9 - 18
5 - 10
1 - 2
Work —
First line:
y = 2 (9)
y = 18
Second line:
10 = 2x
5 = x
Third line:
y = 2 (1)
y = 2
<span>first you set up a proportion 18 over ? = 60 over 100 then cross multiply. 18*100=1800 then divide that by 60 and you get 30 :)</span>
Answer:
93
Step-by-step explanation:
15%=.15
.15 times 620 equals 93
The half-life of the given exponential function is of 346.57 years.
<h3>What is the half-life of an exponential function?</h3>
It is the value of t when A(t) = 0.5A(0).
In this problem, the equation is:
.
In which t is measured in years.
Hence the half-life is found as follows:





t = 346.57 years.
