Step-by-step explanation:

you substitute the given values in s-row for s in the function, then calculate the results and fill the blanks in f(s)-row

s=0 --> f(s) = |0-2| / (0-2) = -1

s=1 --> f(s) = -1

s=9/2 --> f(s) = 1

s=11/2 --> f(s) = 1

s=6 --> f(s) = 1

In fact, there's a more shorter way to do this

You see that:

|x-2| = x-2 when x≥2

|x-2| = -(x-2) when x<2

Therefore:

f(s) = 1 for all x≥2

f(s) = -1 for all x<2

Why does the fact family for 81 and 9 have only two number sentences

Julli [10]

It only has two number sentences because 81 divided by anything else wont work only 9 would. Also since 9 times 9 is equal to 81

I will use fancy gold and red wrapping paper for two packages i have to wrap. I will use 1 2/4 yard of paper for one of the boxe

Allisa [31]

Well you need first 1 2/4 of a yard. Then you will need 5/6 of a yard. But first you need to put them together. So we need to find the common denominator. Six and four both share which multiple? Twelve. So let's rewrite that. You need 1 6/12 yards + 10/12 yards of wrapping paper. But before we do anything else we need to fix the mixed number. 1 6/12 isn't as easy to add ad 18/12 is. So 18/12 + 10/12 = 28/12
That can simplify as well. Now it's 14/6 which is equivalent to the fraction we had before. But it can also go down to 2 2/6. Now we can simplify it even further. By dividing it by two we can get 2 1/3. These are the measurements we need. So you would need how many thirds? Seven. (2 1/3 is seven thirds) This is your final answer.

You would need to have seven peices of wrapping paper cut to wrap both gift boxes.

Right triangle abc has one leg of length 6 cm, one leg of length 8 cm and a right angle at

Sauron [17]

Answer:
side length of the square = 10 cm

Explanation:
The attached image shows a diagram representing the scenario described in the problem.
Taking a look at this diagram, we can note that the side length of the square is equal to the hypotenuse of the right-angled triangle
Therefore, we can get the side of the square by calculating the length of the hypotenuse using Pythagorean theorem as follows:
(hypotenuse)² = (length of first leg)² + (length of second leg)²
(hypotenuse)² = (8)² + (6)²
(hypotenuse)² = 64 + 36
(hypotenuse)² = 100
hypotenuse = √100
hypotenuse = 10 cm

This means that the length of the side of the square is also 10 cm

Hope this helps :)
