If the dimensions of the following cylinder are doubled, what factor will the surface area change by?

AVprozaik [17]

To solve this problem you must apply the proccedure shown below:
1. You have that the radius and the height of the cylinder are:
$r=8 in \\ h=6 in$
2. So, you must calculate the area:
$A1=2 \pi (r+h)$
3. Substitute the values into the formula:
$A1=2 \pi (8 in)(8 in+6in) \\ A1=703.71 in^{2}$
4. When the radius and the height are doubled, you obtain:
$A2=2 \pi (16 in)(16 in+12 in) \\ A2=2814.86 in^{2}$
5. The factor is:
$F=2814.8 in^{2}/703.71 in^{2} \\ F=4$
The answer is: B. $4

Which of the following describes the roots of the polynomial function fx) = (x+ 2)2(x-4)(x+1)3?

kolezko [41]

The roots are:

$\bullet \ x=-2 \ with \ multiplicity \ of \ 2 \\ \\ \bullet \ x=4 \\ \\ \bullet \ x=-1 \ with \ multiplicity \ of \ 3$

<h2>Explanation:</h2>

We have the following polynomial function:

$f(x) = (x+2)^2(x-4)(x+1)^3$

The roots of any polynomial functions are those x-values at which the function equals zero. So, in order to find the roots for this function, we set $f(x)=0$ . So:

$(x+2)^2(x-4)(x+1)^3=0 \\ \\ \\ So \ we \ have \ the \ product \ of \ some \ factors \ then: \\ \\ The \ roots \ are: \\ \\ \\ \bullet \ x=-2 \ with \ multiplicity \ of \ 2 \\ \\ \bullet \ x=4 \\ \\ \bullet \ x=-1 \ with \ multiplicity \ of \ 3$

Finally, the graph of this function is shown below and the roots are also indicated.
