[tex]a_n = 4+ (n-1)(-7)[/tex] is the explicit formula for the sequence | a₁ = 4
| an = an-1 - 7
We have given [tex]a_1 = 4[/tex]
If [tex]a_n = a_{n-1} - 7[/tex]
Then, [tex]a_2 = a_{(2-1)} - 7[/tex]
⇒ [tex]a_2 = a_1 - 7[/tex]
⇒ [tex]a_2 = 4 - 7[/tex]
⇒ [tex]a_2 = -3[/tex]
Now, common difference (d) = [tex]a_2 - a_1[/tex] = -3 - 4 = -7
The explicit formula for arithmetic sequence is expressed as
[tex]a_n = a+ (n-1)d[/tex] Where a is the 1st term, [tex]a_n[/tex] is the nth term and d is the common difference.
With given information explicit formula:
[tex]a_n = 4+ (n-1)(-7)[/tex]
What is an explicit formula?Without expressing the other terms of the sequence, explicit formulas are always utilized to represent any term of the sequence. The word "explicit" means something that may be found directly without having to know the other phrases in the sequence.
A single formula, known as the explicit formula, can be used to describe each term in a series in an individual way. Without knowing the prior term in the series, the explicit formula makes it simple to locate any term. The explicit formulas for various sequences are provided here:
An = a + (n - 1) d, where a is the first term and d is the common difference, an is the arithmetic sequence.

Third term:
11 = preceding term + 10
That is, 1 + 10 = 11: That is the third term.
As follows:
Fourth and fifth term:
6, 6 = same number repeat for two times.
Sixth term:
6 + 10 = 16
Seventh and eighth term:
11, 11 = same number repeat.
Ninth term:
11 + 10 = 21
Tenth term is given: 16

Do you think it would be better to use breaking apart in the distributive property or compensation to find the product of five times 328? explain why and show how to find the product.
Yes it would be better to use breaking apart in the distributive property or compensation to find the product of 5 x 328 .
what is distributive property?
This property states that multiplying the total of two or more addends by a number will produce the same outcome as multiplying each addend by the number separately and then adding or substracting the results together .like in subtraction A(B-C)= AB-AC
In other words, an equation of the type A (B+C) can be solved as A (B+C) AB+AC in accordance with the distributive property.
This characteristic also holds for subtraction.
5 x 328
= 5(300+28)
= 5 x 300 + 5 x 28
= 1500 + 140
= 1640

Which of the following describes a situation in which the total distance a baseball player travels is zero meters from his starting point? (5 points)
Situation (B) best describes how a baseball player travels a total distance of zero meters from his starting point, that is, the player runs 3 meters forward and then 3 meters in the opposite direction.
What is the distance?Distance is a numerical or quantifiable measurement of the distance between two objects or points. The distance can refer to a physical length or an estimate based on other criteria in physics or everyday usage (e.g. "two counties over"). Because spatial thinking is a rich source of conceptual metaphors in human thought, the term is also frequently used figuratively to mean a measurement of the amount of difference between two common pieces (such as statistical distance between probability distributions or edit distance between text strings) or a degree of detachment (as exemplified by the distance between people in a social network). The concept of a metric space is used in mathematics to formalize most such notions of distance, both physical and metaphorical.According to the options:
Options (A), (C), and (D) is wrong as there the basketball travels some sought distance from the starting point. It is only in option (B) in which the total distance of the baseball player comes to 0 as he runs 3 meters forward and then runs 3 meters in the opposite direction.Therefore, situation (B) best describes that the total distance a baseball player travels is zero meters from his starting point that is, the player runs 3 meters forward and then runs 3 meters in the opposite direction.

Diana usually drives at an average rate of 30 mph. If Diana drives at an average rate of x mph, how long will it take her to get to Tony's house?
Diana drives for two hours at a speed of 30 mph, covering a total distance of 60 miles to get to Tony's house.
What exactly is average speed?Average speed is described as the ratio of a body's total distance traveled to the total time required to reach its destination.The total distance covered by the element in a given time interval is the average speed. A scalar quantity is average speed. It is depicted by magnitude and lacks direction.Diana drives for two hours at a speed of 30 miles per hour.
To calculate the distance she will travel
Average speed = total distance / total time
Total time = two hours and the average speed = 30 mph
30 mph = total distance / two hours
Total distance = 30 × 2
Total distance = 60 miles
Therefore, Diana drives for 2 hours at a speed of 30 mph, so the total distance traveled is 60 miles to get to Tony's house.

A town's population is 42,975 . About 125 people move out of the town each month. Each month, 175 people on average move into town. A nearby town has a population of 45,225. It has no one moving in and an average of 175 people moving away every month. In about how many months will the populations of the towns be equal? Write an equation to model the situation. Then solve the equation and answer the question.
The number of months when they will be equal is 45 months.
How to calculate the equation?The equation for the first town will be:
= 42975 + 125x
The equation for the second town will be:
= 45225 + 175x
The number of months when the populations of the towns will be equal will be:
42975 - 125x = 45225 - 175x
- 125x + 175x = 45225 - 42975
50x = 2250
x = 2250 / 50
