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.

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.

the correct answer is actually B, C and F

Step-by-step explanation:

i just took the test! :)

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
