When Akbar’s son was four years old, Akbar put $250 into an account that guaranteed a 10% annual return. The equation f(x=250(1.
10) represents the amount of money in the account when the child will be x years old. Which graph models the scenario?
2 answers:
A screenshot of the graph is attached.
The graph starts at $250, as that is the amount invested, and increases exponentially from that point.
The graph starts at $250, as that is the amount invested, and increases exponentially from that point.
Answer:
The graph is attached below.
Step-by-step explanation:
The general form of the exponential function is
where,
a = initial amount
r = rate of change
This is used in case of compound interest. Putting the values,
Here,
a = 250 as at the beginning Akbar added $250 into the account
r = 10% as the amount is increased by 10% from the previous amount
Plotting the graph.
As the initial amount is 250, i.e the y intercept of the graph will be 250.
As neither years (x) not amount of money (y) be negative, so the graph will be in the 1st quadrant.

Answer:
472 3/4
Step-by-step explanation:
Consider the meaning of "one, and one more". That does not mean zero (1-1). Rather, it means two (1+1).
__
Then 3/4 and 472 more is ...
Eric has 472 3/4 buckets filled with sand.
_____
The problem statement here seems to be focused on the filled buckets, rather than the sand stockpile that Eric is working from. The amount in that stockpile is being reduced by the amount that is being used to fill buckets. In short, whether you add or subtract depends on what you're trying to figure.
