Answer:

The absolute value of Point B labelled on the number line is 1.6.

Step-by-step explanation:

In a number line

Coordinate of point A = -2.2

Coordinate of point B = -1.6

Coordinate of point C = 1.2

We need to find the absolute value of Point B labelled on the number line.

Absolute value : Absolute value of a real number is the non-negative value of that number. Let x be a real number, then

$|x|=|-x|=x$

The absolute value of Point B is

$|-1.6|=1.6$

Therefore the absolute value of Point B labelled on the number line is 1.6.

I need help finishing a question. I used the explanation function on the program, but it didn't specify what to do to get the fi

I would compute sqrt(1 + 160pi^2) first to get approximately 39.75093337

Add this to 1 and we have 40.75093337

Then divide over 2pi to get a final approximate result of 6.48571248

So x = 6.48571248 is one approximate solution

In short, I computed $\frac{1+\sqrt{1+160\pi^2}}{2\pi}$ only focusing on the plus for now.

----------------------

If you were to compute $\frac{1-\sqrt{1+160\pi^2}}{2\pi}$ you should get roughly -6.167402596 as your other solution. Each solution can then be plugged into the original equation to check if you get 0 or not. You likely won't land exactly on 0 but you'll get close enough.
