Answer: The information in that "9" is the atomic number of the atom.
Step-by-step explanation:
For an atom of fluorine we have:
A = atomic weight = 18.99 amu.
Z = atomic number = 9.
(A - Z) = number of netrons = 10.
Then the "9" in the information of the atom of fluorine gives information about the atomic number.
Each friend gets $25.50 for only distributing the flyers but, they all have $10.20 worth of copies printed each so, if you want to find out the total amount of money he is really wasting on one friend including the copy money it is $35.70
For this question you need to be familiar with the basic shapes of odd and even functions; looking at the graphs, we can see that the first two are clearly odd functions and the second two are even functions.
For odd functions, an easy way to tell if it's negative or positive is to see which direction the end of the function on the right side heads in; for the first graph we can see that at x > 1 the gradient is negative, and so the leading coefficient is negative, whilst for the second graph at x > 1 the gradient is positive and so the leading coefficient is positive.
For even functions it would be the same, so for the third graph we can see that the graph has a positive gradient to the right and so the leading coefficient is positive and then for the fourth graph we can see that the graph heads downwards to the right and so the leading coefficient is negative.
So the answers would be:
First graph: The degree of function is odd and the leading coefficient is negative
Second graph: The degree of the function is odd and the leading coefficient is positive
Third graph: The degree of the function is even and the leading coefficient is positive
Fourth graph: The degree of the function is even and the leading coefficient is negative
It is however worth remembering the basic graph of each function that you learn so that these things will become easily identifiable ;)
Answer:
900 grams.
Step-by-step explanation:
1 kg = 1000 grams.
0.9 kg = 1000 * 0.9
= 900 grams.
