Note that

, where

is the area,

is the length, and

is the width. Substituting our values in, we have:

Multiplying by

gives:

So the width is

miles.
All functions have an inverse expression.
- The cost function is:
. - The inverse function is:

From the question, we have the following observations:
- Base fare = 50000 pesos for first 100
- Additional guest = 100 pesos
So, the cost function would be:

Where: x represents the number of guests, and C(x) represents the cost function
Expand

Evaluate like terms

To calculate the inverse function, we have:

Replace C(x) with y

Swap x and y

Subtract 40000 from both sides

Divide both sides by 100

Rewrite as:

Split


Hence, the inverse function is:

Answer:

Step-by-step explanation:
I am assuming that the division problem looks like this:
-2| 1 2 -3 1
Going off that assumption, we will work this problem. The first thing you always do in the execution of synthetic division is to bring down the first number. Then multiply that number by the one "outside", which is -2, then put that number up under the next number in the line:
-2| 1 2 -3 1
-2
1
Now add the 2 and -2 and bring that down as a 0 and multiply the -2 times the 0:
-2| 1 2 -3 1
-2 0
1 0
Now add -3 and 0 to get -3 and multiply that -3 times the -2 and put the product up under the next numbe in line;
-2| 1 2 -3 1
-2 0 6
1 0 -3
Now add the 1 and the 6 to get the remainder:
