Answer:
When x = 5, y = 1.44
Step-by-step explanation:
We know that when 'y' varies inversely with 'x', we get the equation
y ∝ 1/x
y = k/x
where 'k' is called the constant of proportionality
In our case, given that y varies inversely as the square of x.
so
y ∝ 1/x²
y = k/x²
When x = 3, y = 4, we need to find k
y = k/x²
k = yx²
k = 4(3)²
k = 36
so, the value of k = 36
Now, we need to find y when x = 5
so substitute k = 36, x = 5 in the equation
y = k/x²
y = 36 / (5)²
y = 36 / 25
y = 1.44
Therefore,

Answer is A. the first fraction can be simplified to -16, second to -4.5. a negative divided by a negative is a positive, and 3.56 can be rounded to 4.
