I'd go with your third option, 6.

Half the diameter (the radius, also the hypotenuse for the right triangle) is 10 units.

Half of the chord given by that blue line segment is 8 units. Now we do the Pythagorean Theorem (a² + b² = c²) to find the length of x.

x² + 8² = 10²
x² + 64 = 100
x² = 36
√x² = √36
x = 6

Find the range of the function y=-x^2-3x when the domain is {-5,0,2}

umka21 [38]

Answer: $\{-10, 0 \}$

Step-by-step explanation:

The range is the set of output values for the domain (the set of inputs).

When x=-5, y= $-(-5)^{2}-3(-5)=-10$ .
When x=0, $y=-0^{2}-3(0)=0$ .
When x=2, $y=-2^{2}-3(2)=-10$

So, the range is $\boxed{\{-10, 0 \}}$

Can anyone please explain? Need some help :)

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)$
