A certain company's main source of income is a mobile app.
The company's annual profit (in millions of dollars) as a function of the app's price (in dollars) is modeled by
P(x)=-2(x-3)(x-11)P(x)=−2(x−3)(x−11 )P, left parenthesis, x, right parenthesis, equals, minus, 2, left parenthesis, x, minus, 3, right parenthesis, left parenthesis, x, minus, 11, right parenthesis
Which app prices will result in \$0$0dollar sign, 0 annual profit?

To find the extreme values of a function f(x.y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x,y)=xy

Atemperature of 1.64◦f corresponds to answer in units of ◦c.

If the endpoints of the diameter of a circle are (8, 6) and (2,0), what is the standard form equation of the circle? a) (x + 5)2 + (y + 3)2 = 18 (x + 5)2 + (y + 3)2 = 3.72 (x - 5)2 + (y - 3)2 = 18 d) (x - 5)2 + (y - 3)2 = 32
