Answer: 38
Step-by-step explanation: 90 is the right angle for a right angle triangle. Therefore you subtract 90-52.
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!
You apparently began copying in the middle of the problem,
because ALL dimensions are missing from your question.
The answer is C. hope this helps!
