Choose the statement that is true. Exoplanets can be observed by the reflected light they give off from their star much the same way we can observe Mars, Venus and Jupiter.
It is estimated that 50% of the estimated 100 billion stars in the Milky Way galaxy have 5 or more planets.
The radial transit method of detecting star wobble registers the amount of red shift and blue shift and blue shift detectable in the star's movement as it moves away from us or towards us.
The habitable zone is where stars and planets are not threatened by either supernovas exploding or from being swallowed by black holes.

Project information: the pythagorean theorem can be used in many real-world scenarios. the following is an example of real-word scenario where you will use the pythagorean theorem to find the missing piece. real-word scenario: a handyman needs to create triangular trusses to frame out the roof of a small shed. he knows the roof itself will be 9 feet tall and the length of each truss will be 14 feet. how long will the roof be from its highest to lowest point? part 1: the handyman created a drawing to provide a visual to solve this problem. below is his drawing. 1. part 2: solve the real-life scenario. show all your steps in answering the question and make sure you label your final answer correctly.
