<span>A it is the answer maybe according for the question</span>
This is what she/he is saying:
A stone is thrown into a pool of calm water which creates concentric waves that increase the radius over time. When the external wave reaches a radius of 3 meters, it increases at a speed of 5 cm / s, at what speed does this area of the circle increase by said wave?
Answer:
- f.x=2x-7
- f.-3=(2×-3)-7
- f.-3=-6-7
- f -3=-13
Step-by-step explanation:
hope it is correct
The formula is in a quadratic formula shape: 
The function is negative since the value 'a' the coefficient of x^2 is negative meaning that the quadratic function is facing downards. If you don't get this explanation, take a look at the diagram I uploaded.
That means the highest point of the graph is its vertex.
But we must find where the vertex is at or the 't' value.
't' value at which vertex is = 
Now plug this 't' value into h(t) to find the maximum height, and we will get 36 feet.
Hope that helps!
