The increase in a person’s body temperature T(t), above 98.6ºF, can be modeled by the function T (t) = StartFraction 4 t Over t squared + 1 EndFraction, where t represents time elapsed. What is the meaning of the horizontal asymptote for this function?
The horizontal asymptote of T(t)=0 means that the temperature will not increase above 98.6F as time elapses.
Given,[tex]T(t)=\frac{4t}{t^2+1}\\[/tex]
where, t represents time elapse it means 't' reaches to infinity
In function [tex]\lim_{n \to \infty} f(n)[/tex], f(n) is called as horizontal asymptote of the function.
then the above equation can be written as
[tex]T(t)=\lim_{t \to \infty}\frac{4t}{t^2+1}\\\\=\lim_{t \to \infty}\frac{4t}{t(t+\frac{1}{t})}\\\\=\lim_{t \to \infty}\frac{4}{(t+\frac{1}{t})}\\\\=\frac{4}{\infty +0}\\\\=0[/tex]
Hence,the horizontal asymptote of T(t) is 0 it means there is no increase in the temperature above 98.6F.

How can the number of times can be calculated?The concept that will be used to solve the question is division operation.
We were given 4.2 x 10^8 which is greater than 2.1 x 10^2
The operation can be expressed as :
4.2 x 10^8 =( n *2.1 x 10^2)
where n = the number of times that 4.2 x 10^8 is greater than 2.1 x 10^2
Then make n the subject of the formular which is
n = 4.2 x 10^8/2.1 x 10^2

What is arithmetic progression?
The difference between two successive words in an arithmetic progression sequence, often known as A.P., is always the same. The common difference is the term for the constant. It is a technique for calculation that has been used for centuries to get precise results for everyday calculations such as measurements, labelling, and other kinds of everyday calculations. The word "arithmos" in Greek, which simply means "numbers," is where the phrase first appeared.What is Geometric progression?
When one term is varied by another by a common ratio, the series is referred to as a geometric progression or sequence. When we multiply the previous term by a constant (which is non-zero), we get the following term in the sequence.The difference of these numbers is 6, so the next two terms of an arithmetic sequence would be 8+6 = 14, and 14+6 = 20.
The ratio of these numbers is 4, so the next two terms of a geometric sequence would be 8×4 = 32, and 32×4 = 128.
Any pair of numbers can be used that is not (14, 20) or (32, 128).
The next two terms could be 0 and 1, or they could be 14 and 32.

Find the measure of each marked angle. Assume the lines are parallel
The value of x is 33
What other external angles are there?
The alternate exterior angle theorem states that when two parallel lines cross, the exterior angles formed on either side of the transversal are equal. The distance between two intersecting lines or surfaces at or around their meeting point is referred to as the angle.
Since (2x - 30°) and (x+3)° are alternate exterior angles, they will be equivalent to one another.
(2x - 30)° = (x+3)°
Separate all similar phrases, then determine the value of x:
(2x - 30)° = (x+3)°
2x - x = 33 + 3
x = 33

6. Rodrigo is attending a 4-year college. As a freshman, he was approved for a 10-year, federal
unsubsidized student loan in the amount of $5,300 at 4.29%. He knows he has the option of
beginning repayment of the loan in 4.5 years. He also knows that during this non-payment
period, interest will accrue at 4.29%. (Round all monthly payment calculations to 2 decimal
places.)
a. How much interest will Rodrigo accrue during the 4.5-year non-payment period?
b. If Rodrigo decides to make no payments during the 4.5 years, the interest will be
capitalized at the end of that period. What will the new principal be when he begins
making loan payments?
How much interest will he pay over the life of the loan?
c. Suppose Rodrigo only paid the interest during his 4 years in school and the 6-month
grace period. What will he now pay in interest over the term of his loan?
Rodrigo will accrue 1023.17 interest during the 4.5-year non-payment period.
Define interest.The simplest way to compute interest is as a percentage of the principal. For instance, if you agreed to borrow $100 from a buddy with 5% interest, the interest you would pay would only be 5% of $100: $100(0.05) = $5. Simple Interest (S.I.) is a way for figuring out how much interest will accrue on a specific principal sum of money at a certain rate of interest. For instance, if someone borrows Rs. 5000 at a rate of 10 p.a. for two years, they will pay S.I. on the borrowed money for those two years.
Given,
For calculating interest:
Interest = Principal ×rate × time
Principal = 5300
Rate = 0.0429
Time = 4.5
Interest = 5300 × 0.0429 × 4.5
Interest = 1023.17
Rodrigo will accrue 1023.17 interest during the 4.5-year non-payment period.

Number of winning tickets =7 and Number of losing tickets = 28. When there are 35 tickets in a bag and the ratio of winning tickets to losing tickets is 1:4
What is ratio?Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorize ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings. For instance, a class has a 12:15 boy-to-girl ratio, whereas the part-to-whole ratio refers to the relationship between a particular group and the entire. For instance, five out of every ten people enjoy reading. As a result, the ratio of the part to the whole is 5: 10, meaning that 5 out of every 10 persons enjoy reading.Given: Total tickets = 35

What is 2 sigma confidence interval?
Step-by-step explanation:
A two sigma confidence interval is created whenever our alternate hypothesis does not equal a value.
For example if
[tex]h_{o} = 0.36[/tex]
and
[tex]h _{a} ≠0.36[/tex]
We used a two sigma confidence interval because we are thinking a portion is either below 0.36 or above 0.36.
When solving these probability for the p value, multiply the inital result by 2 to get the p value
The 2 sigma confidence interval is a principle that states that a result will be considered significant if 95% of the population is two standards deviation from the average value.
What is the 2-sigma confidence interval?The two-sigma confidence level states that 95% of the values obtained in the results from a population should be within2 deviations from the mean. Anything below this acceptable percentage is not considered the 2-sigma confidence level.
If 68% of the score are within 1 standard deviation from the mean, then that will be considered the 1-sigma rule. If 99.7% of the score is 3 standard deviations from the mean then we can refer to that as the 3-sigma confidence interval.

Opera tickets sold for $7.50 on the main floor and $5 in the balcony. The total revenue was $3250, and there
were 100 more main floor tickets sold than balcony tickets. Find the number of tickets sold.
Answer
500 tickets were sold
Step-by-step explanation:
Since 100 main floor tickets were sold, and each cost $7.50, we multiply it by 100 which equals $750, then since revenue was $3250, we do $3250 - $750 = $2500. Now that we got the extra tickets taken out of the way, time to find the rest. First, we add the prices of both tickets together, $7.50 + $5 = $12.50, then divide it by the remaining revenue, $2500 divided by $12.50 = 200 tickets, so 200 of each ticket were sold, + 100 main floor tickets. So now we do 300 main floor tickets + 200 balcony tickets, which is 500 tickets in total. Maybe you didn't read this but that's alright :)
