Answer:
Would you mind posting a picture instead thank you.
To solve this we are going to use the half life equation

Where:

is the initial sample

is the time in years

is the half life of the substance

is the remainder quantity after

years
From the problem we know that:



Lets replace those values in our equation to find

:




We can conclude that after 1600 years of radioactive decay, the mass of the 100-gram sample will be
91.7 grams.
Answer:
131ft is the amount of fencing material needed
Step-by-step explanation:
Perimeter is the distance around a shape: we have to sum all the distances
P = d1 + d2 + d3
P = 34 ft + 30 ft + 67 ft = 131 ft

Answer:
the intrinsic growth rate of the population = 0.67 - 0.06 = 0.61 or 61%
Step-by-step explanation:
since populations increase exponentially, the same will happen here
in 5 years the population should be:
P₅ = P₀e°⁶¹ˣ⁵ = 140e°⁶¹ˣ⁵ = 2,956.15 ≈ 2,956
in 10 years the population will be:
P₁₀ = P₀e°⁶¹ˣ¹⁰ = 140e°⁶¹ˣ¹⁰ = 62,420.09 ≈ 62,420
when you are using exponential growth rates, we have to assume that r will always remain constant
