Answer:
A3tx-A2b=cdx-2c
Step-by-step explanation:
Distribution
The answer is 28 years
At = A0 * e^(-k * t)
At = 12 g
A0 = 15 g
k = 7.9 × 10^-3 = 0.0079
t = ?
12 = 15 * e^(-0.0079 * t)
12/15 = e^(-0.0079 * t)
0.8 = e^(-0.0079 * t)
Logarithm both sides (because ln(e) = 1:
ln(0.8) = ln(e^(-0.0079 * t))
ln(0.8) = (-0.0079 * t) * ln(e)
-0.223 = -0.0079 * t
t = -0.223 / -0.0079
t = 28.23
t ≈ 28 years
Answer:16???
Step-by-step explanation:
Answer:
1.5
Step-by-step explanation:
2 ft. / the number of sides for width (2) = 1 then 3 ft. / number of sides for length (2) = 1.5
1.5 x 1 = 1.5
