For given functions for zombies and vampires, zombies will reach 50,000 first.
What is a function?
A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and co-domain or range. A function is generally denoted by f(x) where x is the input. The general representation of a function is y = f(x).
There are several types of functions in math. Some important types are:
Injective function or One to one function: When there is mapping for a range for each domain between two sets.
Surjective functions or Onto function: When there is more than one element mapped from domain to range.
Polynomial function: The function which consists of polynomials.
Inverse Functions: The function which can invert another function.
Now,
Initial numbers, 100 Zombies and 100 Vampires.
In function z(t), the zombies increase in population by 1000 per day,
and in function V(t), the vampire population increases by 25% each day,
Therefore, z(t)=100+1000t where t=no, of days and
v(t)=100+25t where t= no. of days
for z(t)=50000
100+1000t=50000
t=49900/1000=49.9≈50days
for v(t)=50000
100+25t=50000
t=49900/25=1996 days
Hence,

What is the formula for the sum of a sequence?.
The formula for the sum of an arithmetic sequence is [tex]S_n[/tex]=[tex]n/2[/tex][2a+(n−1)d], [tex]S_n[/tex] = [tex]n/2[/tex] [2a +( n − 1 )d ], where: n = the number of terms to be added. a = the first term in the sequence. d = the constant value between terms.
In arithmetic, a chain is an enumerated series of gadgets in which repetitions are allowed and order matters. Like a hard and fast, it consists of contributors (additionally referred to as elements, or terms). The quantity of elements (possibly endless) is called the duration of the series.
Unlike a fixed, the same factors can appear a couple of times at distinct positions in a chain, and unlike a fixed, the order does be counted. formally, a chain can be described as a function from herbal numbers (the positions of elements inside the collection) to the factors at each position. The belief of a sequence may be generalized to a listed family, defined as a character from an arbitrary index set.

which expression can be used to find the sum of the polynomials?
The correct expression to solve te sum of polynomials is [(-3x)+(-8x)]+4x+[9+5] (D).
To solve any polynomials problems, it is important for us to take a close look on the orders of each number. For the sum and substraction operation, we need to categorize each number based on its orders.
From the case, we have a problem as:
(9 - 3x²) + (-8x² + 4x + 5)
We can categorize each order:
Order 2 = (-3x²) and (-8x²)
Order 1 = 4x
Order 0 = 9 and 5
Hence, we can solve the problem as:
(9 - 3x²) + (-8x² + 4x + 5)
= [(-3x²) + (-8x²)] + 4x + (9 + 5)
= -11x² + 4x + 14

a total of 516 tickets were sold for the school play. they were either adult tickets or student tickets. there were 66 more student tickets sold than adult tickets. How many adult tickets were sold
In the word problem the number of the adult ticket is 225.
What is word problem?
Word problems are often described verbally as instances where a problem exists and one or more questions are posed, the solutions to which can be found by applying mathematical operations to the numerical information provided in the problem statement. Determining whether two provided statements are equal with respect to a collection of rewritings is known as a word problem in computational mathematics.
Here total number of tickets = 516.
Which is contains adult and students tickets. Then let us take x is number of adult ticket and y is number of student tickets then,
=> x + y = 516 ------> 1
Now there were 66 more student tickets sold than adult tickets then
=> y = x+66 -----> 2
Now put 2 into 1 then
=> x+66+x = 516
=> 2x = 516-66 = 450
=> x = 225.
Now put x = 225 into then
=> y = 225+66 = 291.
Hence the number of adult tickets is 291.

Why are complex fractions called complex?.
Complex fractions are called complex because they contain one or more fractions within the numerator and/or denominator of the fraction. These fractions within the fraction make the fraction more complex or difficult to simplify than a regular fraction, which only has a single numerator and denominator.
The term "complex" in mathematics often refers to something that is composed of multiple parts or layers, and that requires more steps or understanding to work with or solve.
In this case, the presence of one or more fractions within the fraction makes it more complex than a regular fraction, hence the name "complex fraction."
Another reason for the term complex is that the fractions in the numerator and denominator may have different or even the same variables, making it difficult to cancel them or simplify the expression.

Attendance i decreaing at a rate of 0. 5% per year. If there are 1200 people attending now how many will be attending in 4 year?
So, in 4 years, there will be 1176 people attending.
To find out how many people will be attending in 4 years, you need to determine the total decrease in attendance over that time period. The attendance is decreasing at a rate of 0.5% per year, so over 4 years, the decrease in attendance will be 4 years x 0.5% = 2%
To find out how many people will be attending in 4 years, you can then subtract the 2% decrease from the current attendance of 1200 people:
1200 x (1 - 0.02) = 1176 people
So, in 4 years, there will be 1176 people attending.

You must ascertain the overall drop in attendance over that time span in order to calculate the number of attendees in 4 years. If enrollment drops by 0.5% annually, it will drop by 2% over the course of four years (4 years x 0.5%).
Then, from the present attendance of 1200 people, subtract the 2% decline to determine how many attendees there will be in 4 years:
1200 times (1-0.02) ≈ 1176 individuals
Therefore, there will be 1176 attendees in 4 years.

Will the quotient of the division problem shown below be positive or negative?
(-8) ÷ (-4)
Answer: Positive
Hope this helps :)
Step-by-step explanation:
When multiplying or dividing with two negative numbers, the product/quotient will always be positive.
-8/-4 = 2
Answer: Positive
Step-by-step explanation:
Example for multiplication:
Imagine 4 friends that owe you $8 each.
Each friend that pays you back represents their payback as -$8.
-$8 * 4 friends = -$32 that they owe you.
The moment they give it back, you now have +$32. The Debt was taken away.
Example for Division:
Imagine splitting 8 dollars in debt with 4 friends, each friend then has $2 in debt. Each payback means you have +$2.
Another visual way to think of this is with Number Lines.
On a number line, when you multiply by a larger absolute value the numbers get bigger and go farther away from 0. So, taking a negative and multiplying it by a positive makes it MORE negative, as opposed to multiplying it by negative and then it reflects the number line,

After 5 minutes, there are 11 gallons of water in the tub and after 10 minutes, there are 22 gallons in the tub.
Write an equation that relates the number of gallons, g, to the time, t.
Does the relationship represent a linear function? Justify your response.
The equation is y = 2.2x. Yes, it represents a linear function.
What is a linear function?
A linear function is one that has the highest degree of 1 possible. This indicates that there are no variables in a linear function with exponents greater than 1. Such an equation on the graph, forms a straight line.
We are given that
Stopper is applied at t = 0
At t = 5 minutes ; water in tub = 11 gallons
At t = 10 minutes ; water in tub = 22 gallons
We know that a general form of a linear function is y = mx + c.
Where c is the intercept ; m is the Slope ; y and x are dependent and independent variables respectively
Here, the intercept is gallon of water at t = 0 ;
Since, it is not mentioned, therefore it will be taken as 0.
Slope = change in y / change in x
Slope = (22 - 11) / (10 - 5)
Slope = 11 / 5
Slope = 2.2
Therefore, the equation becomes
y = 2.2x + 0
y = 2.2x
Yes, it represents a linear function because the highest degree is 1.
Hence, the equation is y = 2.2x. and it represents a linear function.
