3p=p(1+0.06)^t
3=(1.06)^t
T=log(3)÷log(1.06)
T=18.9 years
Answer:
C.) -2
Step-by-step explanation:
solve by putting 12 in for f(x)
12 = 2(x + 8)
Divide by 2
6 = x + 8
Subtract 8
-2 = x
1 mile = 1760 yards
1 squre mile = 1760^2 yd^2 = 3097600 yd^2
This means that
Each acre has (3097600 yd^2/ sq. mile ) / (640 acres/sq. mile(= 4840 yd^2 / acre
Also, we know that 1 inch = 2.54 cm exactly.
Therefore
1 yd = 3*12*2.54 cm = 91.44 cm = 0.9144 m
1 yd^2 = (0.9144 m)^2 = 0.83612736 m^2
Using the conversion from acre to sq yards,
1 acre=4840 yd^2
=4840 yd^2 * 0.83612736 m^2 / yd^2
= 4046.8564224 m^2
Answer: 1 acre = 4046.8564224 m^2
