9. The Richter scale is used to measure the magnitude of an earthquake. The magnitude, R.
is given by the equation
R = 0.65log (0.392) +145
where E is the energy (measured in
kilowatt-hours) released by the earthquake. Determine the amount of energy released by an
earthquake of magnitude 7.5.
Part I: Rewrite the equation for the magnitude of an earthquake, using the magnitude of
7.5 given in the problem. (2 points)
Part II: Simplify the problem so that it is written in the form b= loga (4 points)
I
Part III: Solve the problem for E, the energy released by the earthquake (6 points)

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n β 1) + 4; n > 1 f(1) = 4 and f(n) = f(n β 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n β 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n β 1) + 2; n > 1 i will award !
