The answer to the problem is A
Whereas the density of the hemisphere at any point is proportional to it's density, then
The full answer in attachment, we use the partial integral using the <span>spherical coordinates,
and we find that </span>the mass of h = <span>πK/2</span>
The given functions are


Now these are exponential curves and the bases for the functions are 3.5 & 1.5
Also the graph of g(x) is between f(x) & h(x)
Hence the value of base called the scale factor must be between 3.5 & 1.5.
4 & 5 are more than 3.5
0.9 is smaller than 1.5
But π = 3.14 lies between 3.5 & 1.5.
Hence the only option which can represent the graph of g(x) is

Option D) is the right answer
Answer:
5 is greater than equal to 5. So f(5)=5+8=13
