The length of segment XY can be found by solving for a in
The measure of the central angle is
.
Step-by-step explanation:
If the regular octagon has a perimeter of 122.4cm, then each side is
The measure of each central angle is
The angle between the apothem and the radius is
The segment XY=a is the height of the right isosceles triangle.
We can use the Pythagoras Theorem with right triangle XYZ to get:
Therefore, the correct options are:

Answer:
5 cm
Step-by-step explanation:
Given the function:
As we know the above function is a quadratic equation (vertical parabola) open downward and the vertex is the maximum number of mosquitoes.
The vertex form of a quadratic function is:
where (h,k) is the vertex
Our given function have the vertex form as well, so the
(h,k) = (5,25)
At the height of 5 cm the rainfall will produce the maximum number of mosquitoes
