The zeros of the function f(x)=3x^2-3x-6 are

1 answer:

3 0

F(x) = 3x² - 3x - 6

The zeros f(x) = 0 ⇒ 3x² - 3x - 6 = 0

3x² - 6x + 3x - 6 = 0

3x(x - 2) + 3(x - 2) = 0

(x - 2)(3x + 3) = 0 ⇔ x - 2 = 0 ∨ 3x + 3 = 0

x = 2 ∨ 3x = -3

x = 2 ∨ x = -1

Answer:

93.5 square units

Step-by-step explanation:

Diameter of the Circle = 12 Units

Therefore:

Radius of the Circle = 12/2 =6 Units

Since the hexagon is regular, it consists of 6 equilateral triangles of side length 6 units.

Area of the Hexagon = 6 X Area of one equilateral triangle

Area of an equilateral triangle of side length s = $\dfrac{\sqrt{3} }{4}s^2$

Side Length, s=6 Units

$\text{Therefore, the area of one equilateral triangle =}\dfrac{\sqrt{3} }{4}\times 6^2\\\\=9\sqrt{3} $ square units$

Area of the Hexagon

$= 6 X 9\sqrt{3} \\=93.5$ square units (to the nearest tenth)$
