If the instructions for a problem ask you to use the smallest possible domain to completely graph two periods of y=5 + 3cos 2(x-

pi/3) what should you use for the x min and x max

We need two periods so we need to cos go from 0 to 2π

x - pi/3 = 0

x = pi/3

x - pi/3 = 2pi

x = 2pi + pi/3

x = 7pi/3

xmin = pi/3

xmax = 7pi/3

Dy/dx = y/x^2
1/y dy = 1/x^2 dx
int(1/y dy) = int(1/x^2 dx)
ln y + c1 = -x + c2
ln y = -x + c ; c= c2-c1
y = e^(-x+c) = e^c e^-x
y = Ce^-x ; C=e^c

A company earns P dollars by selling x items, according to the equation P(x)=-0.002x^2+5.5x-1000. How many items does the compan

san4es73 [151]

So.. check the picture below

that's when the profit gets maximized

$\bf \qquad \textit{vertex of a parabola}\\ \quad \\

\begin{array}{lccclll}
P(x)=&-0.002x^2&+5.5x&-1000\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}\qquad 
\left(-\cfrac{{{ b}}}{2{{ a}}}\quad ,\quad {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\right)$

how many items does the company need to sell? they need to sell $\bf -\cfrac{{{ b}}}{2{{ a}}}$
