Answer:
A= 153.94 mm
Step-by-step explanation:
A = πr²
A=π(7)²
A= 153.94 mm
Step by step:
x(2)−3x+14
=2x+−3x+14
Combine Like Terms:
=2x+−3x+14
=(2x+−3x)+(14)
=−x+14
Answer:
=−x+14
For some reason I could only find one... sorry!
Hope I could help thou! :)
Answer:
Step-by-step explanation:M angel 7 = 60 degrees, angle 1 is 60 as well because it is vertical. So your answer is A: 60. I hope my answer helped you. ;).

-175
Step-by-step explanation:
512-432=80
52+12=64
75+-100=-175
Answer:
Option A and C have rotational symmetry.
Step-by-step explanation:
The graph of odd functions have rotational symmetry about its origin.
Here the first graph is a graph of f(x)=
which is an odd function bearing an exponent of 3.
A function is "odd" when we plug in any negative value in
then it gives negative of
.
And we also know that when a graph is mirroring about the y-axis then it is an even functions.
For even functions we have reflection symmetry rather than rotational symmetry.
The second graph is a graph of
which is an even function as we can see that its graph is mirroring about the y-axis.
The third graph is a graph of an ellipse which is possessing rotational symmetry.
The order of symmetry of an ellipse is generally 2.
Order of symmetry:
The order of rotational symmetry of an object is how many times that object is rotated and fits on to itself during a full rotation of 360 degrees.
So graph A and C have rotational symmetry.
