No, that's not true. The input variable of a sequence is called the index, which is a counter, such as 1, 2, 3, 4, ... Note that all of these counters are positive integers. Normallly I use index i = 1 to denote the first term of a sequence, i = 2 the second term, and so on.
Decimals and irrational numbers are completely unsuitable for serving as such counters.

Answer:
Step-by-step explanation:
Let the amount of flour left be .
Initial amount of flour = 18 cups
Cups used for 1 batch of muffins = 3
∴ Cups used for batches =
Amount left in the container is given as:
Therefore, the equation to show how much flour is left in the container after x batches of muffins is .
The graph of it is shown below.
Find the x and y intercepts and then join the line.
At x intercept,
So, x intercept is
At y intercept, ,
So, y intercept is
Join these two points to plot the graph.
It is given in the question that initial amount of C 14 is 10 gms .
So after first half life,initial amount of C 14 becomes half , that is 5 grams .
After second half life, the amount left is the half of the amount that we got after first life, that is half of 5 gm which is 2.5 grams .
So after two half lives, the 10gm C 14 becomes 2.5 gm C 14 .
4 quarts = 1 gallon, so 14 gal is equal to 56 quarts. So 56 quarts per second, times 60 seconds equals 3360 quarts per minute. Hope this helped!
