Answer: linear function with a negative rate of change
Step-by-step explanation:
A linear function is of the form where x is a independent variable and y is a dependent variable . Here the dependent variable increase ( or decrease)c with a constant rate of increase (or decrease).
An exponential functionis a mathematical function of the form where x is a independent variable, and A is a constant called the initial value of the function. Here the dependent variable increase ( or decrease)c with a constant ratio or percentage.
Given: $1000 is taken out of a bank vault each day and nothing is added back.
So the money in the bank vault decreasing by a constant rate of $1000.
Thus, this shows linear function with a negative rate of change models the situation.

It follows that if the dice are thrown 36 times, you would expect each combination to come up once.
We therefore simply need to know how many combinations add up to less than 5. (I've interpreted this as not including a total of 5 itself).
These combinations are: 1 and 1, 2 and 1, 1 and 2, 2 and 2, 3 and 1, and 1 and 3 ---> six combinations out of 36.
So you'd expect a sum less than 5 six times.

The expression representing the sentence is -
.
We have a sentence - "Ten minus One-third of a number is 4".
We have to determine the expression that represents the sentence.
Express the statement - "The difference of x and y is equal to an irrational number" in the form of expression.
The expression representing the above statement is -
x - y = π
According to the question, we have -
Ten minus One-third of a number is 4
Assume the number to be x.
We can write it as a expression -
Hence, the expression representing the sentence is
