Which of the following describes the transformations of g (x) = negative (2) Superscript x + 4 Baseline minus 2 from the parent

o-na [289]

Answer: First option.

Step-by-step explanation:

Below are some transformations for a function $f(x)$ :

1. If $f(x)+k$ , the function is shifted "k" units up.

2 If $f(x)-k$ , the function is shifted "k" units down.

3. If $f(x-k)$ , the function is shifted "k" units right.

4. If $f(x+k)$ , the function is shifted "k" units left.

5. If $-f(x)$ , the function is reflected over the x-axis.

6. If $f(-x)$ , the function is reflected over the y-axis.

Then, given the parent function $f(x)$ :

$f(x)=2^x$

And knowing that the the other function is:

$g(x)=-2^{(x+4)}-2$

You can identify that the function $g(x)$ is obtained by:

- Shifting the function $f(x)$ 4 units left.

- Reflecting the function $f(x)$ 4 over the x-axis.

- Shifting the function $f(x)$ 2 units down.

a ladder 6m long leans against the wall of house if the foot of the ladder makes an angle 58 degree with tye ground how far is t

Vedmedyk [2.9K]

Answer:

The base of the ladder is 3.2 meters far from the wall.

Step-by-step explanation:

We need to calculate the base of a right triangle. The given information is:

h: hypotenuse = length of the ladder = 6 m

b: is the base =?

θ: is the angle between the hypotenuse and the base = 58°

To find the base we can use the following trigonometric equation:

$cos(\theta) = \frac{b}{h}$

$b = cos(\theta)*h = cos(58)*6 = 3.2 m$

Therefore, the base of the ladder is 3.2 meters far from the wall.

I hope it helps you!

Find the domain of the rational expression: x-3/2x-8

miss Akunina [59]

Answer:

$\huge\boxed{x\neq4\to x\in\mathbb{R}\backslash\{4\}}$

Step-by-step explanation:

$\dfrac{x-3}{2x-8}$

We know: the denominator must be different than 0.

Therefore

$2x-8\neq0$ <em>add 8 to both sides</em>

$2x-8+8\neq0+8$

$2x\neq8$ <em>divide both sides by 2</em>

$\dfrac{2x}{2}=\dfrac{8}{2}\\\\x\neq4$
