SOLUTION: P is inversely proportional to d^2 P = 10,000 when d = 0.4 Find the value of P when d = 0.8 I know that P = k/ d^2 so .. k/ 0.64 = 10,000 but i dont know how to use the n

Question 567594: P is inversely proportional to d^2
P = 10,000 when d = 0.4
Find the value of P when d = 0.8
I know that P = k/ d^2
so .. k/ 0.64 = 10,000
but i dont know how to use the numbers given to find the value

P is inversely proportional to .
Given that when make the substitutions:
Solve for k:

so...
now substitute
Evaluate.
