Hey there!
When we put a number in scientific notation, we want the first number to be at least 1 and less than 10. There must be a digit from 1-9 in the ones place.
With the number 0.000015, we can move the decimal place 5 places to the right and we have 1.5, which is more than one and less than ten.
Because we moved the decimal place 5 places to the right, 1.5 is multiplied by 10 to the power of -5.
The 5 is the number of places the decimal is moved, and the negative sign is because we moved it to the right.
10^(-5) is the same as 0.00001, just for context.
So, 0.000015 meters in scientific notation is 1.5 x 10^(5) meters.
Hope this helps!

Step-by-step explanation:
Given
---x = 0, in 2012
-- x = 5, in 2017
Required
Select all possible equations
Because there is a reduction in the population, as time increases; the rate must be less than 1.
An exponential function is represented as:

Where

rate > 1 in options (a) and (b) i.e. 1.03
This implies that (a) and (b) cannot be true
For option (c), we have:

Set x = 0

Set x = 5

<em>This is true because the calculated values of f(0) and f(5) correspond to the given values</em>
For option (d), we have:

Set x = 0

<em>This is false because the calculated value of f(0) does not correspond to the given value</em>
For option (e), we have:

Set x = 0
undefined
<em>This is false because the f(x) is not undefined at x = 0</em>
For option (f), we have:

Set x = 0

<em>This is false because the calculated value of f(0) does not correspond to the given value</em>
<em>From the computations above, only (c) </em>
<em> is true</em>
