= 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

Given information
Cost of investment=$20000
Selling price=$22000
Profit=Selling price-Cost of investment=22000-20000=2000
Return on investment=profit/cost of investment

Answer:
3
Step-by-step explanation:
Simplify: (-7x2 - 3x) - (4x2 - x) ... -11x2 – 2x ... 3x – 5 + 23x – 9 = 3x + 23x – 5 – 9 = 26x – 14 = 2(13x – 7) Answer: 2(13x – 7). 11 . ... 2x - 3 + 3 = - 9 + 3, (Adding 3 on both sides) 2x = -6 2x/2 = -6/2
