The radius is half the diameter. So the diameter is 14.
That you and her have a 50% chance of winning.
Let
x-------> the number of persons in the family
f(x)------> the function represent the cost of living
we know that
The domain of the function would only include positive integers, because the number of persons can not be negative or a fraction
The range of the function would only include positive numbers, because the cost can not be negative
therefore
<u>the answer is the option B</u>
The domain would only include positive integers.
The coordinates of the point after the two reflections are (0.3,-7/10).
<h3>What is the reflection?</h3>
A reflection is a mapping from an isometric hyperplane with a set of fixed points acting as the reflection's axis or plane from a Euclidean space to itself. A figure's reflection creates its mirror image of that figure in the plane or axis of the reflection.
Given that, the point (-0.3, 7/10) is reflected over the y-axis and then over the x-axis respectively.
The coordinates of the point after the reflection in the y-axis are:
(0.3, 7/10)
Now, the coordinates of the point after the reflection in the x-axis are:
(0.3, -7/10)
Hence, the coordinates of the point after the two reflections are (0.3,-7/10).
