Answer:
A. 2.1
Step-by-step explanation:
Put the numbers in the equation and do the arithmetic.
1/R = 1/(3 1/2) +1/(5 1/4)
1/R = 1/(7/2) +1/(21/4) = 2/7 +4/21 = (6 +4)/21
R = 1/(10/21) = 21/10
R = 2.1
We can set up a proportion.
2/3 = x/1
Cross multiply.
2 * 1 = 2. 3 * x = 3x, so we have 3x = 2.
Now we can divide 3 by 2 to get our answer, which is 1.5. :)
angle CBD and angle BFE are congruent because they are corresponding angles.
angle ABF and angle BFE are congruent because they are alternate interior
angles.angle CBD and angle ABF are congruent because they are vertical angles.

Answer:
25.5 years
Step-by-step explanation:
The multiplier for continuous compounding at annual rate r for t years is ...
e^(rt)
You want the value of t when that is 3 and r=0.043.
3 = e^(0.043t)
ln(3) = 0.043t
t = ln(3)/0.043 ≈ 25.549 . . . . years
