Answer:
Option A is correct
a reflection over the y-axis
Step-by-step explanation:
The rule of reflection over y-axis is given by:
As per the statement:
Given the transform,
(a, b) to (-a, b)
By definition of reflection;
The given transform is, a reflection over the y-axis

Answer:
The number of rotations completed by tire = 500.
Step-by-step explanation:
The diameter of the tire of toy car = 8 cm
Now, DIAMETER = 2 x RADIUS
So, radius of the tire = D/2 = 8/2 = 4 cm
Now, Circumference of the Circle = 2πr
= 2 x 3.14 x 4 = 25.12 cm
Now,
=
The number of rotations completed by circle = 500.
