James is researching earthquakes for a science report. he is trying to come...
the answer is B) logarithmic
In the given situation, James wants to find a way to distinguish between a very small intensity, x, and a very large intensity, y. To plot this with most graphs, it would involve using an axis that has a magnitude range of several hundred thousand. However, a logarithmic function allows for a single digit change to represent an increase in magnitude by a factor of ten.
Therefore, the situation is best modeled by a logarithmic function.
(sin 42)/31. = sinx)/37
sinx = 37 (sin42)/31
= 37× 0.66/31 = 0.787
other angle opposite to y = 180-51.9-42
= 180- 93.9 =86.1
sin42)/31 = sin 86.1)/y
0.021 = 0.997 /y
y= 0.997/0.021 =47.47
