Stephanie casts a shadow of 1.2 m and she is 1.8 m tall. A wind turbine casts a shadow of 10m at the same time that Stephanie me
asured her shadow. Draw a diagram of this situation
and then calculate how tall the wind turbine is.
1 answer:
Answer:
- see below for a diagram
- 15 m
Step-by-step explanation:
Stephanie is 1.8/1.2 = 1.5 times as tall as her shadow is long. We expect the same is true of the wind turbine.
The wind turbine's shadow is 10 m long, so its height is 1.5·(10 m) = 15 m.
The wind turbine is 15 m tall.

y = a(x - b)^2 + c has vertex (b , c)
so here the vertex is (1, -36)
