The best pricing decision that is made is to sell each unit for $3.

<h3>How to calculate the price?</h3>

From the information given, the revenue will be:

= Customer × Charge

= 16 × 10

= 160

Based on the information given, the equation will be:

(10 + x)(16 - 2x) ≥ 130

160 - 20x + 16x - 2x² ≥ 130

-2x² - 4x + 30 ≥ 0

x² + 2x -15 ≤ 0

(x+1)² ≤ 4²

x+1 ≤ 4

x ≤ 3

1) X²+5X-50=0

↠X² + 10X -5X -50 = 0

↠X(X+10)-5(X+10) = 0

↠(X-5)(X+10)=0

↠X = 5, -10

2)B²+6B-16=0

↠B² + 8B - 2B -16 = 0

↠B(B+8) -2(B+8) =0

↠(B-2) (B+8) =0

↠B = 2,-8

3)R²+6R+8=0

↠R²+4R+2R+8=0

↠R(R+4)+2(R+4)=0

↠(R+2)(R+4)=0

↠R=-2,-4

4) P²+5P+6=0

↠P²+3P+2P+6=0

↠P(P+3)+2(P+3)=0

↠(P+2)(P+3)=0

F(x)=e*1/x<br>Calculate f'(x)

Murljashka [212]

Answer:

$\huge\boxed{f'(x)=-\dfrac{e^\frac{1}{x}}{x^2}}$

Step-by-step explanation:

$(e^x)'=e^x\\\\\bigg[f\bigg(g(x)\bigg)\bigg]'=f'\bigg(g(x)\bigg)\cdot g'(x)\\\\\left(\dfrac{1}{x}\right)'=-\dfrac{1}{x^2}\\\\====================$

$f(x)=e^\frac{1}{x}=\left(e^\frac{1}{x}\right)'\cdot\left(\dfrac{1}{x}\right)'=e^\frac{1}{x}\cdot\left(-\dfrac{1}{x^2}\right)=-\dfrac{e^\frac{1}{x}}{x^2}$
