Answer:
A. 7
Step-by-step explanation:
Since the triangle sides are not defined, therefore let the base side have the 12 unit and one of the slant side be 7 unit.
Therefore height of the triangle, h can gotten from the Pythagoras theorem as thus:
7² = (12/2)² + h²
49 = 36 + h²
h² = 49 - 36 = 13
h = √13
knowing the height of the triangle, we can apply same rule to the other unknown slant side, x as thus:
x² = (12/2)² + h²
x² = 36 + 13 = 49
x = √49
x = 7
The demand equation illustrates the price of an item and how it relates to the demand of the item.
- The slope of the demand function is -1/2
- The equation of the demand function is:
- The price that maximizes her revenue is: Ghc 85
From the question, we have:
The number of plates (x) decreases by 10, while the price (y) increases by 5. The table of value is:
The slope (m) is calculated using:
So, we have:
The equation of the demand is as follows:
The initial number of plates (300) decreases by 10 is represented as: (300 - 10x).
Similarly, the initial price (20) increases by 5 is represented as: (20 + 5x).
So, the demand equation is:
Open the brackets to calculate the maximum revenue
Equate to 0
Differentiate with respect to x
Collect like terms
Divide by 100
So, the price at maximum revenue is:
In conclusion:
- The slope of the demand function is -1/2
- The equation of the demand function is:
- The price that maximizes her revenue is: Ghc 85
