Answer:
Step-by-step explanation:
We are asked to write 340,000,000 in scientific notation.
To write a number is scientific notation, we need to numbers whose product is equal to the given number.
The first number is between 0 and 10 and second number is a power of 10.
The first factor of our number between 0 and 10 would be 3.4. Now we need to raise 10 to such a power whose product with 3.4 gives us 340,000,000.
We will raise 10 to the 8 power as equals 340,000,000 and there are 8 digits after decimal, therefore, our required number is
in scientific notation.

Answer:
Option (4)
Step-by-step explanation:
Proportional relationship means,
y ∝ x
y = kx
Here, k = proportionality constant
Therefore, if the graph of a line passes through the origin (0, 0) table will represent the proportional relationship.
From table 1,
For a point (1, 2)
For another point (3, 2)
In both the cases 'k' is not same of constant.
Therefore, table (1) is not proportional.
For table (2),
Line passes through (2, 0).
That means there is a x-intercept → (2, 0)
Therefore, table doesn't represent a proportional relationship.
For table (3),
Line passes through a point (0, 1)
It means given line has a y-intercept → y = 1
Therefore, table doesn't represent a proportional relationship.
For table (4),
Line of this table passes through two points (1, 3) and (2, 6)
Therefore, proportionality constant for the given table is 3.
Now we can graph table (4).
