Answer:
At one point, Mellisa is 29 meters below the surface of the water.
A.
As she swims around for the fish, she swims for 12 mins and rises upward by 15 meters.
So, her final depth at the end of the 12 minutes = meters
B.
Mellisa is at a depth of 40 meters. Every minute, she rises 2 meters.
So, in 8 minutes she will rise meters
Her depth will be = meters

Answer:
Step-by-step explanation:
Vertex form is accomplished by completing the square on the quadratic. Do this by first setting the parabola equal to 0 then moving the constant over to the other side:
Now take half the linear term, square it, and add it to both sides. Our linear term is 6. Half of 6 is 3, and 3 squared is 9:
The reason we do this is to create a perfect square binomial on the left:
(obviously the 0 results from the addition of 9 and -9). Move the 0 back over to the other side and set the quadratic back equal to y:
This gives you a vertex of (-3, 0), which is a minimum value, since the parabola opens upwards.
