24,-12,6,-3,_,_,_,_,_ ?

 

Answer:

Geometric Sequence

an=a1(r)^(n-1)

r=-1/2

an=24(-1/2)^(n-1)

Find

a5,a6,a7,a8,a9

an=24(-1/2)^(n-1)

a5=24(-1/2)^(5-1)

a5=(1/16)(24)

a5=3/2

a6=24(-1/2)^(6-1)

a6=(-1/32)(24)

a6=-3/4

a7=24(-1/2)^(7-1)

a7=(1/64)(24)

a7=3/8

a8=24(-1/2)^(8-1)

a8=(-1/128)(24)

a8=-3/16

a9=24(-1/2)^(9-1)

a9=(1/256)(24)

a9=3/32

The Differents Steps In Triangulation Method

The differents steps in triangulation method   Here are the steps in finding the epicenter using the triangulation method: 1. Get data from the 3 seismic station with regards to the seismic waves. 2. Identify the time difference in the arrival of p-wave and s-wave. 3.Base on the time difference (in seconds) in the arrival of p-wave and s-wave, we can use the formula distance = TD (time difference) / 8 seconds   ×  100 km to find the distance of the epicenter in each recording station. You will also using the scaling depending on the Map you used to find the epicenter of an earthquake. 4. Use triangulation technique using your pencil, Map, and drawing compass. Note: The location of the epicenter will be on the point wherein the three lines are intersecting as you illustrate it using your compass and pencil. Example: Recording station                TD (time difference)            Distance Davao                                            30  s                                375 km
