Given f(x)=x^2+12x+26.

MA_775_DIABLO [31]

Answer:

f(x) = (x+6)² - 10

Step-by-step explanation:

To write the equation in vertex form we, we need to use completing square method.

f(x) = x²+ 12x + 26 = (x² + 2*x*6 + 6²) - 6² + 26 = (x+6)² -36 + 26 =

= (x+6)² - 10

f(x) = (x+6)² - 10

John is walking around a circular track with a radius of 50 ft. If he walks the equivalent of 140 degrees, find the total distan

Vera_Pavlovna [14]

Answer: 122 ft

<u>Step-by-step explanation:</u>

s = r Ф (Ф must be in radians)

Given: r = 50

Ф = 140°

$\dfrac{\pi}{180^o}=\dfrac{x}{140^o}$

$\dfrac{140^o\pi}{180^o}=x$

$\dfrac{7\pi}{9}=x$

$s=50\bigg(\dfrac{7\pi}{9}\bigg)\\\\\\.\quad =\dfrac{350\pi}{9}\\\\\\.\quad =122\ ft$
