What is the multiplicity of each of the roots of the graph of f(x)=−-x^3+2x^2+3x?

DerKrebs [107]

Answer:

A. -1, multiplicity 1; 0, multiplicity 1; 3, multiplicity 1.

Step-by-step explanation:

Let $f(x) = -x^{3}+2\cdot x^{2} + 3\cdot x$ , to determine its roots and multiplicities we proceed to factorize the polynomial:

1) $-x^{3}+2\cdot x^{2} +3\cdot x$ Given

2) $x\cdot (-x^{2}+2\cdot x + 3)$ Distributive property

3) $x\cdot (x-3)\cdot (x+1)$ Quadratic formula/Result

The roots and multiplicities of $f(x) = -x^{3}+2\cdot x^{2} + 3\cdot x$ are:

0 (multiplicity 1)

3 (multiplicity 1)

-1 (multiplicity 1)

Therefore, the correct answer is A.

How do you find the circumference, radius, and diameter?

igor_vitrenko [27]

Check the picture below.

$\bf \textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=2.9 \end{cases}\implies C=2\pi (2.9)\implies C=5.8\pi \implies C\approx 18.22 \\\\[-0.35em] ~\dotfill\\\\ ~\hfill \stackrel{C\div r}{18.22\div 2.9 \approx 6.28}\qquad \stackrel{C\div d}{18.22\div 5.8 \approx 3.14}~\hfill$
