Step 
we know that
The density's formula is equal to
The volume of a cone is equal to
where
r is the radius of the base of the cone
h is the height of the cone
in this problem
substitute the values in the formula above
Step 
Find the density
we have
substitute in the formula
therefore
<u>the answer is</u>
the density is 
Unfortunately you have not included the directions. Are you supposed to solve for x? or for y?
Suppose the directions say, "Solve for x." Then, clear out the decimal fraction by mult. both sides of the given equation by 10. This will give you the solution, that is, a formula for x in terms of y.
The simplified expression of the complex number 6! - 3! is another complex number 6i(1 - 0.5)
<h3>How to simplify the expression?</h3>
The complex number expression is given a:
6! - 3!
Factor out i from the expression
6! - 3! = i(6 - 3)
Factor out 6 from the expression
6! - 3! = 6i(1 - 0.5)
The above means that the simplified expression of the complex number 6! - 3! is 6i(1 - 0.5)

Answer:
![y=2sin[\frac{\pi}{4}(x+3) ]-5](https://tex.z-dn.net/?f=y%3D2sin%5B%5Cfrac%7B%5Cpi%7D%7B4%7D%28x%2B3%29%20%5D-5)
Step-by-step explanation:
The standard form for a sinusoidal function is given by:
y = Asin[B(x - C)] + D
Where A is the amplitude of the sine wave, the period is 2π/B, C is the phase shift and D is the vertical displacement / translation
Given:
A = 2, D = -5 (down), C = -3 (left).
8 = 2π/B; B = π/4
Therefore:
Hey there! I'm happy to help!
Don't let this negative on the outside freak you out. It just means -1. We want to multiply everything on the inside of the parentheses by -1 to simplify.
-1(5.8a)=-5.8a
-1(4.2b)=-4.2b
So, our final expression is -5.8a-4.2b.
Have a wonderful day! :D
