Answer:
4m²-24mn+9n²
Step-by-step explanation:
- Separate equation out so it is (4m-3n)×(4m-3n)
- FOIL (First, Outside, Inside, Last) your polynomial
- Should have equation 4m²-12mn-12mn+9m²
- Combine like terms
- Result: 4m²-24mn+9m²
To determine how many acres would minimize cost, we need to differentiate the expression given and set it to zero and obtain the value of x. We do as follows:
C(x) = 0.2x^2 - 12x +240
C'(x) = 0.4x - 12
0 = 0.4x - 12
x = 30 acres <---------amount of flowers needed to minimize cost
Answer:
Increasing by $66 per day
Step-by-step explanation:
If sales are dropping at a rate of 2 per day, the sales function is:
If price is increasing by $1 per day, the daily price function is:
Revenue is given by daily sales multiplied by daily price:
The derivate of the revenue function gives us the daily rate of change in revenue:
Currently (t=0) her daily revenue is changing by:
Her revenue is increasing by $66 per day.
Answer:
It is a solution to the equation
Step-by-step explanation:
We just need to bring the value 9 to the right hand side of the equation
So we have;
x = 17 -9
x = 8
