The height of the projectile above the ground at any given time can be modeled using the quadratic equation h = -5t² + 20t, where h is the height and t is the time in seconds. To find the maximum height of the projectile, we can use the quadratic formula to solve the equation.
Example 2: A company is planning to launch a new product, and the demand for the product can be modeled using the quadratic equation d = -2x² + 10x, where d is the demand and x is the price of the product. To find the optimal price for the product, we can use the quadratic formula to solve the equation.
These are just a few examples of how the quadratic formula is used in real-world applications.
