Suppose c is inversely proportional to the square of d. If c=6 when d=3⁢, find the constant of proportionality and write the formula for c as a function of d?
c= ?
How would I write the formula?
Use your formula to find c when d is 7.

Enter the exact answer.
c=?
What would c equal?

The constant of proportionality is 54.

k = 54

c as a function of d:

Step-by-step explanation:

We are given the following in the question:

c is inversely proportional to the square of d.

When c = 6, d = 3.

Plugging the values, we get,

Thus, the constant of proportionality is 54.

c as a function of d can be written as:

We have to find value of c when d = 7.

Putting values, we get,

is the required value of c.

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480
