To calculate the distance between two points, we can use a formula that is a variation Pythagorean Theorem. Look:

"d" represents the distance and coordinates are expressed as follows: (x, y)
Let's go to the calculations.

The answer is 12,6 u.c.
Answer:
B) 161.5 in²
Step-by-step explanation:
We can separate the kite figure into <em>two triangles, by cutting it vertically</em>.
So, we have two triangles with the area of <em>1/2*(6+13)*8.5</em>.
Since there is <em>two</em> of them, the equation of the total area is <em>2*1/2*(6+13)*8.5</em>.
Simplify: <em>1*19*8.5</em> (2 and 1/2 cancel out).
Multiply: <em>19*8.5</em> = 161.5 in²
Answer:
You can't really determine anything here, as we'd need to know also the value of F(x)! Check again if there misses anything in this question.
Answer:
Yes, one of the properties of determinants is that they are real numbers (including zero) not matrix. This if the entries of the matrix are real. Determinants can be both positive or negative numbers.
