f(x)=(x-3i)(x+3i)
\\f(x)=x^2-(3i)^2
\\f(x)=x^2-9i^2
\\f(x)=x^2-9(-1)
\\f(x)=x^2+9

<span>x-intercepts of its graph

</span>f(x)=0&#10;\\(x-3i)(x+3i)=0&#10;\\x-3i=0 \Rightarrow x=3i&#10;\\x+3i=0 \Rightarrow x=-3i<span>

If the length of the minor axis of an ellipse is 6 units and the length of the major axis is 10 units, how far from the center a
Sedbober [7]

The distance from the center to where the foci are located exists 8 units.

<h3>How to determine the distance from the center?</h3>

The formula associated with the focus of an ellipse exists given as;

c² = a² − b²

Where c exists the distance from the focus to the center.

a exists the distance from the center to a vertex,

the major axis exists 10 units.

b exists the distance from the center to a co-vertex, the minor axis exists 6 units

c² = a² − b²

c² = 10² - 6²

c² = 100 - 36

c² = 64

c = \sqrt{64}

c = 8

Therefore, the distance from the center to where the foci are located exists 8 units.
