Question
**Body Mass Index (BMI) Calculation**

The body mass index (BMI) for an adult is determined using the formula:

\[ B = \frac{w}{h^2} \]

Where:
- \( B \) is the BMI,
- \( w \) is the weight (actually mass) in kilograms,
- \( h \) is the height in meters.

### Questions

1. **What is the BMI for a person who is 1.8 meters tall and weighs 80 kilograms?**

2. **Calculate the partial derivatives \(\frac{\partial B}{\partial w}\) and \(\frac{\partial B}{\partial h}\).**

### Explanation

To calculate the BMI:
- For a person with a height of 1.8 meters and a weight of 80 kilograms, substitute these values into the BMI formula.

To calculate the partial derivatives:
- Determine how the BMI changes with respect to weight (\(w\)) and height (\(h\)).

Expert Solution
Step 1

Given that,

The body mass index for an adult is given by the function B=wh2, where w is the weight in kilograms and h is the height in meters.

1.

Given that,

Person 1.8 meters tall, so heigh is 1.8 meters.

height of a person is 1.8 meters and weight is 80 kilograms.

By using the formula of BMI,

B=wh2=801.8=44.4444

Thus, the BMI for a person is 44.4444 kg /m2
