The value of b is one. You just have to use the standard equation y = a + bx^2 + c. Get a, b, then c and from the given equation above you can derive a formula which is x is equal to the - b over 2 multiplied by a. if you get the value of x then substitute it to the equation and you will now get the value of b.
Earthquakes with a magnitude of 3 are usually not felt or are only felt by a few people at rest (mostly on higher floors of buildings).
Answer: <M corresponds to <J
<L corresponds to <O
JL corresponds to MO
To find the corresponding angles:
1. Look at the figures.
<M is to <J, <N is to <K, and <O is to <L.
2. Look at the similarity statement.
ΔMNO ~ ΔJKL. <M is to <J because they are the first letters.
ΔMNO ~ ΔJKL. <N is to <K because they are second letters.
ΔMNO ~ ΔJKL. <O is to <L because they are third letters.
Apply these two methods to find the corresponding sides.
