There are a number of reasons why it is necessary to open and close the air vents. These include; allowing oxygen in, which is also necessary for respiration and allowing heat to escape. Closing the ai...
y is proportional to x2 so this means y = A*x2 for some constant A.
When y = 75, x = 5. Put these values in the formula above to find A:
75 = A*25
To differentiate x2 you bring the power of x down, then reduce the power of x by 1, so d/dx(x2) = 2x1
ln3x differentiates to (d/dx(3x))/3x = 3/3x = 1/x
