Earthquake measuring 4.5 is 10 times more powerful than earthquake measuring 3.5 on Richter scale.
Step-by-step explanation:
Earthquake refers to the violent shaking of the Earth crust in response to its extremely dynamic interior. Sometimes the rocks are loaded or stressed beyond its elastic limit, following which it rebounds thus emitting a wave(seismic), which is received by us as seismic waves.
The energy released during an earthquake is measured in Richter scales (named after Charles Richter). While 1 is the lower limit, there is no such upper limit. However, earthquakes above 7 are considered fragile for human existence. It is a logarithmic scale meaning successive numbers of the scale by a factor of 10.
Thus, an earthquake measuring 4.5 would be around 10 times more powerful than an earthquake measuring 3.5 following logarithmic scale.

Answer:
Point-slope,standard form,slope intercept form.
Step-by-step explanation:
Answer:
Lower boundary of 46 = 33
Lower boundary of 59 = 47
Lower boundary of 72 = 60
Lower boundary of 85 = 73
Step-by-step explanation:
Since the difference between each of the two successive numbers is 13. This implies that the difference between the upper and the lower boundaries for each of the class is 12.
Therefore, we have to subtract 12 from each of the upper boundary given the question to obtain their lower boundary as follow:
Lower boundary of 46 = 46 - 12 = 33
Lower boundary of 59 = 59 - 12 = 47
Lower boundary of 72 = 72 - 12 = 60
Lower boundary of 85 = 85 - 12 = 73
Note:
It can be observed that the lower boundary of each upper can also be obtained by adding 1 to the immediate previous upper boundary. But, we adopt the above method in order to get the lower boundary of 46 since there is immediate previous upper boundary for 33 that is included in the question. With the method used above, one get as many lower and upper boundaries as one wants.
