Solve by factoring the equation x^2+36=12x

1 answer:

6 0

$x^2+36=12x\\\\x^2-12x+36=0\\\\x^2-6x-6x+36=0\\\\x(x-6)-6(x-6)=0\\\\(x-6)(x-6)=0\\\\(x-6)^2=0\iff x-6=0\Rightarrow\boxed{x=6}$

For f(x) = 0.01(2)x, find the average rate of change from x = 2 to x = 10.

kenny6666 [7]

$\bf slope = m = \cfrac{rise}{run} \implies 
\cfrac{ f(x_2) - f(x_1)}{ x_2 - x_1}\impliedby 
\begin{array}{llll}
average~rate\\
of~change
\end{array}\\\\
-------------------------------\\\\
f(x)=0.01(2)^x \qquad 
\begin{cases}
x_1=2\\
x_2=10
\end{cases}\implies \cfrac{f(10)-f(2)}{10-2}
\\\\\\
\cfrac{0.01(2)^{10}~~-~~0.01(2)^2}{8}\implies \cfrac{10.24~~-~~0.04}{8}\\\\\\ \cfrac{10.20}{8}\implies 1.275$
