All identities are equations, but ONLY SOME equations are identities.
sinx = cos(π/2 - x) (Equation and Identity
y= cosx -x², it's an equation but NOT an identity
Log(2)/log(1.064) ≈ 11.17 . . . . hours
_____
The population can be given by
p(n) = p₀×1.064ⁿ . . . . where n is the number of hours
You want to find n whe p(n) = 2*p₀.
2p₀ = p₀×1.064ⁿ . . . . . . . . . . . . substitute the given information
2 = 1.064ⁿ . . . . . . . . . . . . . . . . . divide by p₀
log(2) = n×log(1.064) . . . . . . . . take logs to make it a linear equation
log(2)/log(1.064) = n . . . . . . . . divide by the coefficient of n
To find the difference you simply have to subtract 43% from 57%
57% - 43%
14% is your answer
Hope this helps!
Im guessing those are those brackets?
15 hrs a week at 8.95 per hr = (15 * 8.95) = 134.25 gross pay
FICA (7.65%)....0.0765(134.25) = 10.27
fed.tax (9.3%)...0.093(134.25) = 12.49
state tax (5.8%)..0.058(134.25) = 7.79
total taxes : 10.27 + 12.49 + 7.79 = 30.55
savings account money = 30
134.25 - (30.55 + 30) =
134.25 - 60.55 = 73.70...its gonna be the last one because I did a little rounding up above
