Answer: 140
Step-by-step explanation:
If no. of apartments are y
35% of y = 49
Y = 4900/35 = 140
The general equation of a hyperbola with a horizontal transverse axis is defined as:
x²/a² - y²/b² = 1
Solving for b², we use the formula: a² + b² = c²
b² = 12² - 9² = 63
Equation of our hyperbola will be:
x²/81 - y²/63 = 1
Answer:

Step-by-step explanation:
We are given: 
So, the integral will be used to calculate the volume.
