Katena32 [7]

Answer:

below

Step-by-step explanation:

$x.4 ( x-4) = 36 \\$

$4x(x-4) = 36 \\$

$4x^{2} - 16x = 36$

add -36 to both sides

$4x^{2} - 16x - 36 = 36 -36 \\4x^{2} -16x - 36 = 0$

divide both sides by 2

$\frac{4x^{2} - 16x - 36 }{4} = 0/4$

$x^{2} -4x-9 = 0$

This is a quadratic equation

let's solve it by graphing it

The solution are the x-coordinates of the intersection points

The x-coordinates of the intersection points are approximatively -1.6 and 5.6

Find the average of e^-x over [0,3]

yaroslaw [1]

The average value of a continuous function f(x) over an interval [a, b] is given by the integral,

$\displaystyle \frac1{b-a}\int_a^b f(x)\,\mathrm dx$

Compute the integral for f(x) = e ⁻ˣ over [0, 3] :

$\displaystyle \frac1{3-0}\int_0^3e^{-x}\,\mathrm dx=\frac13(-e^{-x})\bigg|_0^3=\frac13(-e^{-3}-(-e^{-0})) = \frac13 \left(1-\frac1{e^3}\right) = \boxed{\frac{e^3-1}{3e^3}}$
