The student concluded that -
The bubbles indicated a chemical change was occurring.
Please find the attached diagram for a better understanding of the solution provided here.
In the attached diagram, OP is the height of the tree.
Rest of the diagram should be sufficiently self explanatory.
In ,
.........................Equation #1
Again, in ,
.........................Equation #2
Thus, equating the equations Equation #1 and Equation #2, we have:
Evaluating we get:
Thus the height of the tree is approximately 49.26 feet
Vertex = (1,-4)
Focus = (1, -1)
Directix =
y= -7
Hope this helped
