Answer:
Answer is yes
Step-by-step explanation:
Given in the picture are two circles which are congruent.
This suggests that the radii of the two circles are equal.
Also the central angle of the two circles are congruent (given)
Consider triangles ABC and XYZ,
AC =XY: AB = YZ:
Angle A = Angle X
By SAS theorem, the two triangles are congruent.
Hence BC = YZ
So yes is answer.

Answer:
180 because fifty is half of a whole so 90*2=180
Step-by-step explanation:
Answer:
The answer is C: (2x +3, 2y)
Step-by-step explanation:
When applying the dilation of a scale factor of 2, you have to apply it to both the x and y coordinate, which means you are multiplying the coordinates by 2.
Let's assume the coordinates you start with are (x, y). Apply the dilation of 2.
(x, y) -----> (2x, 2y)
Now you are moving the figure right. When moving right, this only effects the x coordinate since the x axis moves left and right. Moving right indicates you will add the number of units translated to the x coordinate.
Translation 2 units right:
(2x, 2y) -----> (2x +3, 2y)
You can find the inverse function for
.. y = (1 +e^x)/(1 -e^x)
by swapping the variables and solving for y.
.. x = (1 +e^y)/(1 -e^y)
.. x(1 -e^y) = 1 +e^y
.. x -1 = e^y*(1 +x)
.. e^y = (x -1)/(x +1)
.. y = ln((x -1)/(x +1)) . . . . . your inverse function

The orange dashed line is there to help you see the inverse function is the original function reflected across the line y=x.
