What happens to the density as the volume approaches 0?
The density approaches 13.
Assume : V = 3 ; V = 2 ; V = 1
D = 13/3 = 4.33
D = 13/2 = 6.50
D = 13/1 = 13
Answer:
Option A is correct
The density approaches infinity.
Step-by-step explanation:
Given the equation:
....[1]
where,
D is density of a particular substance .
v is the volume of the substance.
We have to find What happens to the density as the volume approaches 0.
As the volume approaches to 0
⇒
[1] ⇒
⇒The density approaches infinity.
Therefore, the density as the volume approaches 0 is, infinity.

-- The function is a sine or cosine that wiggles from 3 below to 3 above its average value. So the amplitude is 3 . That lets out the 1st and 3rd choices.
It has to be the 2nd or 4th choice.
Looking at the graph, the y-intercept is at y=6.
The y-intercept is the point where x=0, so f(0)=6.
Test the 2nd choice: f(x) = 3 cos(x) + 3
f(0) = 3 cos(0) + 3
cos(0) = 1 so f(0) = 3 (1) + 3 = 6
Choice-2 is looking good.
Just to be sure, let's check choice-4:
f(x) = 3 sin(x) + 3
f(0) = 3 sin(0) + 3
sin(0) = 0 so f(0) = 3 (0) + 3 = 3
Beautiful ! Choice-4 flopped. The answer is choice-2 .

Answer:
y = -1.2x² +6.6x +2
Step-by-step explanation:
The quadratic regression function of a calculator or spreadsheet can do this for you. The resulting function is ...
y = -1.2x² +6.6x +2
_____
If you want to do this by hand, put the given (x, y) values into the formula ...
ax² +bx +c = y
and solve the resulting system of equations.
The third point tells you c=2, so you can simplify the system of equations to ...
a(-2)² +b(-2) +2 = -16 ⇒ 4a -2b = -18 ⇒ 2a -b = -9
a(3)² +b(3) +2 = 11 ⇒ 9a +3b = 9 ⇒ 3a +b = 3
Adding these equations together gives ...
(2a -b) +(3a +b) = (-9) +(3)
5a = -6 . . . . . . . . simplify
a = -1.2 . . . . . . . divide by 5
b = 3 -3a = 3 -3(-1.2) = 6.6 . . . . from the second equation
Now we know the coefficients are a=-1.2, b=6.6, c=2, so the function is ...
y = -1.2x² +6.6x +2
