When the vertex is at the origin and the directrix is at y = -2.5, the the parabola must be facing upwards and have a general formula of y = 4a x^2. In this case, a is equal to 2.5 that is, y = 4*2.5 x^2 equal to y = 10 x^2
Answer:
The answer is 43 meters below the water.
Step-by-step explanation:
Ana is 35 meters below the water's surface, so if Jesse is 8 meters below her, you would add 8 to 35 and end up with 43 meters below the surface of the water.
