Answer: The maximum revenue is $1,000,000.
The function that is given is a quadratic equation and the graph would be an upside down parabola.
Therefore, the maximum revenue would be at the vertex of the parabola.
To find the vertex, we can use the expression -b/2a to find the x-value.
It would be -4000/2(-4) = 500
Now, input 500 for p and you will get a revenue of 1,000,000.
Answer:
a1=2 and r=-1
Step-by-step explanation:
Given
geometric series= 2-2+2-2+2
geometric sequence has a constant ratior r and is given by
an=a1r(r)^(n-1)
where
an=nth term
r=common ratio
n=number of term
a1=first term
In given series:
r= a(n+1)/an
= a(2)/a1
= -2/2
=-1
so a1=2 and r=-1 !
