Answer:
there is no price for which weekly revenue would be 1800
Step-by-step explanation:
If there is a solution to the equation ...
r = 1800 = -4p² +40p +1287
then there is a solution to ...
4p² -40p +513 = 0
Comparing this to the standard form quadratic equation
we can match coefficients to see that ...
The discriminant of a quadratic is ...
When we fill in the numbers and evaluate, we find the discriminant is negative. This tells us that solutions to the equation are complex—there are no real solutions, meaning there is no price that will give $1800 weekly revenue.
_____
A graph shows the highest weekly revenue obtainable at any price is $1387, so there is no price that will give revenue of $1800.
Answer:
= 270 ⇒ Last answer
Step-by-step explanation:
* If f(x) = 7 + 4x
* If g(x) =
* We want to find
- Lets find at first
∵ f(x) = 7 + 4x
∵ g(x) =
∴
- Lets divide the numerator by the denominator
∵ The numerator is 7 + 4x
∵ The denominator is
∴ (7 + 4x) ÷
- Lets reverse the division sign to multiplication sign and reciprocal
the fraction after the division sign
∴ (7 + 4x) ×
∴ = 2x(7 + 4x)
∴ = 14x + 8x²
- Now substitute x by 5
∴ = 14(5) + 8(5)² = 70 + 200 = 270
∴ = 270
