On a coordinate plane, point A is at (3, 3) and point B is at (negative 3, 3). Point B is the image of point A when A is rotated
90° counterclockwise around the origin. Point B must be the same from the origin as point A.
1 answer:
Answer:
Point B must be at the same distance from the the origin as point A.
Step-by-step explanation:
Coordinates of point A = (3, 3)
When point A is rotated 90° counterclockwise around the origin, coordinates of the new point B will be (-3, 3)
Distance from origin to point A =
Similarly, distance of point B from the origin =
Therefore, distances of both the points from the origin are same.
Point B must be at the same distance from the the origin as point A.

<h3>What is exponents and powers?</h3>
Exponent refers to the number of times a number is used in a multiplication. Power can be defined as a number being multiplied by itself a specific number of times.
9*(15)³/45 * /9
= 3²* 3³*5³/5² * 3² * 3² * 5
=
= 3*1
=3

Answer:
Step-by-step explanation:
Multiply out in order to find out which expression it is equivalent to.
1) Since the whole quantity is squared, write it out as .
2) Multiply binomials by using the FOIL method. Multiply the terms that are listed first in each binomial, then the ones that are listed outermost when looking at both binomials, then innermost, and finally the last terms listed in each binomial. Simplify and combine like terms.
3) , so
must be
. Thus,
is equivalent to -1. Knowing this, simplify and combine like terms.
Thus, it is equivalent to .
