The shaded area = the arced area - the area of the triangle

The arced area = (120/360) * pi * 6^2 = 12pi

The height of the triangle is 6*sin60 = 3√3

So the area of the triangle is 1/2 * 6 * 3√3 = 9√3

So the shaded area = 12pi - 9√3

k = -4 ± 2√5

Step-by-step explanation:

#22

<h3>Given </h3>

Equation x² -4x + 1 = k(x - 4) with equal roots

The value of k

<h3>Solution</h3>

<u>The equation in standard form is:</u>

x² -4x + 1 = k(x - 4)
x² - 4x - kx + 1 + 4 = 0
x² - (k + 4)x + 5 = 0

<u>When the quadratic equation has equal roots its discriminant is zero</u>

D = 0
b² - 4ac = 0
(k + 4)² - 4*5 = 0
(k + 4)² = 20
k + 4 = ± √20
k = - 4 ± √20
or
k = -4 ± 2√5
