Answer:
23.2%
Step-by-step explanation:
First we need to find how many half lives 135 years is:
135 ÷ 64 = 2.109375
Now we divide 100% by 2 to the power of the number of half lives. This is how you calculate the percentage of the original amount left. If you have the original mass, you can substitute that in instead of 100%:
100 ÷
= 23.1747390635
To 1 decimal place it is 23.2%

Answer:
The table will be:
x y=x+1
1 2
2 3
3 4
4 5
5 6
The graph is shown in figure attached.
Step-by-step explanation:
We need to create table and graph the expression: 
Table is made, such that we take value of x and find value of y
You can take any values of x from negative values to positive values. I am taking values of x: 1,2,3,4,5 and find value of y.
So our table will be:
x y=x+1
1 2
2 3
3 4
4 5
5 6
Now, we will plot these value on the graph. x values will be on x-axis and corresponding y-values will be on y-axis.
The graph is shown in figure attached.
Answer:
-3119
Step-by-step explanation:
(-5)^2 - 2 x (-9) + 6
-5^2 - 2 x -9 + 6
-3125 - 2 x -9 + 6
-3125 - -18 + 6
-3125 - -6
-3119
I hope this helps :)
