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.
I think the answer is in Slader ( aka a app) it usually has answers to go math
Answer: B
Step-by-step explanation:
They've given you two functions f(x) = x^2 + 1 and g(x) = 3x +1 And they are you to find 2 * f(4) then g(x) is not needed so input in 4 for the function f(x) and multiply the output by 2.
F(4) = 4^2 + 1
F(4) = 16 +1
f(4) = 17
17 * 2 = 34

Answer:
A. Kyleigh earned more money per hour.
