1 and 3, same explanation as last time
Use arithmetic sequence in order to get to answer:
a_n= a₁ rⁿ⁻¹
r is a common ratio, a₁ is the first term and a_n is the summation.
a_n= 1 (2/1)¹⁵⁻¹= 16384 pennies

Answer:
1/3
Step-by-step explanation:
F = 36
G = 4
We know that The area is multiplied by the scale factor squared
F * (SF) ^2 = G
36 (SF) ^2 = 4
Divide each side by 36
36/36 (SF) ^2 = 4/36
(SF) ^2 = 1/9
Take the square root of each side
sqrt((SF)^2) = sqrt(1/9)
SF = 1/3
The scale factor is 1/3
Answer:
40 years after 1982, there is 396.85 kilograms of radioactive element remaining. The area will not be safe for human habitation by 2022.
Step-by-step explanation:
We are given the following in the question:
where f(x) is the amount of normal curve cannot be used as an approximation to the binomial probability. in kilograms x years after 1982.
We have to approximate f(40)
Putting x = 40, we get
Thus, 40 years after 1982, there is 396.85 kilograms of radioactive element remaining.
With 100 kilograms of radioactive material, the area is unsafe for humans.
Thus, the area will not be safe for human habitation by 2022.
