Answer:Values for the coefficient in the product k:
, so the first four boxes should be filled with the number "3"
Drop down arrow: "does"
Step-by-step explanation:
We perform all the products of wavelength time frequency indicated for the column of the quantity "k":
=
=
Therefore, all products of these different wavelengths and their associated frequencies render the exact same answer : 
, which means that as one of these quantities increase, the other one will decrease in the same proportion to give the same numerical answer.
This means that the two quantities are associated via inverse proportionality. As seen in the equation below, if the quantities "x" and "y" are related by inverse proportionality (shown as one equals a constant "A" divided by the other variable), their product x*y will give that constant value "A" (which in our case is .
-5x=-35
divide both sides by -5
-5x/-5 = -35/-5
simplify
x = 7
100% of the price = $400
x % of the price = $320
we need to find x
using a proportion
100 : 400 = x : 320
100 * 320 = 400 * x
32000 = 400x
x = 32000 / 400
x = 80
That means the new price is 80% of the previous price.
100% - 80% = 20%
and based on this we can make a conclusion that the discount was 20%
I hope it is clear to you, feel free to ask anything about it :)
