The radius of the circle is given to be r = 14.5
Let the center be O. So OB is the radius = 14.5
We can draw a triangle as shown in the image below. We have a right angled triangle. We know the hypotenuse and the base, we need to find the perpendicular side. This can be done using the Pythagorean theorem.
So, we can write:

Thus, the measure of OA = 10.5
OB = OA + AB
14.5 = 10.5 + AB
⇒
AB = 4
Answer:
Step-by-step explanation:
This isn't the same thing although you will get some factors that have i in them
(x^4 - 64) factors using the difference of squares.
(x^2 - 8)(x^2 + 8) Both of these factor using the difference of squares.
(x^2 - 8): factors into (x + sqrt(8) )(x - sqrt(8) )
(x^2 - 8): factors further (x + 2*sqrt2)(x - 2sqrt(2)
(x ^2 + 8) : (x + sqrt(8)i ) (x - sqrt(8)i )
(x^2 + 8) : (x + 2sqrt(2)i) (x - 2sqrt(2)i)
Final answer
(x + 2*sqrt2)(x - 2sqrt(2)(x + 2*sqrt2)(x - 2sqrt(2)
(3j, 3k) and (3/j, 3k)
So if their x values have the same signs and their y values have the same signs, they are in the same quadrant.
If j is negative, both 3j and 3/j would be negative. If j is positive then both 3j and 3/j are positive.
And 3k is the same as 3k.

Explanation:
This is a self-answering question: you solve it by graphing the equations.
<em>The solution is where the lines intersect</em>. The point of intersection of the lines is the point that satisfies all the equations for the lines, hence is a solution to the system. If they do not intersect, there are no solutions. If the lines are coincident, there are an infinite number of solutions.

The equations can be graphed by any of a number of methods. (My favorite is to let a graphing calculator do it.) The method of choice depends on the coefficients and the form the equations are given in. Methods of graphing are a topic for a more lengthy discussion.
