Since the value of the coin collection rises proportionally every year, this functions exponentially.
What are exponential functions?The exponential function in mathematics is represented by the symbols f(x)=exp or ex. The word, unless otherwise stated, normally refers to the positive-valued function of a real variable, though it can be extended to the complex numbers or adapted to other mathematical objects like matrices or Lie algebras. f(x) = bx, where b > 0 and b 1, is the formula for an exponential function. B is referred to as the base and x is referred to as the exponent, just like in any exponential expression. Bacterial proliferation is an illustration of an exponential function. Some bacteria grow by two folds per hour. The exponent is the independent variable, or x-value, in an exponential function, while the base is a fixed value. An exponential function would be, for instance, y = 2x. Here is what that appears to be.

There are 167 students taking a foreign language at North HighSchool. Based on the graphic above, how many students are takingSpanish?
Answers
59 (1st option)
Explanation:Given:
Total students taking the foreign language = 167
To find:
The number of students taking Spanish
To determine the number of students for Spanish, we will do an estimation:
The Spanish region is represented by the red region
The blue and red region is approximately half of the circle. This means half of the total students
Half of the students = 1/2(167) = about 83 students
The blue region in the half of the circle is about 1/3. The red represents the remaining part (2/3)
The Spanish region = 2/3 × 83
The Spanish region = 55.3

Suppose Julia spends $932 on her credit card. Calculate the amount of interest she would owe in one month if she does NOT pay off her balance in full by the due date. Julia's APR is 16.99%. Estimate the interest charges using the monthly periodic rate
Answers
Answer:
The amount of interest she would owe in one month if she does not pay off her balance in full by the due date is $13.2
Explanation:
Given that Julia's APR is 16.99%
Suppose she spends $932 on her credit card, the amount of interest she would owe in a year is 16.99% of $932, this amounts to
0.1699 * 932
= $158.3468
To know the interest in a month, we divide the last result by 12
158.3468/12
= $13.196
This is approximately $13.2

Answers
Explanation:
A relation is a function if every value of x is related to just one value of y.
So, number 6 is not a function because -4 is related to 9 and -4 is also related to 0.
Number 7 is a function because every value of x (first coordinate) is related to one value of y (second coordinate).
In the same way, we can say that number 8 is also a function and number 9 is not a function because number 7 is related to 0, -5, -8, 4, and 3.
Finally, for the graph of numbers 10, 11, and 12 we need to identify the coordinates of every point.
So, number 10 is equivalent to:
{(-7, -1), (-2, -7), (0, 2), (4, 2), (6,6)}
It means that number 10 is a function
For number 11, we get:
{(-5, -4), (-3, 5), (2, -1), (2
