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 .
Actually, the answer is not A, if you're saying A is the first choice above. That's incorrect. You will need to use the Geometric mean for right triangles here to figure out what the value of a is. We will use this form: 
. We have a value for YZ of 3; side a is XZ. That means in order to solve this we need WZ, which we can find using pythagorean's theorem. 3^2 + 4^2 = c^2 and 9 + 16 = c^2 and c = 5. Now we fill in accordingly: 
. Cross-multiply to get 3XZ=25 and side XZ is 
. XZ is 25/3 and YZ is 3, so 25/3 - 3 = XY. That means that XY (side a) = 16/3 or 5 1/3, choice B, or the second one down.
