We want our exponential function to look like
y = ab^x.
Let a = the initial y-value.
Our initial value is the first number given for f(x). So, a = 3.
Let b = the number that is needed to go from 3 to 6 to 12 to 24 to 48.
We find b by division.
So, b = the next number divided by the previous.
So, b = 6/3 = 2.
We now plug in our values into the general formula above.
y = ab^x
Answer: y = (3)(2)^x
The formula for the volume of a cube is:
v=s³
Where v=volume and s=the length of a side
Since we know that the length of a side of the gift box is 15cm, we can solve for the volume.
v=15³=3375cm³
Answer: V=3375cm³
Answer:
2.28%
Step-by-step explanation:
The z score is used to determine how many standard deviations that the raw score is above or below the mean. If the z score is positive then the raw score is above the mean and if it is negative then it is below the mean. It is given by:

Answer:
(c) or 10 is the answer
Step-by-step explanation:
In order to find slope you have to follow the formula
(y2-y1) / (x2-x1)
That would give you the slope which in this case is 10.
9 years * 5% = 45%
300,000 * 45 = 13,500,000
13,500,000 / 100 = 135,000 people
300,000 + 135,000 = 435,000 people after 9 years
