Which of the following are situations that can be modeled with a quadratic function? select all that apply. a tree decays 10% every six weeks. the height of a diver after jumping from a high dive into the water. the height of a ball rolled down a hill. a gym charges $15 per fitness class. an antibiotic eliminates 50% of bacteria every 24 hours. the height of a rocket after it is launched.

the correct answer is actually B, C and F

Step-by-step explanation:

i just took the test! :)

Option 2 and 5 are correct.

Step-by-step explanation:

We need to tell which one of them is quadratic function.

Option 1 is exponential decay so, it is not quadratic.

Option 2 is quadratic because the diver will take the parabolic shape when jumps.

Option 3 is not quadratic.Option 4 is not quadratic it is linear.

Option 4 is again exponential not quadratic.

Option 5 is quadratic because it takes the parabolic shape again.

  x = 2

Step-by-step explanation:

There are no algebraic methods for solving an equation like this.

The proof of Fermat's Last Theorem demonstrates that no integer x-value can possibly exist that is greater than 2. Trial and error (or your familiarity with Pythagorean triples) tells you that x=2 is a solution for this equation. Equations like this can be solved graphically, as in the attached.
