Answer:
The correct option is;
C. The rate at which the account is increasing
Step-by-step explanation:
The given parameters are;
The rate at which the compound interest on the savings account is compounded = quarterly
The expression given by her banker to find the amount in the account after t years = 4,200(1.05)^(4t)
Therefore, the 1.05 = The rate at which the account is increasing
The interval notation that defines this set is: (-∞, -5]
And the graph can be seen below.

How to graph the inequality?</h3>
Here we want to graph the inequality:
x ≤ -5
This refers to all the values of x equal or smaller than -5.
To graph this, we need to graph a closed circle at -5, and we need to draw an arrow that points to the left (values smaller than -5). The graph is the one that you can see below.
The interval notation that defines this set is: (-∞, -5]
The first end is open, and the second is closed (because of the symbol ≤).

Using function concepts, we have that:
- The independent quantity is the time.
- The dependent quantity is the volume.
- Graph H fits this problem.
<h3>What is the relation between a function and the dependent and independent variables?</h3>
A function has the following format: y = f(x).
In which each value of <u>y is a function of one value of x</u>, and thus, x is the independent variable and y is the dependent variable.
That is, the input of the function is the independent variable and the output is the dependent variable.
For this problem, the <u>volume is a function of time</u>, hence Volume = f(Time) and:
- The independent quantity is the time.
- The dependent quantity is the volume.
The <u>decay rate is constant</u>, meaning that we have a <u>decreasing linear function</u>, and graph H fits this problem.

Answer:
34 hours or more
Step-by-step explanation:
If h is the number of hours Jack works, then his earnings will total 15h. He wants that to be at least 500. The appropriate inequality is ...
15h ≥ 500
h ≥ 33 1/3 . . . . . divide by 15
Jack needs to work 34 hours or more to earn at least $500.
