For this case we have:
The general formula of the arithmetic sequence is given by:
[tex]a_n = a_1 + (n-1) d\\[/tex]
Where
[tex]a_n[/tex]: Last term
[tex]a_1[/tex]: First term
n: Number of terms
d: Difference
Rewriting according to the given common difference, we have:
[tex]a_n = a_1 + (n-1) (- 4.5)[/tex]
Answer:
[tex]a_n = a_1 + (n-1) (- 4.5)[/tex]
The explicit formula for an arithmetic sequence whose common difference is -4.5 is:
[tex]a_n=a_1-4.5(n-1)[/tex]
Step-by-step explanation:Explicit formula--
Explicit formula is the formula which is used to find the nth term of a sequence.
We know that the explicit formula for an arithmetic sequence is given by:
[tex]a_n=a_1+(n-1)d[/tex]
where d is the common difference of the sequence and [tex]a_1[/tex] is the first term of the sequence.
We have: d= -4.5
Hence, the explicit formula is given by:
[tex]a_n=a_1-4.5(n-1)[/tex]

Hi, there
Question:Ms. Lynch has 21 coins in nickels and dimes. Their total value is $1. 65. How many of each coin does she have?
Explanation:
1.65 x 21
Answer 34.65
Hi!
Ms. Lynch has 21 coins in nickels and dimes. Their total value is $1. 65. How many of each coin does she have?
12 x 0.1 = 1.2
9 x 0.05 = 0.45
1.2 + 0.45 = $1.65
Answer:
She has 12 Dimes and 9 Nickels!

She would put 1000.00 a year into an account starting on the babys 1st birthday
Hello Azzizigilchrist.
The equation of this question would be $1000x
x stands for the amount of years it has been
So if it has been 4 years, 1000 * 4 equals 4000

z+5-4z=8 plz hurry plz
first, rearrange the equation like this
5 + z -4z = 8
Then, simplify the "z"s Then, subtract 5 from both sides
-3z = 3
Then, divide both sides by -3
z = -1
To check
-1 + 5 - 4(-1) = 8
-1 + 5 + 4 = 8 -1 + 9 = 8
8 = 8
An item that is normally sells for $130 is marked down 30%. What is the sale price
To find the sale price of an item that is normally $130 with a 30% markdown, calculate the discount amount ($39) and subtract it from the original price to get a sale price of $91.
The question asks to calculate the sale price of an item after a 30% markdown. To determine the sale price, you have to first calculate the discount amount and then subtract it from the original price of the item. Here's how you do it:
Find the discount amount: original price x discount rate.Subtract the discount amount from the original price to get the sale price.For an item that is normally sold for $130 and is marked down 30%, the sale price can be calculated as follows:
Discount amount: $130 x 0.30 = $39.Sale price: $130 - $39 = $91.An architect notices that the scale on a blueprint he is using has been torn off. However, he sees that a 12.5-ft. wall that has been built is 5 in. long on the blueprint. What is the scale for this blueprint?
Answer:
The scale is : 1 in : 2.5 ft
Step-by-step explanation:
An architect notices that the scale on a blueprint he is using has been torn off.
However, he sees that a 12.5-ft. wall that has been built is 5 in. long on the blueprint.
Let the scale be x
[tex]\frac{5}{12.5} =\frac{1}{x}[/tex]
So, scale = [tex]x=\frac{12.5}{5}[/tex] = 2.5
So, the answer is : 1 in : 2.5 ft
Answer:
The scale is : 1 in : 2.5 ft

Perform the indicated operation . Round the result to the nearest tenth and then to the nearest hundredth . Separate your answers by a comma . -49.256 + 17.197
Final answer:
By adding the two numbers and rounding, we first get -32.1 for the rounding to the nearest tenth and then the same result, -32.1, when rounding to the nearest hundredth.
Explanation:
To perform the indicated operation and round the result first to the nearest tenth and then to the nearest hundredth, we begin by adding the two numbers: -49.256 + 17.197. The sum of these numbers is -32.059. To round to the nearest tenth, we look at the hundredths place, which is 5, so we round up, resulting in -32.1. Next, to round to the nearest hundredth, we consider the thousandths place, which is 9, so we again round up, but since we're already at 9 in the hundredths place, the result remains -32.1.

which is a disadvantage of purchasing and owning a home?
The answer to your question is,
B. Homeowners pay additional property taxes
-Mabel <3
Owning a home can lead to a lack of flexibility, high maintenance costs, and financial risks associated with changes in the housing market.
Explanation:A significant disadvantage of buying and owning a home is the commitment and reduced flexibility compared to renting. When you purchase a home, it becomes a major part of your portfolio, any change in the housing market can directly affect your financial status. Not to mention, if you need to move for a career opportunity or a change in life circumstances, it can be challenging to sell the house, especially if the market conditions are unfavorable.
Furthermore, home ownership often comes with substantial maintenance costs and responsibilities. Unlike renting, where the landlord typically handles maintenance tasks, as a homeowner, these responsibilities and costs are up to you. This can include routine tasks such as gardening and cleaning, to significant unexpected costs like roof replacement or plumbing issues.
Additionally, despite the potential financial return of selling the house in the future for more than you paid for it, this is not guaranteed. The housing market can fluctuate and you may not always make a profit on the resale of your home.

The transformation of triangle abc is an example of what
Final answer:
The transformation of triangle ABC is an example of a linear transformation that preserves lines and parallelism.
Explanation:
The transformation of triangle ABC is an example of a linear transformation.
A linear transformation is a transformation that preserves lines and parallelism. It transforms lines into lines and takes parallel lines to parallel lines.
For example, if triangle ABC is transformed into triangle A'B'C', the corresponding sides of the triangles will be parallel. Additionally, any lines within the triangle will remain lines after the transformation.

theoretical probability and experimental probability are the same true or false?
Answer:
FALSE
Step-by-step explanation:
The statement 'theoretical probability and experimental probability are the same' is generally false. Theoretical probability is what we expect to happen, while experimental probability is based on actual results from experiments. With more trials, these two probabilities tend to get closer, thanks to the Law of Large Numbers.
Explanation:The statement 'theoretical probability and experimental probability are the same' is generally false. Theoretical probability is defined as the number of desired outcomes divided by the number of possible outcomes, assuming that all outcomes are equally likely. It is what we expect to happen in an experiment.On the other hand, experimental probability is the proportion of times an outcome occurs based on actual experimental results. In other words, it is the data observed from repeated trials of an experiment. It's worth noting that with an increasing number of trials, experimental probability tends to get closer to theoretical probability, in accordance with the Law of Large Numbers.Learn more about Probability here:https://brainly.com/question/22962752
