Differentiate Functions of Other Bases In Exercise, find the derivative of the function.

WARRIOR [948]

Answer:

$\dfrac{dy}{dx} =\dfrac{2 x + 6}{ \log{\left (10 \right )}\left(x^{2} + 6 x\right)}$

Step-by-step explanation:

given

$y = \log_{10}{(x^2+6x)}$

using the property of log $\log_ab=\frac{log_cb}{log_ca}$ , and if c = $e$ , $\log_ab=\frac{ln{b}}{ln{a}}$ , we can rewrite our function as:

$y = \dfrac{\ln{\left (x^{2} + 6 x \right )}}{\ln{\left (10 \right )}}$

now we can easily differentiate:

$\dfrac{dy}{dx} = \dfrac{1}{\ln{10}}\left(\dfrac{d}{dx}(\ln{(x^{2} + 6x)})\right)$

$\dfrac{dy}{dx} = \dfrac{1}{\ln{10}}\left(\dfrac{2x+6}{x^{2} + 6x}\right)$

$\dfrac{dy}{dx} =\dfrac{2 x + 6}{ \log{\left (10 \right )}\left(x^{2} + 6 x\right)}$

This is our answer!

Goshia [24]

Answer: $\overline{QC}\cong\overline{Q'C'}$ and $\angle{ACQ}$ is a right angle .

Step-by-step explanation:

Given : A reflection is a transformation that maps point Q in a figure over a line, AB, such that for point C at the intersection of AB and QQ'.

We know that reflection creates a image equidistant from the line of reflection.

Thus, $\overline{QC}\cong\overline{Q'C'}$

Also in reflection , a line drawn from the point is perpendicular to the line of reflection.

Therefore, $\angle{ACQ}$ is a right angle

Plums are $3.25 for 2 pounds, i need 4 pounds. how much will it cost

olasank [31]

<u /> $\frac{3.25}{2lbs} = \frac{x}{4lbs} \\ \frac{3.25}{2} * \frac{2}{2} = \frac{x}{4} \\ \frac{3.25 * 2}{2*2} = \frac{x}{4} \\ 3.25*2 = x \\ x = 6.50$
It will cost $6.50 for four pounds of plums.

Hope this helps!
