F(6)= 2*(6^2) +5 *sqrt(6-2) = 2*36+ 5*sqrt(4) = 72 +5*2 =72+10 =82
You’re interested in 18th to find the area you take two and one 4th×4 and one half that equals 10/18
Step-by-step explanation:
As you found in parts a and b, p = 840 − 2x, and R(x) = -2x² + 840x.
For part c, profit = revenue − cost.
P(x) = R(x) − C(x)
P(x) = -2x² + 840x − (2x² + 15x + 1500)
P(x) = -2x² + 840x − 2x² − 15x − 1500
P(x) = -4x² + 825x − 1500
The maximum profit is at the vertex of the parabola.
x = -b / (2a)
x = -825 / (2 × -4)
x = 103.125
Or, we can use calculus:
P'(x) = -8x + 825
0 = -8x + 825
x = 103.125
Rounding, the manufacturer should produce 103 refrigerators each week.
