The question is an illustration of combination and there are 729 potential pass codes available
<h3>How to determine the number of potential pass codes?</h3>
The given parameters are
Symbols available = 9
Length of pass code = 3
From the question, we understand that a symbol may be entered any number of times.
This means that each of the 9 available symbols can be used three times
So, the number of potential pass codes is
Passcodes = 9 * 9 * 9
Evaluate the product
Passcodes = 729
Hence, there are 729 potential pass codes available

Answer:
Inorganic compounds — simple molecules that usually consist of one or two different elements ; for example:
Water (H2O)
Carbon dioxide (CO2)
Bimolecular oxygen (O2)
Sodium chloride (NaCl)
Step-by-step explanation:
The break even point is that where the total cost is equal to the total revenue. To determine the number of hours in which Quick Fix Inc. will have a breakeven, we have to equate the two equations and solve for the value of x,
400 + 220 x = 20x² + 160
The values of x from the equation are 12 and -1. Since, we do not have a negative for the number of hours, our answer is 12 hours.
Answer:
Step-by-step explanation:
<u>Let's complete the square first:</u>
- p⁴ - 2p²x² + x⁴ + x =
- p⁴ + 2p²x² + x⁴ - 4p²x² + x =
- (p² + x²)² - (4p²x² - x)
<u>In order the expression above to be a perfect square, we need:</u>
<u>Solve it for x:</u>
- 4p²x² = x
- 4p²x = 1
- x = 1/(4p²)
Correct choice is d
