Answer:
Step-by-step explanation:
The segment joining an original point with its rotated image forms a chord of the circle of rotation containing those two points. The center of the circle is the center of rotation.
This means you can find the center of rotation by considering the perpendicular bisectors of the segments joining points with their images. Here, the only proposed center that is anywhere near the perpendicular bisector of DE is point M.
__
Segment AD is perpendicular to corresponding segment FE, so the angle of rotation is 90°. (We don't know which way (CW or CCW) unless we make an assumption about which is the original figure.)
Answer:
23.274
Step-by-step explanation:
Here, rounding to the nearest thousandth means rounding to the nearest 0.001.
Hence, due to the digit being rounded having a number larger than 5 after it (0.2736), it is rounded up.
Hope this helped!

Answer:
A.0
Step-by-step explanation:
y=4x²- 9x + 9
The function will intersect the x-axis when y = 0.
4x² - 9x + 9 = 0
a=4, b= -9, c=9
D=b² - 4ac = (-9)²- 4*4*9=81 - 144= - 63
D= -63, D<0, so the equation
4x² - 9x + 9 = 0 does not have real roots. That means that function y=4x²- 9x + 9 does not intersect x- axis. So, answer is A. 0.
