Answer the following prompt using the continuous growth formula A=Pe^rt
You have received a report of a mysterious illness that seems to turn the infected humans into mindless zombies has broken out in a major American city. Since the hungry zombies prey upon innocent people, the outbreak grows continuously at a rate of 12% per day. The outbreak begins with 8 people.
1. Write the formula that matches this scenario.
2. How many zombies will there be after 5 days?
3. How many days will it take for the zombie population to reach 3,700,00 (about the population of Los Angeles, CA)?
The solution to the questions are
The formula of the scenario is A = 8 * e^0.12tThe number of zombies after 5 days is 15The number of days is 39How to determine the formula?The general formula is given as
A = Pe^rt
In this case, we have
P = Initial number of people
r = rate
t = time
From the question, we have
P = 8
r = 12% = 0.12
So, we have
A = 8 * e^0.12t
The number of zombies after 5 daysThis means that t = 5
So, we have
A = 8 * e^(0.12 * 5)
Evaluate
A = 15
The number of days to reach 3,700,00This means that A = 3,700,00
So, we have
8 * e^0.12t = 3,700,00
Divide by 8
e^0.12t = 46250
Take the logarithm of both sides
0.12t = log(46250)
This gives
0.12t = 4.7
Divide
t = 39

a circle with a radius of 9.7 inches?
Use 3.14 for
pi.
Enter your answer as a decimal in the box.
The circumference of circle with radius 9.7inch is 60.916 inch.
What is circumference of circle ?The perimeter of a circle is known as its circumference. It is the length of the circle's whole perimeter. The diameter of a circle and the constant are multiplied to get the circumference of the circle. This measurement of a circle's circumference is necessary for someone to cross a circular park or for a circle-shaped table to have a border. The units of the circumference are the same as the units of length and it is a linear value.
A circle is a closed round object whose border points are all equally spaced apart from the center, which is a fixed point.
Given that :the circle with a radius of 9.7 inches
Circumference of a circle is [tex]2\pi r[/tex]
2 ×3.14×9.7 = 60.916
The circumference of circle with radius 9.7inch is 60.916 inch.

In a particular college class, 60% of the students are female. Of the female students, 75% have long hair. One student is picked randomly in the class. What is the probability that it is a female with long.
The probability of selecting a female student with long hair is 45%
Let there be a total of 100 students in the class
Since 60% of the students are female, therefore out of 100 students 60 will be female students
Now, out of these 60 students, 75% have long hair, As a result, = 75% of 60 = 45 female students will have long hair
Probability of selecting female student with long hair = Number of female students with long hair/ Total number of students in the class
= 45/100
So, there is a 0.45 or 45% chance that a female student with long hair is selected

Find the average rate of change:
The table has an average rate of change of 3
How to determine the average rate of change?The table represents the given parameter
From the table, we have the following interval is given as
[3, 7]
This can be rewritten as
x = 3 to x = 7
From the attached table, we have
f(3) = 7
f(7) = 19
The average rate of change of the function is then calculated as
Rate = [f(b) - f(a)]/[b - a]
This gives
Rate = [19 - 7]/[7 - 3]
Evaluate
Rate = 3
Hence, the average rate of change is 3

a ball dropped vertically, falls d t seconds.
d is directly proportional to the sqaure of t.
the ball drop 80 meters in the 4 seconds
how far does the ball drop in the next 8 seconds
If the ball drops 80 meters in the 4 seconds, the time it takes the ball to drop in the next 8 seconds is; 720 meters
How to utilize constant of proportionality?
We are told that a ball dropped vertically falls a distance of d in t seconds and that d is directly proportional to the square of t. Thus;
D ∝ t²
Thus;
D = kt²
where d is the constant of proportionality.
We are given that D = 80 m when t = 4 seconds and as such we have;
80 = k*4²
k = 80/16
k = 5
Therefore, the equation of motion is;
D = 5t²
When t = 8 + 4 = 12 seconds, we have;
D = 5 * 12²
D = 5 * 144
D = 720 m
Therefore, the distance the ball drops in the next 8 seconds
= 720 - 80
= 640 m.

The slope of g(x) is [tex]\frac{-2}{5}[/tex] times the slope of f(x)
The x-intercept of f(x) is 8 more than the y-intercept of g(x)
As x approaches -∞, f(x) approaches ∞ and g(x) approaches -∞
Given,
f(x) = 10-5x
g(x) = -6+2x
The slope of f(x) = -5
The slope of g(x) = 2
Hence the slope of g(x) is [tex]\frac{-2}{5}[/tex] times slope of f(x)
For x-intercept assign zero value to f(x). Thus,
10-5x = 0
=> x = 2
So intercept of f(x) = 2
y-intercept of g(x) = -6
Hence x-intercept of f(x) is 8 more than y-intercept of g(x)
As x approaches -∞, f(x) = 10-(5 times (-∞)) = ∞
As x approaches -∞, g(x) = -6 + 2x = -6 + 2(-∞) = -∞
