4 + (-5)
-9 + 4 - 5
-5 - 5 =
-10
