Answer with Step-by-step explanation:
We are given that
u+ v and u-v are orthogonal
We have to prove that u and v must have the same length.
When two vector a and b are orthogonal then
By using the property
We know that
Magnitude is always positive
When power of base on both sides are equal then base will be equal
Therefore,
Hence, the length of vectors u and v must have the same length.
The length of the radius of circle o is 18 cm.
<h2></h2><h2>Given that</h2>
Circle o has a circumference of 36π cm.
<h3>We have to determine</h3>
What is the length of the radius, r?
<h3>According to the question</h3>Circle o has a circumference of 36π cm.
The length of the radius of the circle is determined by the following formula;
Substitute all the values in the formula;
Hence, the length of the radius of circle o is 18 cm.
