Answer: 14.32 units
Step-by-step explanation:
The formula for calculate the distance between two points is:

In this case, given the points (-2,8) and (11,2), we can identify that:

Therefore, we just need to substitute values into the formula in order to calculate the distance between the given points. This is (Rounded to the nearest hundred):

The answer is Associative
1 + 3i, - sqrt 10 would be the other two answers
4k+mn=n-3
3(4k+mn)= 12k+mn
So, 12k+mn=n
Answer:
See explanation
Step-by-step explanation:
The given trigonometric equation is
.
We take the inverse cosine of both sides to get:

to the nearest degree
None of the options satisfies the given equation.
But if the question is actually;

Then;
