Find the zeros of the polynomial function and state the multiplicity of each.
zheka24 [161]
\bf f(x) = 4(x + 7)^2(x - 7)^3\implies 0 = 4(x + 7)^2(x - 7)^3
\\\\\\
0=(x+7)^2(x-7)^3\implies 
\begin{cases}
0=(x+7)^7\\
\qquad 0=(x+7)(x+7)\\
\qquad -7=x\\
\qquad -7=x\\
----------\\
0=(x-7)^3\\
\qquad 0=(x-7)(x-7)(x-7)\\
\qquad 7=x\\
\qquad 7=x\\
\qquad 7=x
\end{cases}

the -7 is found there twice, so it has a multiplicity of 2
the +7 is there thrice, so it has multiplicity of 3

If a starting number is 30 and it falls to 11 what % decrease is that?
jonny [76]

Answer:

The question would've given you to what number you should round up your answer.

Answer is:

Whole number:

63%

1 decimal place:

63.3%

2 decimal places:

63.33%

Exact number:

\frac{190}{3}%

Step-by-step explanation:

So the starting no. = 30

Ending no. = 11

In order to evaluate the percentage of decrease we:

(Ending number/starting number) * 100

So:

\frac{11}{30} *100 = \frac{11}{3} *10 = \frac{110}{3}%%

To find the Decrease percentage:

100 % - 110/3 %

= 63.333%
