Answer:
Option (A)
Step-by-step explanation:
A set of real numbers is a combination of both rational and irrational numbers.
But the elements in the sets of rational and irrational numbers will be different.
In short, rational and irrational number sets are the two subsets of real numbers.
Hence, the number is an element of either the set of rational numbers or the set of irrational numbers.
Option (A) is the correct option.
Given the center (a,b) and the radius r, the equation of the circle is
Plug your values a = -6, b = -3, r = 12
Answer:
90° counter clockwise rotation of point 0(x, y) about origin = (-y, x)
Step-by-step explanation:
Following are the rules for a counter clockwise rotation of 90 degrees about the origin for a point O(x,y):
1. Invert the sign of the value of y.
2. Switch x and y with each other.
For example, a point A(5,2) after rotation gives a point B(-2,5) using the rules given above. The points on the x-y plane are shown in the image attached.
