Answer 1

Answer:

Question:-

y is inversely proportional to d²

When d = 10, y = 4

d is directly proportional to x²

When x = 2, d = 24

Find a formula for y in terms of x.

Give your answer in its simplest form.

Solution:-

y=k/d^2

substituting:4=k/102

4=k/100

400=k

d=nx^2

substituting:24=n x 2^2

24=4n

n=6

Eq1:y=400/d^2

Eq2:d=6x^2

y=400/(6x^2)

y=400/36x^4

y=200/13x^4
