Answer:
(A) 999 734 198.4
B) 9999043.54
C) the intensity L is squared when R is doubled
D) dR/dL = 1/(Lln10)
Step-by-step explanation:
R = (In L - ln Lo)/ ln 10
Since Lo = 1 and ln 1 = 0
Therefore,
R = ln L / ln 10
(A) Since R = 9
In L = Rln10
In L = 9 ln10 = 20.723
L = exp(20.723) = 999 734 198.4
Therefore, the intensity of earthquake in Japan = 999 734 198.4
(B) when R = 7
In L = Rln10
In L = 7ln10 = 16.118
L = exp(16.118) = 9999043.54
Therefore the intensity of earthquake in Haiti = 9999043.54
(C) when R is doubled, let say R = 14
L= exp(14ln10) = 99980871640000
Then the ratio of L(R=14) and L(R=7)
L(R=14)/L(R=7) = 99980871640000/9999043.54 = 9999043.53
Since L(R=14)/L(R=7) = L(R=7)
Therefore, the intensity L is squared when R is doubled
D) R = lnL/ln10
dR/dL = 1/(Lln10)
Answer:

Answer:
Step-by-step explanation:
- Let the pants cost = p
- Skirts cost = s
<u>We got equations</u>
<u>Substituting p and solving for s</u>
- 6s = 4(s + 5) - 4
- 6s = 4s + 20 - 4
- 6s - 4s = 16
- 2s = 16
- s = $8
