What is an arithmetic sequence?A series of integers called an arithmetic succession or arithmetic chain of events has a fixed difference between the terms.
Let a₁ be the first term and d be a common difference.
Then the nth term of the arithmetic sequence is given as,
aₙ = a₁ + (n - 1)d
The explicit rule for a sequence and one of the specific terms is given.
fₙ = (3n - 3) + 3
If the value of the nth term is 72. Then the position of the term is given as,
72 = (3n - 3) + 3
72 = 3n - 3 + 3
72 = 3n
n = 72 / 3
n = 24
The value of the nth term is 72. Then the position of the nth term will be 24.

A culture of bacteria has an initial population of 12000 bacteria and doubles every 6 hours. Using the formula P_t = P_0\cdot 2^{\frac{t}{d}}P t =P 0 ⋅2 d t , where P_tP t is the population after t hours, P_0P 0 is the initial population, t is the time in hours and d is the doubling time, what is the population of bacteria in the culture after 17 hours, to the nearest whole number?
Answers
Answer:
85,524 bacteria
Step-by-step explanation:
Given the population of bacteria modelled by the equation where;
[tex]P_t = P_0\cdot 2^{\frac{t}{d}[/tex]
P0 is the initial population
t is the time in hours
d is the doubling time
If the culture of bacteria has an initial population of 12000 bacteria, this means that;
at t = 0, P0 = 12000
substitute into the modelled function
[tex]P_t = P_0\cdot 2^{\frac{t}{d}\\\\P_t = 12000\cdot 2^{\frac{0}{d}\\\\\\P_t =12000\cdot 2^{0}\\\\P_t = 12000[/tex]
If the population doubles every 6 hours
at t = 6, Pt = 24000
[tex]P_t = P_0\cdot 2^{\frac{t}{d}\\\\\\24000 = 12000\cdot 2^{\frac{6}{d}\\\\\\\\24000/12000 = 2^{\frac{6}{d}\\\\\\\\[/tex]
[tex]2 = 2^{\frac{6}{d} }\\1 = 6/d\\d = 6\\[/tex]
Next is to get the population of bacteria in the culture after 17 hours
at t = 17, Pt = ?
[tex]P_t = P_0\cdot 2^{\frac{t}{d}\\\\P_t = 12000\cdot 2^{\frac{17}{6}\\\\\\\\P_t = 12000\cdot 2^{ 2.833 }\\P_t = 12000\cdot 2^{ 2.833 }\\P_t = 12000 * 7.127\\P_t = 85,524.3[/tex]
Hence the population of bacteria in the culture after 17 hours, to the nearest whole number is 85,524 bacteria

How many regular-time hours did Steve work? 2. How many overtime hours did he work last week? 3. What was Steve's regular-time pay last week? 4. What was Steve's gross or total pay last week?
Answers
Answer:1. 40 hours 2).7.3 hours, 3).$480 4).$611.4
Step-by-step explanation:
STEP 1
stating all requirements
regular hour = 40 hours at $12 an hour
overtime = beyond 40 hours at $18 an hour
Step 2--- Solving out
1. Steve worked 40 regular time hours
2. Over time hours =Total 47.3 hours - 40 regular time hours = 7.3 hours
3. Regular time pay = Regular tmes hours x regular time pay rate
= 40 x $12 =$480

An engineer is designing a runway for an airport. Several planes will use the runway and the engineer must design it so that it is long enough for the largest planes to become airborne before the runway ends. If the largest place accelerates at 3.30 m/s^2 and has a takeoff speed of 88.0 m/s then what is the minimum allowed length for the runway?
Answers
Answer:
d=117.33 m
Step-by-step explanation:
Initial velocity of planes, u = 0 (because they are at rest)
Acceleration, a = 3.3 m/s²
Final take off speed, v = 88 m/s
We need to find the minimum allowed length for the runway. Let it is d. d will be the distance. It can be calculated using third equation of motion as follows :
[tex]v^2-u^2=2ad\\\\d=\dfrac{v^2-u^2}{2a}[/tex]
Putting all the values, we get :
[tex]d=\dfrac{88^2-0^2}{2\times 33}\\\\d=117.34\ m[/tex]
Hence, the minimum allowed length for the runway is 117.33 m.

This expression reminds me a lot of Fermat's last theorem x^n+y^n=z^n where n is three(odd). Which is one of many famous diophantine equations such as the well known pythagorean theorem a^2+b^2 = c^2. Where one of the variables should be even, and all are coprime. The parity is odd since it has a remainder and is not evenly divisible. It has been proven that Fermat's last theorem does not have any real solutions because you would need a complex number to cancel out the cubes. You will also see that x^n+y^n=z^n does not have any solutions if n>=3. This cannot be factored either since the numbers are rational.
Give an example of a balance that has a greater integer value than a balance of -$12, but represents a debt of less than $5.
Answers
Answer:
An example of a balance that has a greater integer value than a balance of -$12, but represents a debt of less than $5 is any integer belongs to [-6,-11]
Step-by-step explanation:
Let x be the balance that has a greater integer value than a balance of -$12, but represents a debt of less than $5.
We are given that a balance that has a greater integer value than a balance of -$12
So, x>-12
We are given that balance represents a debt of less than $5.
Debt = -5
So, x< -5
So, -5>x>-12
So, x∈[-6,-11]
Hence an example of a balance that has a greater integer value than a balance of -$12, but represents a debt of less than $5 is any integer belongs to [-6,-11]

The local meteorologist claims that the temperature is going to steadily drop over the next 4 hours.

Explain how you got your answer in two or more complete sentences. plz answer with a real answer will give brainlyest
Answers
Answer:
-7°F/hour.
Step-by-step explanation:
If the total change is -28°F, and we know it took 4 hours, we just have to divide the total change by hours taken to get the change per hour.
So we do the following: [tex]\frac{-28F}{4} = -7F/h[/tex]
So the temperature changes (drops) by -7°F/hour.

What is meant by mathematical operation?Calculating a value using operands and a math operator is referred to as performing a mathematical "operation." The math operator's symbol has predetermined rules that must be applied to the supplied operands or numbers. In mathematics, addition, subtraction, multiplication, division, and modular forms are the five basic operations.
Calculations in mathematics are done using arithmetic operators. A property or variable can be given a value using assignment operators. Text, dates, systems, times, and numeric assignment operators are all possible.
Given: Her annual sales commission is 8% of her base monthly salary, which is $1,750. Ming made $478,500 in travel sales last year.
From the given information, we get
$21,000 base salary = $1750 × 12 months.
478,500 × 0.08 = 38,280 commissions.
simplifying the above equation, we get
21,000 + 38,280 = 59280
Therefore, Ming earn, including commission, last year exists 59280.

y=-3x+3
Step-by-step explanation:
The equation you want to use is y=mx+b. First you want to find m, the slope, but since the slope of 3 is given in all of the answers, you just want to determine if the line is negative or positive. This line is going negative because it approaches the x axis, and crosses it in the negative direction. Now we know the slope is -3x all that's left to do is to find the y intercept represented in the equation y=mx+b as +b. The point where the line crosses the y axis is positive 3, so the final equation is y=-3x+3.

The table shows what time the sunrise and

on the data, what is the total number of
minutes of daylight recorded across these
dates?
Answers
Answer:
There are 2,802 minutes of daylight recorded across these dates.
Step-by-step explanation:
Elapsed Time
Elapsed time is the amount of time that passes from the start of an event to its finish.
We have to recall 1 hour has 60 minutes. Another useful fact is that from a specific time AM to the same time PM there are 12 hours or 720 minutes.
Let's find the minutes of daylight recorded day by day.
Oct, 4th:
From 7:26 am to 7:26 pm there are 720 minutes. Since the sunset time is 13 minutes less, the minutes of daylight are 720 - 13 = 707 minutes.
Oct, 6th:
From 7:27 am to 7:27 pm there are 720 minutes. Since the sunset time is 18 minutes less, the minutes of daylight are 720 - 18 = 702 minutes.
Oct, 8th:
From 7:28 am to 7:28 pm there are 720 minutes. Since the sunset time is 21 minutes less, the minutes of daylight are 720 - 21 = 699 minutes.
Oct, 10th:
From 7:30 am to 7:30 pm there are 720 minutes. Since the sunset time is 26 minutes less, the minutes of daylight are 720 - 26 = 694 minutes.
The total minutes of daylight is 707 + 702 + 699 + 694 = 2,802 minutes
There are 2,802 minutes of daylight recorded across these dates.
