If a polynomial with real coefficient has a complex zero, the conjugate of that number will be a zero as well.

So, if 4-6i is a zero, 4+6i will be a zero as well

If -2+11i is a zero, -2-11i will be a zero as well

So, the zeroes are

\dfrac{1}{3},\ 4-6i,\ 4+6i,\ -2+11i,\ -2-11i

Answer:

Step-by-step explanation:

As the other helper has pointed out, the imaginary zeros occur in pairs. So the other two zeroes are 4+6i and -2-11i.

You have exatly 200 feet of fencing to enclose 2 adjacent square regions. assuming you use all the fencing provided what will th
bekas [8.4K]
Adjacent so that means 1 wall will be shared

each square has 4 sides,
but they share a side so 4+4-1=7 sides total

200 divided by 7 sides=200/7 ft per side

the area of a square is side^2
side=200/7
so area=(200/7)^2=40000/49
that's for 1 square
times 2
80000/49 square feet
about 1632.6530612244897959183673469388 square feet
rounded is 1633 square feet

What is the y-intercept of f(x)<br> -(1)?<br><br> A. (1,0)<br> B.(1 1/4)<br> C. (0,0)<br> D. (0,1)
Nataly [62]

Y intercept is where our x variable is equal to 0 and where the graph touches the y-axis.

Therefore, you can get the y intercept by just plugging in x = 0. For example, in the linear function: f(x) = 2x + 3, our y intercept would be (0,3) because we just set our x value equal to 0.

Find the volume of the cone shown as a decimal rounded to the nearest tenth.
Makovka662 [10]

Answer:

<h2> a.  392.7 yd³</h2><h2 />

Step-by-step explanation:

volume = 1/3 π r² h

where h = 15 yd.

           r = 5 yd.

<u>plugin values into the equation:</u>

volume = 1/3 π r² h

            = 1/3 * π * 5² * 15

            = 392.7 yd³
