Sandra wants to evaluate 2 cot her work is shown below. what did she do wrong?

The first option.

Step-by-step explanation:

1. To solve this exercise you need to remember that:

- An even function is a function with the following property:

f(-x)=f(x)

- An odd function  is a function with this property:

f(-x)=-f(x)

2. By definition, the contangent is an odd function, therefore you have that:

cot(-θ)=-cot(θ)

Then:

3. So, you can coclude that the first step is wrong. Therefore, the answer is the first option.

5/12, or 5: 12

step-by-step explanation:

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right
