The population of the city in 2023 is 1.6 * 10^6.
What is the exponential function?The exponential function is a mathematical function that describes the growth of a quantity as a power of another quantity.
In mathematics, the exponential function is used to model a wide range of phenomena including exponential decay, compounding interest, and population growth.
Using the exponential growth model;
P = Poe^rt
P = population at time t
Po = Initial population
r = Population growth rate
t = time
4Po = Poe^rt
If t = 1
4Po/Po = e^r
4 = e^r
r = ln4
r = 1.4

now consider the situation when no two people get off at the same floor. before the elevator begins to travel, each of them pushes a button for his or her floor. in how many ways can the elevator buttons be lighted?
The number of ways the elevator buttons can be lighted is (m)(m-1)(m-2)...(m-n+1).
What is Permutations?
The mathematical notion of permutation describes the placement of things in a particular order. It is a method of determining how many unique configurations there are for a given set of objects.
If there are n persons in the elevator, and each one presses a button for a floor between 1 and m, what would happen? (inclusive). The number of permutations of m things taken n at a time, indicated as P, determines the number of ways the elevator buttons can be lit if no two individuals hit the same floor button and each person pushes a different floor button (m, n).
[tex]The formula for permutations is: P(m, n) = m! / (m - n)!.Therefore, the number of ways the elevator buttons can be lighted is:P(m, n) = m! / (m - n)! = m! / (m - n)! = m! / (m - n)! = m! / (m - n)! = (m)(m-1)(m-2)...(m-n+1).[/tex]

Find The Length S Of The Circular Arc. (Assume R = 6 And 0 = 126º.) S = O
The required length of the arc of the circle is approximately 13.08 cm.
What is arc?In mathematics, an arc is defined as a portion of the boundary of a circle or a curve. It can also be referred to as an open curve. The boundary of a circle is the perimeter or the distance around a circle, also known as the circumference.
According to question:The length of an arc of a circle is given by the formula:
L = θ * r / 180 * π
Where θ is the central angle in radians, r is the radius, and π is pi.
In your case, the radius of the circle is 6, and the central angle is 126°, so we need to first convert 126° to radians:
θ = 126° * π / 180 = 2.18 radians
Substituting the values in the formula, we get:
L = θ * r / 180 * π = 2.18 * 6 / 180 * π = 2.18 * 6 / π = 13.08 cm
So the length of the arc of the circle with radius 6 and central angle 126° is approximately 13.08 cm.

Suppose you wanted to reach Alpha Centauri (4.4 ly from the Solar system) in 110 years. Pa How fast would you have to go in km/hr? Express your answer in kilometers per hour to two significant figures. v = 4.3x107 km/hr
the speed from kilometers per year to kilometers per hour 4.3x107 km/hr, the distance of 4.4 light years to kilometers.
1. First, convert the distance of 4.4 light years to kilometers.
1 light year = 9.46x1012 km
4.4 light years = 4.1x1013 km
2. Next, divide the distance by the time to calculate the speed:
Speed = Distance/Time
Speed = 4.1x1013 km/110 years
Speed = 3.7x1011 km/year
3. Finally, convert the speed from kilometers per year to kilometers per hour:
1 year = 8760 hours
Speed = 3.7x1011 km/8760 hours

The given equation is [tex]$\frac{4-4-40-1-100-1}{xyz} = -434$[/tex]. To solve this equation, we need to find the value of [tex]$xyz$[/tex]. We can use the distributive property to break up the numerator, yielding [tex]$\frac{(-1)(-100)(-1)}{xyz} = -434$[/tex]. Then, we can multiply both sides by [tex]$xyz$[/tex] to get [tex]$(-1)(-100)(-1)xyz = -434xyz$[/tex] . Since the terms on both sides of the equation are equal, we can simplify to [tex]$(-1)(-1)(-100)xyz = -434xyz$[/tex] . Now, we can factor out the xyz, which yields [tex]$xyz(-1)(-1)(-100) = -434xyz$[/tex]. Since we want to find the value of xyz, we can divide both sides by the common factor of xyz, yielding [tex]$(-1)(-1)(-100) = -434$[/tex] .

if an aircraft is certificated with 275 seats, but only 249 passengers are aboard for that flight segment, how many flight attendants are required? group of answer choices 6 4 7 5
5 flight attendants are required.
The number of flight attendants required on an aircraft is determined by regulatory agencies such as the Federal Aviation Administration (FAA) in the United States and the European Aviation Safety Agency (EASA) in Europe.
The number of flight attendants depends on several factors, including the type of aircraft, the number of passenger seats, the length of the flight, and the number of passenger exits.
The number of flight attendants required can be determined by the following formula:
The minimum number of flight attendants = (N / 50) + 1 where N is the number of passenger seats.
So, for an aircraft with 275 seats and 249 passengers:
(249 / 50) + 1

____ 15. if gasoline costs $1.95 per gallon is its cost per liter? [1 quart = 0.946 liter]
If gasoline costs $1.95 per gallon $0.52 is its cost per liter?
One gallon of gasoline costs $1.95. To find the cost per liter, we need to convert gallons to liters. The conversion factor between gallons and liters is 1 gallon = 3.78541 liters.
So, to convert gallons to liters, we multiply the number of gallons by 3.78541.
In this case, the cost of one gallon of gasoline is $1.95. To find the cost per liter, we need to convert $1.95 from dollars per gallon to dollars per liter.
To do this, we divide $1.95 by the conversion factor between gallons and liters:
$1.95 / 3.78541
= $0.52/liter.
Therefore, the cost of one liter of gasoline is $0.52.

To find the percentage of people who supported the home team, we need to calculate the proportion of people supporting the home team and convert it to a percentage.
The total number of people attending the game is,
2940 + 560 = 3500.
The proportion of people supporting the home team is,
= 2940 / 3500
= 0.84.
To convert this proportion to a percentage, we multiply it by 100:
= 0.84 × 100 = 84%
Thus, 84% of the people attending the basketball game supported the home team.

Jayden went to the grocery store and purchased cans of soup and frozen dinners. Each can of soup has 200 mg of sodium and each frozen dinner has 650 mg of sodium. Jayden purchased a total of 13 cans of soup and frozen dinners which collectively contain 4400 mg of sodium. Write a system of equations that could be used to determine the number of cans of soup purchased and the number of frozen dinners purchased. Define the variables that you use to write the system.
The number of cans are 9 and number of frozen food is 4.
What is a system of equations?A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.
Given that, Jayden bought cans of soup and frozen dinners. Each can of soup has 200 mg of sodium and each frozen dinner has 650 mg of sodium. Jayden purchased a total of 13 cans of soup and frozen dinners which collectively contain 4400 mg of sodium.
Let she bought x cans and y frozen food.
Therefore, establishing the equations,
x + y = 13
y = 13-x...(i)
200x + 650y = 4400...(ii)
Put eq(i) in eq(ii)
200x + 650(13-x) = 4400
200x + 8450 - 650x = 4400
450x = 4050
x = 9
Put x = 9 in eq(I)
y = 13-9
y = 4
Hence, the number of cans are 9 and number of frozen food is 4.

in a convex quadrilateral, the measure of the largest angle is twice the measure of the smallest angle, and the other two angles are both right angles. how many degrees are in the largest angle?
Answer: 90 degrees.
Step-by-step explanation:
Step 1: The smallest angle must be 90/2 = 45 degrees.
Step 2: The largest angle is twice the size of the smallest angle, so it is 90 degrees.
