What is the domain of this function?

Oxana [17]

Answer:
{x | x > 8}

Explanation:
On the graph, the left end has a dot on x = 0, not an arrow, so the graph does not reach left of x = 0.

On the right end, there is an arrow where x = 8, which means the graph continues past x = 8.

A cone has a diameter of 6 cm and a height that is 3 times the diameter. Using 3.14 for pi, which of the following can be used t

Zinaida [17]

Option A: 1/3(3.14)(3cm)^2(18cm) is the correct answer

Step-by-step explanation:

Given

Diameter of Cone = d = 6 cm

Radius will be:

r = d/2 = 6/2 = 3 cm

Height of cone = h = 3d = 18 cm

The volume of cone is given by:

$V = \frac{1}{3}\pi r^2h$

Putting the values

$V = \frac{1}{3} (3.14)(3)^2(18)$

Hence,

Option A: 1/3(3.14)(3cm)^2(18cm) is the correct answer

Derivative of g(x) = 3x^2(x^2-(2/x))

Elza [17]

When you are doing derivatives, you don't want to do it right away because there is still ( ) we need to remove that first get,

g(x)=3x^4-6x

Now we can do the derivatives!

g(x)=12*x^3 - 6

I hope this helps!

RideAnS [48]

Answer:

a=22.6549

Step-by-step explanation:

Calculated based on 2 given angles and 1 given side.

∠C = 180° - A - B = 0.99484 rad = 57°

a = c·sin(A)/sin(C) = 22.6549

b = c·sin(B)/sin(C) = 12.33874
