A source of laser light sends rays AB and AC toward two opposite walls of a hall. The light rays strike the walls at points B an
d C, as shown below:
A source of laser light is at point A on the ground between two parallel walls. The walls are perpendicular to the ground. AB is a ray of light which strikes the wall on the left at point B. The length of AB is 60m.AC is a ray of light which strikes the wall on the right at point C which is 40m above the ground. The ray AB makes an angle of 60 degrees with the ground. The ray AC makes an angle of 45 degrees with the ground.
What is the distance between the walls?
the options are
80
140

Answer:
$68
Step-by-step explanation:
We have been given the demand equation for Turbos as , where q is the number of buggies the company can sell in a month if the price is $p per buggy.
Let us find revenue function by multiplying price of p units by demand function as:
Revenue function:
Since revenue function is a downward opening parabola, so its maximum point will be vertex.
Let us find x-coordinate of vertex using formula .
The maximum revenue would be the y-coordinate of vertex.
Let us substitute in revenue formula.
Therefore, the company should sell each buggy for $68 to get the maximum revenue of $18,496.
