Answer:
Y = 125
Step-by-step explanation:
Y is directly proportional to X^2
Mathematically,
Y ∝ X²
Y = kX²
Where k = Constant of Proportionality
Step 1
If y = 45 when x = 3
We solve for k
Y = kX²
k = Y/X²
k = 45/3²
k = 45/9
k = 5
Step 2
find y when x = 5
Y = kX²
k = 5, X = 5
Hence,
Y = 5 × 5²
Y = 125
