Given:
The initial population = 750,000
23% of the population becomes a zombie everyday.
To find:
The function that represents p, the number of unaffected people after x days.
Solution:
The general exponential decay function is:
...(i)
Where, is the initial population, r is the rate of decay and x is the time period.
We know that,
The initial number of unaffected people = 750,000
The unaffected people decreasing by 23% . The decimal form of 23% is 0.23.
Putting in (i), we get
Therefore, the required function is , where p is the number of unaffected people after x days.
Answer:
<u>4 miles per hour</u>

Answer:
One-sixth x + 47
1 and two-thirds x + 35 minus 1 and one-half x + 12
1 and one-third x + 35 minus 1 and one-half x minus 12
Step-by-step explanation:
The original expression in this problem is
We start by applying the distributive property and multiplying each factor outside the brackets by each factor inside:
So we get:
Now we can rewrite this using mixed fractions:
(1)
Which can be also written as
(2)
And finally, by solving it, we find
(3)
So the three correct options are
One-sixth x + 47
1 and two-thirds x + 35 minus 1 and one-half x + 12
1 and one-third x + 35 minus 1 and one-half x minus 12
The answer to the question is a
