Atree that is 100 feet tall casts a shadow that is 150 feet long. determine the angle at which the rays of the sun hit the ground, to the nearest degree.

The ratio of the tree height to shadow length is 23

So the angle of the sun is θ=arctan(23)

and with the aid of a calculator, θ≈33∘

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
