Step-by-step explanation:
Log T = 11.8 + 1.5.M (with T is the amount of energy released by the earthquake, Log refers to the logarithm to the base 10)
-->T = ≈3.458 *
Answer: 2.00 x 10¹⁰⁹
<u>Step-by-step explanation:</u>
log T = 11.8 + 1.5M
Given: M = 6.5
log T = 11.8 + 1.5(6.5)
log T = 11.8 + 9.75
log T = 21.55
T = 10²¹⁻⁵⁵
T = 1.995 x 10¹⁰⁹
T = 2.00 x 10¹⁰⁹ <em> rounded to the nearest hundredth</em>
Thanks again you are VERY sweet and kind!
Answer:
The radius is equal to 6.5 feet.
To solve this we need to know that circumference equals 2πr (where "r" is the radius). Therefore, we can make the following equation...
2πr = 40.82
πr = 20.41
3.14r = 20.41
r = 6.5
Now we know that the radius is equal to 6.5 feet.
