Answer:
3w+7
Step-by-step explanation:
Let's simplify step-by-step.
8v+w+7−8v+2w
=8v+w+7+−8v+2w
Combine Like Terms:
=8v+w+7+−8v+2w
=(8v+−8v)+(w+2w)+(7)
=3w+7
Answer:
a) 16.82 mg
b) 24 days
Step-by-step explanation:
Formula for exponential growth is given as:

Where A is the final population
is the initial population
b is the growth factor
c is the time taken for the growth 'b'
t is the amount of time
Here, We are given the following:
= 5 mg
b = 2 (Given because it doubles)
c = 4 days
a) A = ?
Using the formula:

b) Given
A = 320 mg
t = ?
Using the above formula again:

So, the answers are:
a) 16.82 mg
b) 24 days
