The monthly payment amount a woman has to pay for the car is $462.91.
Here we have to find the monthly payment amount.
The cost of car = $23,800
Down payment = $3,500
Rate(r) = 4.5%
time(t) = 4 years
Periodic interest(i) = 0.045/12
Formula to calculate monthly payment:
A = P i( 1 + i[tex])^{n}[/tex] / ( 1 + i[tex])^{n}[/tex] - 1
Loan amount = 23800 - 3500
= $ 20300
A = 20300 ( 0.045 /12 ( 1 + 0.045/12[tex])^{48}[/tex])/ (1 + 0.045/12[tex])^{48}[/tex] - 1
= 20300× 0.004488 / 0.196814
= 462.91
Therefore the monthly payment is $462.91.

you have a box with a square base and no top. the surface area of the box is 220 ????????????????2. find the maximum volume.
The required maximum volume of the box would be 85184 cube units.
The surface area of a box is the total area of all of the box's faces. For a box with a square base and no top, the surface area is equal to the sum of the areas of the four sides and the bottom.
To find the maximum volume of such a box, we can first find the length of one side of the square base. We can do this by dividing the given surface area by the number of sides of the box.
In this case, the box has 4 sides plus the bottom, so the length of one side is 220 / 5 = 44.
We can now use the length of one side to find the maximum volume of the box. The volume of a box with a square base and no top is equal to the length of one side cubed.
The length of one side is 44, so the maximum volume of the box is :
⇒ 44 × 44 × 44 = 85184.
Therefore, the maximum volume of the box is 85184 cube units.

A 15 square metres sector will have a radius of 8.1 m and a central angle of 26.04 degrees.
What is sector?The region of a disk encompassed by two radii and an arc is called a circular sector, also known as a circle sector or disk sector. The smaller area is referred to as the minor sector, and the larger area as the major sector. A sector is referred to as a component of a circle made up of the circle's arc and its two radii. It is a section of the circle made up of the arc's circumference and the radii of the circle at its ends. A slice of pizza or a pie can be used as an analogy for the form of a circle's sector.

what are the major differences between a population that is experiencing logistic growth and one that is experiencing exponential growth?
If resources are unlimited, population will increase exponentially. A logistic growth happens as those resources are less readily available.
Explain the term logistic growth and exponential growth?Exponential Growth:
The term "exponential growth" describes a population's expansion through time at a pace that is directly proportionate to its size. The population's size is influenced by both the birth and death rates. When there are plenty of resources for everyone in the population, exponential expansion happens. When the number of objects is plotted against time, it yields a J-shaped curve.Logistic Growth:
A population growth known as logistic growth is a group of people whose rate of growth reduces as the number of individuals increases and becomes zero whenever the population reaches its maximum.People in the population compete for resources so when food supply and available space are limited.Thus, there are several key distinctions between populations growing logistically and those growing exponentially.

In investment of $1800 in the stock market are $278 in two years find the simple interest rate
The interest rate is -42.3%, where the negative sign indicates depreciation.
What is the interest rate?The percentage that a lender adds to the amount of money lent to them is called an interest rate.
Given that, the investment of $1800 in the stock market is $278 in two years.
Therefore, the amount depreciated is:
278 - 1800
= -1522
Since 1522 is depreciated in 2 years, the amount depreciated in one year is:
1522/2
= 761
The rate at which the amount depreciated is:
(761/1800)×100%
= 42.3%

Answer: A one out of six chance for the number four to be rolled.
Step-by-step explanation:
Evaluate each general power function at the indicated values.
1.
f(x) = x^n, where n is even
f(1) = ?
f(-1) = ?
2.
g(x) = x^n, where n is odd
g(1) = ?
g(-1) = ?
Step-by-step explanation:
remember, an exponent n just means that the base is multiplied by itself n times.
so, e.g.
a³ = a×a×a = (a×a)×a
a⁶ = a×a×a×a×a×a = (a×a)×(a×a)×(a×a)
as you can see, any even exponent can be written as products of squares.
and any odd (uneven) exponent can be written as product of squares multiplied by one base.
a square of a real number is always positive. therefore, an even exponent of a real number is always positive.
and an odd exponent has the sign of the base (as the result of these multiplications is the product of the squares, that are always positive and one instant of the base, and +×+ = +, +×- = -).
and 1^n = 1
no matter how often I multiply 1 by 1, I get 1 as result.
also : -×- = +
1.
f(x) = x^n, n is even
f(1) = 1^n = (1×1)×(1×1)×...×(1×1) = 1×1×1×...×1 = 1
f(-1) = (-1)^n = (-1×-1)×(-1×-1)×...×(-1×-1) = 1×1×1×...×1 = 1
2.
g(x) = x^n, n is odd
g(1) = (1×1)×(1×1)×...(1×1)×1 = 1×1×1×...×1×1 = 1
g(-1) = (-1×-1)×...×(-1×-1)×-1 = 1×1×...×1×-1 = -1

A coat is marked down by 10% and the customer is given a second discount of 25% what is the sales price
The sales price of the coat is 67.5% of the original price
How to determine the sales price of the coat ?From the question, we have the following parameters that can be used in our computation:
Markdown rate = 10%
Second discount = 25%
The retail price of the coat can be calculated using the following equation
Retail price = original price * (1 - Markdown rate) * (1 - discount)
Substitute the known values in the above equation, so, we have the following representation
Retail price = original price * (1 - 10%) * (1 - 25%)
Evaluate the products
Retail price = original price * 0.675
Rewrite as
Retail price = 67.5% of the original price
Hence, the sales price is 67.5% of the original price

The reasoning is from the following:The formula for simple rate of interest is F = P(1+rt) whereF = future valueP = present valuer = ratet = time
If $10,000 is invested at x percent simple annual interest for n years, the total amount of interest would be F = 10,000n(x/100)
What is simple interest?Simple interest is calculated based on the principle of a loan or the initial deposit into a savings account. Simple interest doesn't compound, so a creditor will only charge interest on the principal sum, and a borrower will never be required to pay interest on interest that has already accrued.
F = P(1+rt), formula for simple rate of interest
Here,
=> Future value is F
=> Present value is P
=> Rate is R
=> Time is t
Substituting x for r
And, n for t
Also, 10,000 in for P
F = 10,000(1+xn)
The formula tells us principal + interest,
F = 10,000(xn)
