Answer:
c = 360/n
Step-by-step explanation:
From the question, we are told that:
The cost per ounce of a drink, c, varies inversely as the number of ounces, n.
Mathematically this is expressed as:
c ∝ 1/n
Using the constant of proportionality k
c = k/n
Six ounces of the drink costs 60 cents per ounce.
c =60 cents per ounce
n = 6 ounces
Mathematically we have
c = k/n
60 = k/6
Cross multiply to find the constant k
k = 60 × 6
k = constant of proportionality = 360
Therefore, using the mathematically expression "c = k/n" the equation that represents this relationship is
c = 360/n

<u>Example</u>
y = x^2 + 3x . . . . . we want y' at (x, y) = (1, 4)
y' = 2x +3 . . . . . . . take the derivative dy/dx of the function
Fill in the value x=1 ...
y' = 2·1 +3 = 5
The value of the derivative at (x, y) = (1, 4) is 5.

Step-by-step explanation:
It isn't clear what is supposed to go in the various blanks. We have elected to identify the corresponding congruent parts, and name the congruent triangles. The postulate supporting the conclusion is also shown.
In most cases, corresponding parts are marked congruent. The exception is the vertical angles in figure 22.

Answer:
It represents the cost of the DVD player.
____________________________________________________
Step-by-step explanation:
The reason why it represents the cost of the DVD player is because in the question, it doesn't mention anything about buying multiple DVD players. Ebony would need to buy many DVD's, but doesn't need many DVD players because ebony could use one for all of the DVD's. If you noticed in the question, it says "a DVD player," what this means is that Ebony is only going to buy one DVD player, since it's singular (without and s at the end).
The equation is saying that she starts off with buying 1 DVD player for 200 dollars; and, she is buying n (number of DVDs) for 20 dollars each.
This shows that the 200 in the equation in the question represents the cost of the DVD player.
