A.(x - 3)
Step-by-step explanation:
Answer:
38
Step-by-step explanation:
Replace all the variables with the given numbers:
(5)²+2(8)÷2(2)+3(3)
Multiply the numbers to get the final equation:
25+16÷4+9
Solve:
25+16÷4+9=38
Answer:
Step-by-step explanation:
<u>Given:</u>
- Initial population = 6.08 billion
- Increase rate = 1.5% or 0.015 times per year
Time passed = 2017 - 2000 = 17 years
<u>Population in 2017:</u>
- P = 6.08*(1 + 0.015)^17 = 7.8 billion
The elevations of four points below sea level are -47 feet, -24 feet, -8 feet, and -18 feet.
The elevation of the point closest to sea level is feet
-8 ft
elevation of the point farthest from sea level is feet.
-47 ft
closet to sea level to farthest to sea level
-8ft , -18ft , -24ft , -47ft
Answer:
18 minutes
Step-by-step explanation:
A = A₀ (½)^(t / T)
where A is the final amount,
A₀ is the initial amount,
t is the time,
and T is the half life.
A = 140 when t = 10. Solve for the half life:
140 = 700 (½)^(10 / T)
0.2 = ½^(10 / T)
log 0.2 = (10 / T) log 0.5
10 / T = 2.32
T = 4.31
When A = 40, t is:
40 = 700 (½)^(t / 4.31)
0.057 = ½^(t / 4.31)
log 0.057 = (t / 4.31) log 0.5
t / 4.31 = 4.13
t = 17.8
Rounded to the nearest whole number, it takes 18 minutes.
