There are 8 vertices in a rectangular prism. An easy way to remember that is the number of vertices on the 2 end squares when combined, as they are shared with the side faces<span />
To find the epicenter (the point on the earth's surface where an earthquake begins) during earthquakes, one need to view the seismogram (a record of the ground motion), and at least two other seismographs recorded for the same earthquake. Other instruments such as a map, a compass for sketching circles on the map, a ruler, and a pencil will also be used.
The following are the steps of the triangulation process in the correct order to find the epicenter during earthquakes:
Step 1: Subtract the time of P wave arrival from S wave arrival.
Step 2: See what the time difference is equal to in distance on a seismic wave chart.
Step 3: Draw circles representing the distances from at least three seismograph stations to the epicenter on a map.
Step 4: Find the point where all 3 circles intersect, and you've found the earthquake's epicenter.
The answer is -2 because you divide the rise by run
The answer is: D. How regions differ from each other
Answer:
21
Explanation:
y=mx+b
mx = slope and b= y intercept
y=5-21
