The domain is $\boxed{x \neq n\pi}$ , where n is an integer.

This is because cot x = 1/tan(x), and if tan x = 0, then the fraction is undefined.

The range is all real numbers.

The vertex of this parabola is at (-2, 5). Which of the following could be it’s equation? A. Y=3(x+2)^2-5 B. Y=3(x-2)^2-5 C. Y=3

Mariulka [41]

Answer: C. $y=3(x+2)^{2} +5$

Step-by-step explanation:

1. You have the following equation of the parabola in Vertex form:

$y=a(x-h)^{2}+k$

Where h is the x-coordinate of the vextex and k is the y-coordinate of the vextex.

2. You know that the vertex of this parabola is at (-2, 5), then, susbtitute this point into the equation. Then, you obtain:

$y=3(x+2)^{2}+5$

3. Therefore, the answer is the option C.

Jakes map shows the distance from the bake stars cafe to the restaurant supply store as 3 centimeters. If the scale of the map i

Lapatulllka [165]

The real distance fro the shop to the store is 24 km

Solution:

Given that, Jakes map shows the distance from the bake stars cafe to the restaurant supply store as 3 centimeter

Scale of the map is 1 centimeter to 8 kilometers

Therefore, scale is:

$1\ centimeter : 8\ kilometer$

Let "x" be the real distance from the shop to the store

Then by proportion, we get,

$\frac{1\ centimeter}{8\ kilometer} = \frac{3\ centimeter}{x\ kilometer}\\\\\frac{1}{8} = \frac{3}{x}\\\\x = 3 \times 8\\\\x = 24$

Thus real distance fro the shop to the store is 24 km
