Answer:

For problem 17a) your answer is: x=11.5 degrees

Step-by-step explanation:

1. Measure of angle BCA will be 180°-124°=46°

2. In triangle BCA, you now have two angles. 46 degrees, and 2x.

3. Measure of angle ABE is an exterior angle of triangle BCA

4. Using the exterior angle theorem, angle ABE=angle BCA+angle BAC

5. substitute!! 2x+46=6x

6. move 2x over and then divide by 4, you get x=11.5°

7. You can plug the answer back in to check if it correct!! have a nice day :>

Differentiating a Logarithmic Function In Exercise, find the derivative of the function.

sp2606 [1]

Answer:

$\dfrac{d(f(x))}{dx} = \dfrac{2}{x}$

Step-by-step explanation:

We are given the following function in the question:

$f(x) = \ln (3x^2)$

We have to derivate the given function.

Formula:

$\dfrac{d(\ln x)}{dx} = \dfrac{1}{x}\\\\\dfrac{d(x^n)}{dx} = nx^{n-1}$

The derivation takes place in the following manner

$f(x) = \ln (3x^2)\\\\\dfrac{d(f(x))}{dx} = \displaystyle\frac{d(\ln(3x^2))}{dx}\\\\=\frac{1}{3x^2}\times \frac{d(3x^2)}{dx}\\\\= \frac{1}{3x^2}\times (6x)\\\\=\frac{6x}{3x^2}\\\\=\frac{2}{x}$

$\dfrac{d(f(x))}{dx} = \dfrac{2}{x}$

If you divide it by 5 on both numbers you get four and three. So 4 is the answer.
