Answer:
The correct answer is 8 %.
Step-by-step explanation:
We have a product that costs 3.25. Including the tax, the total amount of this product will be 3.51.
Now we must find out what was the percentage applied to the ice cream.
We do it as follows:
We know that the total tax was 0.26.
To find out the percentage we will use the formula
Where P represents the percentage we want to obtain, B is the value of the tax, and A is the value of the product without the tax.
We multiply that result by 100.
P =
In this way we can show that 8% is the percentage applied.
Answer:
The average rate of change is
Step-by-step explanation:
The average rate of change from x=a to x=b of f(x) is given by;
We want to find the average rate of change of the function represented in the table from x=-2 to x=2.
From the table f(-2)=25 and f(2)=9
The average rate of change from x=-2 to x=2 is
Answer:
Diverge
Step-by-step explanation:
(a)
1st year:
2nd year:
3rd year:
4th year:
5th year:
(b) The sequence is divergent, because if we take the derivative of the function with respect to n year:
This is a positive, meaning the slope of the function is positive. If we take the second derivative using product rule
This is also positive when n > 0. Therefore, the slope is positive and increasing. This means the sequence diverges.
