Arithmetic sequence is described by the formula aₙ=a₁+(n-1)d.
Arithmetic sequence or Arithmetic progression is a series of numbers where the difference between each number and the number preceding is equal.
Arithmetic sequence is described by the formula aₙ=a₁+(n-1)d.
where aₙ is the n-th term of the sequence
a₁ is the first term of the sequence , n is the number of terms in the sequence and d is the common difference.
The terms of the arithmetic sequence are of first term a and common difference d are a , (a + d), (a + 2d) , (a + 3d)....

How can a number be a power of 10
Answer:
An exponent is often referred to as a power of 10, for instance, [tex]\sf 6\boxed{^7}[/tex], as the exponent is highlighted. A number can only become a power of 10 under certain circumstances in an expression, on the other hand, you have exponents alone in expressions like "45² + x", the exponent was assigned to a number and that means that we multiply that number by itself that number of times. Logically speaking, it's impossible for a number alone to be a power of 10 or to become one out of the blue, a power of 10 is assigned into an expression and before a whole number before you start working on it, which is the equation.

The point J(5,3) is rotated 90° counterclockwise around the origin. What are the coordinates of the resulting point, J^?
If the point J (5,3) is rotated 90° counterclockwise around the origin, then the coordinates of the resulting point J' will be (-3, 5).
As per the question statement, a point J (5,3) is rotated 90° counterclockwise around the origin.
We are required to determine the coordinates of the resulting point J'.
To solve this question, we need to follow a rule of cartesian coordinate geometry which is, "If a point (x, y) is rotated 90° counterclockwise around the origin, then the coordinates of the new point lie on (y, -x).
Here, Coordinates of the original point (J) are (5, 3), i.e.,
(x = 5) and (y = 3).
Therefore, Coordinates of the resulting point (J') after J (5,3) is rotated 90° counterclockwise around the origin will be:
[x' = (y) = 5] and [y' = (-x) = (-3)], or, (-3, 5).
Coordinates: These are a pair of numbers that describe the exact position of a point on a coordinate plane, by using the horizontal and vertical distances from the two reference axes.To learn more about Cartesian Coordinates, click on the link below.

550 yd
What is the total area of the land?
O 365 yd²
O 730 yd²
O 49,500 yd²
O99,000 yd²
The total area of the land that the developer is considering to buy is 49,500 yards².
We are given a triangular plot of land having the dimensions as:
Base = b = 550 yards
Height = h = 180 yards.
We need to find the area occupied by the triangular plot.
Area of a triangle refers to the space occupied by the shape or object.
Area = 1 / 2 × b × h
Substituting the values in the formula, we get that:
Area = 1 / 2 × 550 yards × 180 yards
Area = 550 yards × 90 yards
Area = 49,500 yards²
Therefore, we get that, the total area of the land that the developer is considering to buy is 49,500 yards².

Find the area of the shaded region. (help needed asap. thank u)
The area of shaded region is calculated as: 112.5 cm².
How to Find the Area of the Shaded Region?The area of the shaded region in the diagram above is:
Area of shaded region = area of rectangle - area of triangle = (length)(width) - 1/2(base)(height).
Given the following:
Length of rectangle = 20 cm
Width of the rectangle = 9 cm
Base of triangle = 20 - 3 - 2 = 15 cm
Height of triangle = 9 cm
Plug in the values into the equation, area = (length)(width) - 1/2(base)(height):
Area of shaded region = (20)(9) - 1/2(15)(9)
Area of shaded region = 180 - 67.5

Marley worked 16 hours more than Herold last month. If Marley worked 7 hours for every 2 hours that Herold worked, how many hours did they each work?
Total number of hours both worked last month is; 28.8 hours
How to solve Algebra Word Problems?Let the number of hours that Herold worked last month be x. Thus, number of hours that Marley worked = 16 + x
Now, we are told that Marley worked 7 hours for every 2 hours that Herold worked. Thus;
(16 + x)/x = 7/2
Cross multiply to get;
2(16 + x) = 7x
32 + 2x = 7x
7x - 2x = 32
x = 32/5
x = 6.4 hours
Thus, total hours Marley worked = 16 + 6.4 = 22.4 hours

A pump is being used to fill a 1400-gallon tank. After the pump has run for 2 minutes the tank contains 110 gallons of oil. After 5 minutes the tank contains 200 gallons of oil. Assume the pump fills oil at a constant rate.
(a) Write a linear model that describes the gallons of oil (G) in the tank in terms of the time (t) since the pump was started.
(b) How much oil is in the tank after the pump has been running for 13 minutes?
(c) At what time, will there be 890 gallons of oil in the tank?
(d) What is the t-intercept for this equation? What does it represent in terms of the situation?
Answer:
See below
Step-by-step explanation:
From 2 minutes to 5 minutes the pump puts in (200-110) = 90 gallons ...in 3 minutes....so the rate of the pump is 30 gal / min
at two minutes the pump has put in 30 x 2 = 60 gallons......so there was 50 gallons in the tank to start ( 50 + 60 = 110)
the equation becomes :
G = 50 + 30 t
where t = minutes
and 50 is the initial volume in the tank
For 13 minutes G = 50 + 30 (13) = 440 gallons
For 890 gallons 890 = 50 + 30 t
840 = 30 t
t = 28 minutes
t intercept occurs when G = 0
0 = 50 + 30 t
t = - 5/3 minute <====this is the amount of time before measurements were taken.....or the time for the pump put in 50 gallons before the start
Tyler has a shoe box in the shape of a right rectangular prism. He is filling the box with cubes that are each 1 cubic inch in order to find the volume of the box. He finds that 48 cubes completely fill the bottom of the box and that he can put 2 more layers of cubes in the box. What is the volume of the box in cubic inches?
The volume of Tyler's shoe box is 144 cubic inch
From the question, we are to calculate the volume of the shoe box.
From the given information, we have that
Tyler is filling the shoe box with cubes that are each 1 cubic inch.
and
He found out that 48 of the 1 cubic inch cube completely fills the bottom of the box
Also,
He observed that he can put 2 more layers of cubes in the box.
Thus,
The number of 1 cubic inch cube that would completely fill the box is
48 + (2×48)
= 48 + 96
= 144 cubes
Since the cubes are 1 cubic inch each,
Then,
The volume of the shoe box = 144 × 1 cubic inch
Volume of the shoe box = 144 cubic inch
Hence, the volume of Tyler's shoe box is 144 cubic inch

b) determine the average rate of change between the indicated points on the graph.
The net change between the indicated points is -1 and the average net change is - 0 . 75 .
The difference between the two f(x) values is the net change.
The ratio between the net change and the change between the two input values is used to calculate average net change or average rate of change. The average rate of change can be calculated using the same two points and the formula: f(b)-f(a) / b-a .
The two given points on the graph are (1,4) and (5,1)
The net change is given by the change in the y -coordinates of the graph .
Δy = y₂ - y₁
Here y₂ = 1
and y₁ = 4
Therefore Δy = y₂ - y₁ or, Δy = 1 - 4 = - 3
Hence the net change is -3 units.
Now the average net change is calculate by the change in y divided by the change in x.
average net change = Δy ÷ Δ x

Which are correct representations of the inequality?
We start with the inequality:
-3(2x - 5) < 5*(2 - x)
First, we need to solve this for x, expanding both sides we get:
-6x + 15 < 10 - 5x
Now we move the terms with x to the right side and the terms without to the left side.
15 - 10 < 6x - 5x
5 < x

The suggested answers to the absolute value problem l x - 13 l = 7.
Except for 0, the absolute value is represented by a positive integer. In a variety of mathematical and physical situations, the notions of magnitude, distance, and norm are intimately related to the concept of absolute value.
In order to do this on a budget, find a number N that:
N-10=-(N + 4)
When we isolate N, we obtain:
2N= 10-4= 6
N= 6/2= 3
Following that, N-10= 3-10=-13, and N + 4= 3 + 4= 7.
