1/2 to the second power I'm sure is 1/4
Answer:
C is the right answer.
2y x 4 = 8y
2 x 4y = 8y
Let me know if this helps!
I think the length is 192 and the width is 64 but i’m not 100% sure
Answer:
33x - 13 = 13x + 7
Step-by-step explanation:
If "G" is the midpoint of line FH, then both segments (lines FG and GH) must be the same length. Therefore, to find "x", you can set both segments equal to each other. After doing this, you can simplify and isolate to find "x".
FG = 33x - 13
GH = 13x + 7
FG = GH
33x - 13 = 13x + 7
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)
