The value of the expression will be 8.166.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The mathematical expression is,
⇒ 13.41 x (5.4 divided by 9)
Now,
Solve the expression as;
⇒ 13.41 x (5.4 divided by 9)
⇒ 13.41 x (5.4 ÷ 9)
⇒ 13.41 x 0.6
⇒ 8.166
Thus, The value of the expression will be 8.166.

Answer:
Cost of a single light bulb is $3.34
Step-by-step explanation:
Value of sales tax = 6% ×$71.02
= $4.2612
Total cost of bulb before tax = Total cost of bulb - Value of sales tax
= $71.02 - $4.2612
= $66.7588
Value of a single light bulb = Total cost of bulb before tax ÷ Total number of light bulbs
= $66.7588 ÷ $20
= $3.33794
= $3.34 Approximately.

Using the vertex of a quadratic equation, it is found that the company should charge each customer $15 per day to maximize revenue.
<h3>What is the vertex of a quadratic equation?</h3>
A quadratic equation is modeled by:
The vertex is given by:
In which:
Considering the coefficient a, we have that:
- If a < 0, the vertex is a maximum point.
- If a > 0, the vertex is a minimum point.
In this problem, the number of bikes rented per day is given by:
n(p) = 300 - 10p.
Hence, the revenue function is given by:
R(n) = p x n(p)
R(n) = 300p - 10p².
Which is a quadratic function with coefficients a = -10, b = 300. Hence, the price in dollars that will maximize the revenue is given by:

A U B is the set of elements which are in A, in B, or in both A.
Since,
A = {2, 3, 6}
B = {2, 4, 5, 7}
To find A U B, we have to write all numbers that are in A and/or in B. The number that are in both sets must not be written again.
A U B = {2, 3, 6, 4, 5, 7}
Writing then in acending order:
A U B = {2, 3, 4, 5, 6, 7}
Answer: A U B = {2, 3, 4, 5, 6, 7}.
