Answer – TrueA design is said to have Rotational symmetry if all its characteristics remain the same after it has been rotated about an axis lying in its plane. In other words, rotational symmetry is the quality possessed by a shape has when it looks the same after it has undergone some rotation by a partial turn about an axis lying in its plane. Rotational symmetry is also referred to as radial symmetry.
Answer:
No, this spigot doesn't fill at a faster rate.
Step-by-step explanation:
The first spigot can fill a pool with 9 gallons of water in a minute. Whereas the second spigot can only fill a pool with 8 gallons of water in a minute. Therefore, the second spigot fills at a faster rate.
The median is 12.
The arithmetic mean is 12.7
The geometric mean is 11.3
Correct answer is C.
Or check if f(0.2) = 0 to eliminate A and B.
Then check if f(-0.5) = 0 to eliminate D.
(6,7) should be the answer
