Answer:
(B) an update from the bank when an account balance is less than $50
Step-by-step explanation:
overdraft occurs when money is withdrawn in excess of what is on the current account. In this situation the account is said to be "overdrawn". This applies to debit cards and how much you have on your balance :)
I assume you want the leading coefficient because there is only 1.
The leading coefficient is always in front of the term with the greatest exponent.
Leading coefficient = -1.
The degree of this function is 9. It is a ninth degree polynomial function. Why 9? It is a 9th degree polynomial because 9 is the greatest power.
Answer: The total number of logs in the pile is 6.
Step-by-step explanation: Given that a stack of logs has 32 logs on the bottom layer. Each subsequent layer has 6 fewer logs than the previous layer and the top layer has two logs.
We are to find the total number of logs in the pile.
Let n represents the total number of logs in the pile.
Since each subsequent layer has 6 fewer logs then the previous layer, so the number of logs in each layer will become an ARITHMETIC sequence with
first term, a = 32 and common difference, d = -6.
We know that
the n-th term of an arithmetic sequence with first term a and common difference d is

Since there are n logs in the pile, so we get

Thus, the total number of logs in the pile is 6.
An exponential parent function is the option C. f(x)=
, from the given options.
What do you mean by exponential parent function?
The formula for their parent function is y =
, where b is any non zero constant. Below is a graph of the parent function, y =
, which demonstrates that it will never equal 0. And at y = 1 when x = 0, y crosses the y-axis.
According to options in the given question,
We have the option below in the given question:
A. f(x) = 2^x – 3 
B. f(x) = 2^x + 2 
C. f(x) = 2^x 
D. f(x) = 2^x + 1/3
We know from the above definition that the option C. is the right answer to the given question.
Therefore, the exponential parent function is f(x)=
.
