Ameter stick casts a shadow 2.4 m long at the same time a flagpole casts a shadow 9.7 m long. how tall is the flagpole

The first thing we are going to do is draw a diagram of the situation to help us to solve the situation.
We an draw tow similar triangle between the length of the shadows and the height of the stick and the pole.
Since meter stick has a length of 1 meter, the height of our smaller triangle is 1 meter. Let  be height of of the pole. Since both triangles are similiar we can establish a proportion between their corresponding sides and solve for :




We can conclude that the pole is 4.04 meters tall. 

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
