Select the factors that can be divided out to simplify the multiplication problem: 4/26 x 13/20. Select all that apply. A. 2 B.

Tcecarenko [31]

$\dfrac{4}{26} \times \dfrac{13}{20}$

-------------------------------------
Divide by factor of 4.
-------------------------------------
<em>*Or divide by the factor of 2 twice</em>

$\dfrac{1 \times 4}{26} \times \dfrac{13}{5 \times 4}$

$\dfrac{1}{26} \times \dfrac{13}{5}$

-------------------------------------
Divide by factor of 13.
-------------------------------------

$\dfrac{1}{2 \times 13} \times \ \dfrac{1 \times 13}{5}$

$\dfrac{1}{2} \times \dfrac{1 }{5}$

-------------------------------------
Combine into single fraction.
-------------------------------------
$\dfrac{1}{10}$

--------------------------------------------------------------------------
Answer: The factors are 2, 4 and 13

How do I find the critical points?

podryga [215]

Critical points is where the derivative (slope) is zero or does not exist. So to do this we have to find the derivative of our function:

$\frac{d}{dx}(x^{2} - 1)^{3}$

So we apply chain rule:

= $3(x^{2} - 1)^{2} * 2x$

Set our first derivative to zero and solve for x:

3(x^2 - 1) * 2x = 0

So we can see that (by plugging in) 0, -1 and 1 makes our solution true

So our critical value is x = 0, x = -1, x = 1
