A man 2 m high observes the angles of elevation of the t ops of house and a window on its side are 45 and 60 respectively. If the top is at height of 12m above the ground , find the height.

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.
