Patricia is studying a polynomial function f(x). Three given roots of f(x) are -11-square root 2i, 3 + 4i, and 10. Patricia conc

Tresset [83]

In order for the polynomial to be a degree of 4, it must have exactly 4 roots. According to the fundamental theorem of algebra: "The number of roots in a function is equivalent to the degree of the function"

These roots do not have to be real numbers, which means they can be imaginary or complex.

In this case, (-11 - √2i), (3 + 4i), and 10. There are three roots, which means that the polynomial can be a third of fourth degree polynomial. It is wrong for Patricia to assume that this is a fourth degree polynomial when only three roots are known.

<h3>The degree of the polynomial will at least be three, but could be higher.</h3>

Kite WXYZ is graphed on a coordinate plane. What is the approximate perimeter of the kite? Round to the nearest tenth. 10.6 unit

Archy [21]

Answer-

Perimeter of the kite is 16.2 units

Solution-

As WXYZ is a kite, so two disjoint pairs of consecutive sides are congruent, i.e WX=XY and WZ=ZY

So, perimeter of the kite WXYZ is,

$=2(\overline{WX}+\overline{WZ})$

And

$\overline{WX}=\sqrt{(1-3)^2+(1-4)^2}=\sqrt{(-2)^2+(-3)^2}=\sqrt{4+9}=\sqrt{13}$

$\overline{WZ}=\sqrt{(1-3)^2+(1+3)^2}=\sqrt{(-2)^2+(4)^2}=\sqrt{4+16}=\sqrt{20}$

So, perimeter will be,

$P=2(\sqrt{13}+\sqrt{20})=16.15\approx 16.2\ units$

-2(x-3)^3(x-3)^2(x+1) find both the x and y intercepts. I have found the x intercepts: -1,2,3 but am struggling to find the y in

fgiga [73]

$\bf -2(x-3)^3(x-3)^2(x+1)=0\impliedby x-intercepts
\\\\\\
x=
\begin{cases}
3\\
-1
\end{cases}$

now, the (x-3) is there 5 times, namely (x-3)(x-3)(x-3) and (x-3)(x-3), that simply means, the root of 3 has a multiplicity of 5, is all

to get the y-intercepts, simple, when the graph touches the y-axis, "x" is zero, thus $\bf -2(0-3)^3(0-3)^2(0+1)=y\impliedby y-intercepts
\\\\\\
-2(-3)^3(-3)^2(1)=y\implies -2(-27)(9)(1)=y\implies 486=y$
