Answer:
i think sample 1 and 2
Step-by-step explanation:
I think it is but i am not sure it could also be none because depending on the way u think of it it could be a little variability
Let x denote the number of times at which price is increased by $5 for each magazine.
{Write an expression for the total revenue of company}
Let y denote the total revenue of the company,
y = (2000 - 200x) × ($40 + $5x)
{200x is the number of subscriptions being lost due to the price increases}
{$5x is the amount of increase in price of each magazine}
y = 2000($40) + 2000($5x) - 200x($40) - 200x($5x)
y = $80,000 + $10,000x - $8000x - $1000x^2
y = $80,000 + $18'000x - $1000x^2
{Since the coefficient of x^2 is (-1000), this graph is a sad face curve. This means the only stationary point on the curve is a maximum point}
{Differentiate y in terms of x}
dy/dx = $18,000 - $2000x
{dy/dx = 0 at stationary point, or when gradient = 0}
dy/dx = 0
$18,000 - $2000x = 0
$2000x = $18,000
x = 9 {dollar signs cancel out when they are divided}
Subscription price to attain maximum revenue should be: $40 + (9 × $5) = $95
Hope this helps!
It is 98 ( hopefully I am right)
Answer: y-32+4y
Step-by-step explanation:
y-32: the difference of y and 32. +4y : <u>plus the product of y and 4</u>
Answer:
b. line j or MT
Step-by-step explanation:
as the plane contains the points Q, N, P, R, T also the lines connecting only these points are in the plane, and are not intersecting the plane.
only M is outside of the plane, and so (only) the connecting line MT intersects the plane (at point T).
by the way, the question means the line RQ and not RO, as there is no point O in the graphic.
