Answer:
2556 feet squared
Step-by-step explanation:
Area is calculated by multiplying length times width. 71x36=2556
N + (n+1) + (n+2) = -369
3n + 3 = -369
3n = -366
n = -122
so the three consecutive integers are : -124 ; -123 ; -122
If the half-life is t, then every t days, the amount of the radioactive isotope will be cut in half.
(1/2)^(number of half-lives) = 3%
number of half-lives = ln(0.03) / ln(0.5)
This gives the number of half-lives as 5.06.
Then 300 days = (5.06)(length of 1 half-life)
length of 1 half-life = 300 / 5.06 = 59.29 days
Answer:
|1/2x - 20| ≥ 2
Step-by-step explanation:
The number is half of two and at least two units away.
3/8 meters squared because 3/4x1/2 = 3/8m
