In 2000, 7689 weekly papers = 94% of number of weekly papers in 1960
Let weekly papers in 1960 be x.
7689 = 94% of x
7689 = (94/100)*x
7689 * 100/94 = x
8179.787 ≈ x
x ≈ 8179.787
Number of weekly newspapers in 1960 rounded to the nearest whole number = 8180

Answer:
To get the population of the bacteria at a time t, we just plug in the given value of t
so in this case, we will put 5 in the place of t
f(t) =
f(5) =
we know that the value of e is about 2.7. So the population of the bacteria after 5 hours will be 2.7 to the power 5
which will be equal to:
<u>b) 148.413</u>
<em>note: using 2.7 in the calculation will give slightly different answer since it is an estimated value, i suggest using 'e' in the actual calculation</em>
