<h3>What is Pythagoras theorem? </h3>According to the Pythagoras theorem, the square of the hypotenuse is the sum of the square of the opposite sides.
The Pythagoras theorem: a² + b² = c²
Where:
- a = length
- b = base = 7 miles
- c = hypotenuse = 25 miles
25² - 7²
625 - 49 = 576
√576 = 24 miles

Step-by-step explanation:
From the question we are told that:
Price of 20TVs per week
Marginal price-demand function
Generally the The Marginal price function is mathematically given by
Therefore the equation when the demand is 20 TVs per week at $150 per TV
Giving
Therefore the Price when the demand is 100 TVs per week
First, we separate all instances of t by subtracting J from both sides:
F = J + Jrt
F - J = Jrt
Then, we separate the t by dividing both sides by Jr:
Therefore, t is equal to (F - J) ÷ Jr
F = J + Jrt
F - J = Jrt
Then, we separate the t by dividing both sides by Jr:
Therefore, t is equal to (F - J) ÷ Jr
