Answer:
The value of y is 847 for x=11
Step-by-step explanation:
It is given that y is directly proportional to the square of x
This can be written mathematically as:
Removing the proportionality symbol introduces a proportionality constant in the equation which is denoted by k
Given that "When x is 5, y is 175"
Putting the value of k
Now putting x = 11
Hence,
The value of y is 847 for x=11
