Answer:The first table would be a proportional relationship.
Step-by-step explanation:
It's the only table with a constant, which is required in a proportional relationship. The constant would be 1300 which you can find by divided the two numbers in each row.
The atomic mass of an atom tells us about how much the atom weighs.
Option A
<u>Step-by-step explanation:</u>
The atomic mass of an atom tells us about the weight of the atoms. An atom can be represented using the mass number denoted as A and atomic number denoted by Z. As atomic number is the number of protons present in the atom, mass number denotes the sum of protons and neutrons present in the atom.
So, the mass number will be approximately equal to the atomic mass. It can be also stated that atomic mass represents the weight of the atoms. The elements are arranged in the increasing order of their atomic mass in the periodic table.
Answer:
brainiest?
Step-by-step explanation:
Find the powers 
$a^{2}=5+2 \sqrt{6}$
$a^{3}=11 \sqrt{2}+9 \sqrt{3}$
The cubic term gives us a clue, we can use a linear combination to eliminate the root 3 term $a^{3}-9 a=2 \sqrt{2}$ Square $\left(a^{3}-9 a\right)^{2}=8$ which gives one solution. Expand we have $a^{6}-18 a^{4}-81 a^{2}=8$ Hence the polynomial $x^{6}-18 x^{4}-81 x^{2}-8$ will have a as a solution.
Note this is not the simplest solution as $x^{6}-18 x^{4}-81 x^{2}-8=\left(x^{2}-8\right)\left(x^{4}-10 x^{2}+1\right)$
so fits with the other answers.
