I need help understanding complex zeros of a polynomial function. I've taken notes, I've watched videos, nothing helps. I'm lost

and have been stuck on this for a week now.

Polynomials can have REAL ZEROS or COMPLEX ZEROS. Real Zeros to a polynomial are POINTS where the graph crosses the x-axis when y=0. When we graph each function, we can see these points. Complex Zeros are the SOLUTIONS of the equation that ARE NOT VISIBLE on the graph.

Zero of 7 with a multiplicity of 3 means one factor is (x-7)^3

Zero of -1 with a multiplicity of 2 means one factor is (x+1)^2

Zero of 5 with a multiplicity of 1 means one factor is (x-5)

Multiplying, we get

f(x) = (x-7)^3(x+1)^2(x-5)

That's already in factored form so we leave it here.

A box is shaped like a rectangular prism. The length is 6.5 inches, the width is 1.25 inches, and the height is 7 inches.What is
Fantom [35]
To get you answer multiply the length and width twice. Then the length and height twice. Then the width and height twice. And add it all up.
7* 1.25= 8.75
7* 1.25= 8.75
7*6.5= 45.5
7*6.5= 45.5
6.5*1.25=8.125
6.5*1.25=8.125

Find angle D if angle B = 50
Mariana [72]
<h3>Answer:  80 degrees</h3>

============================================================

Explanation:

I'm assuming that segments AD and CD are tangents to the circle.

We'll need to add a point E at the center of the circle. Inscribed angle ABC subtends the minor arc AC, and this minor arc has the central angle AEC.

By the inscribed angle theorem, inscribed angle ABC = 50 doubles to 2*50 = 100 which is the measure of arc AC and also central angle AEC.

----------------------------

Focus on quadrilateral DAEC. In other words, ignore point B and any segments connected to this point.

Since AD and CD are tangents, this makes the radii EA and EC to be perpendicular to the tangent segments. So angles A and C are 90 degrees each for quadrilateral DAEC.

We just found angle AEC = 100 at the conclusion of the last section. So this is angle E of quadrilateral DAEC.

---------------------------

Here's what we have so far for quadrilateral DAEC

  • angle A = 90
  • angle E = 100
  • angle C = 90
  • angle D = unknown

Now we'll use the idea that all four angles of any quadrilateral always add to 360 degrees

A+E+C+D = 360

90+100+90+D = 360

D+280 = 360

D = 360-280

D = 80

Or a shortcut you can take is to realize that angles E and D are supplementary

E+D = 180

100+D = 180

D = 180-100

D = 80

This only works if AD and CD are tangents.

Side note: you can use the hypotenuse leg (HL) theorem to prove that triangle EAD is congruent to triangle ECD; consequently it means that AD = CD.
