The function I = 19n is a linear function
The reasonable domain of the function is [0,21]
<h3>How to determine the domain?</h3>
The function is given as:
I = 19n
The smallest value of n is 0 i.e. the smallest number of ticket sold is 0
The maximum capacity is 400.
So, we have:
19n = 400
Divide both sides by 19
n = 21.05
Remove the decimals
n = 21
Hence, the reasonable domain of the function is [0,21]

Step-by-step explanation:
<u>Step 1: Define</u>
5(w + 2.2) - 4w = 9.3
<u>Step 2: Solve for </u><em><u>w</u></em>
- Distribute 5: 5w + 11 - 4w = 9.3
- Combine like terms: w + 11 = 9.3
- Isolate <em>w</em>: w = -1.7
<u>Step 3: Check</u>
<em>Plug in w into the original equation to verify it's a solution.</em>
- Substitute in <em>w</em>: 5(-1.7 + 2.2) - 4(-1.7) = 9.3
- (Parenthesis) Add: 5(0.5) - 4(-1.7) = 9.3
- Multiplication: 2.5 + 6.8 = 9.3
- Addition: 9.3 = 9.3
Here we see that 9.3 does indeed equal 9.3.
∴ w = -1.7 is the solution to the equation.
Answer:
Hence, Option 'C' is true.
Step-by-step explanation:
Given the expression
Apply distributive law:
Here:
so the expression becomes
∵
Therefore,
Hence, option 'C' is true.
Answer:
