maybe u missplaced it somehow and it also would depend if you trust that person or not. some times that 'friend' can turn out to be fake but i don't mean it about ur friend. for now, u should just ask, there's no harm in that.
Associative an example of this property is 3x4x6=4x3x6
Answer: y(t) = 600(0.921)^t
Step-by-step explanation:
Given:
Percentage yearly reduction = 7.9%
Initial mass m = 600 mg
time in years = t
An exponential function with yearly decay rate to determine the final mass of the substance is given as:
y(t) = m(f)^t
y(t) = final mass in milligram
m = 600
f = final mass fraction = 1 - 0.079 = 0.921
f = 0.921
Therefore, the exponential function is given as;
y(t) = 600(0.921)^t
