question please

Step 2 We must find dy/dt. The equation found in the previous step can be re-written as follows. 24 24 y X -1 -1 - 24X Step 3 Now find dy dt dy 24 24 dx dt x dt 72 Step 4 Substituting x = 8 gives us the following. (Round your answers to one decimal place.) dy _ (-24) 8 X dt 64 = -3/4 The shadow is decreasing at a rate of -0.6 X m/s.A spotlight on the ground shines on a wall 12 m away. If a man 2 m tall walks from the spotlight toward the building at a speed of 2.2 m/s, how fast (in m/s) is the length of his shadow on the building decreasing when he is 4 m from the building? Step 1 Using the diagram below, nd the relation between x and y. 2: L .i/ 7 12 '/ E
