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:
50 students
Step-by-step explanation:
Hello!
To solve this question, we would first need to look at the data. In this data, there are people who chose their favorite sport, and the number of people who chose that response. In order to solve the problem, we would have to find the ratio of how many people choose baseball over the other sports.
By this, we can add the number of students together. 30+10+5+15=60. Out of those 60 students, only 5 people chose baseball.
Since the ratio of the people who chose baseball is 5/60 (meaning that it is a 5/60 % chance someone would pick this sport), we would need to find the amount of people assumed to pick baseball in 600 student survey.
We can make a relationship with these two numbers.
, since the ratio of the students who chose baseball remain the same.
You can see that the ratio on the denominators just add a zero on the bottom, so the top should add 0 as well, to get 50 for x, what we needed.
You can also solve that relationship by cross multiplication.
5(600)=x(60
3000=60x
50=x
Regardless, the answer is 50 students who would choose baseball in a 600 persons survey.
