3 * N = 1
The multiplicative inverse is just the reciprocal of the number. The reciprocal is just " flipping " the number. So the reciprocal of 3 (or 3/1) is 1/3. And any time u multiply a number by its multiplicative inverse (reciprocal), the result is 1
3 * 1/3 = 3/3 = 1.....so N is ur multiplicative inverse

Select true statements from the given options
(a)
= days the bacteria reaches 30000
We have:

In this case:
and 
So, we have:


Using a calculator, we have:

So:

The above equation is false.
(a) is not true
(b) The graph shows that 
We have:

Let t = 3
So;

From the graph, 
So:


Take natural logarithm of both sides

This gives:

(b) is true
(c)
is the logarithm form of 
We have:

Take natural logarithm of both sides

This gives:


(c) is false
(d)
and 
From the graph, we have:
--- rough readings
This implies that:
is true
Because 
Take natural logarithm of both sides

Rewrite as:

We have:

Take natural logarithm of both sides



Substitute
in 

(d) is true
(e) The graph shows that 
We have:

Let t = 2.3
So;

From the graph,
---- rough readings
So:


Take natural logarithm of both sides

This gives:

(e) is true
