The tip of a toy arrowhead shaped as an isosceles right triangle is sketched on a graph. the endpoints of one leg are (0,0) and
1 answer:
We need to find the length of the longest side of an arrowhead.
Length of the longest side of the tip is .
The length of one of the legs of the isosceles right triangle is 10 units.
Since, it is a isosceles right triangle, two sides will have equal lengths.
So, the other side of the triangle will also be 10 units and the angle between these two sides will be .
So, the Pythagoras theorem can be used to find the third side which will be the longest.
The length of the longest side of the tip is .

Answer:
The maximum revenue is $1,20,125 that occurs when the unit price is $155.
Step-by-step explanation:
The revenue function is given as:
where p is unit price in dollars.
First, we differentiate R(p) with respect to p, to get,
Equating the first derivative to zero, we get,
Again differentiation R(p), with respect to p, we get,
At p = 155
Thus by double derivative test, maxima occurs at p = 155 for R(p).
Thus, maximum revenue occurs when p = $155.
Maximum revenue
Thus, maximum revenue is $120125 that occurs when the unit price is $155.
