If you're meaning a value between 11 and 20, write
1120 and put a line under the < and >, which indicates that x could also equal 11 or 20. x doesnt only have to be a value between 11 and 20, but it can equal the numbers too. It could be any variable, actually, so you could do any other letter if you wanted
Answer:
a) 325.72
Step-by-step explanation:
A=4pir^2
A=4x3,14x7.2x7.2
a=651.44
1/2a=1/2x651.44
=325.72
Answer:
C. A'(3,4), B'(-1,3), C'(-1,-1)
Step by step answer:
The coordinates of the vertices are A(-3,-4), B (1,-3), C(1,1).
We have the formula for the rotating a shape at an angle of 180° which shows that you are reflecting the shape twice.
(x, y) -> (-x, -y)
So, the coordinates will be,
A(-3,-4) = A'(3,4)
B (1,-3) = B'(-1,3)
C(1,1) = C'(-1,-1)
Thank you.
Rt-2n=y -- add 2n
Rt=y+2n -- divide by R
t=(y+2n)/R
