Step-by-step explanation:
Write the following Arithmetic Sequence using a Recursive Formula: an = -7 + 3(n – 1)
a1 = 3, an = an-1 – 7
a1 = -7, an = an-1 + 3
a1 = -7, an = an+1 + 3
a1 = 3, an = an+1 – 7
9514 1404 393
Answer:
(b) a[1] = -7, a[n] = a[n-1] + 3
Step-by-step explanation:
Comparing the given formula to the general form for the n-th term of an arithmetic sequence ...
an = a1 +d(n -1)
we see that the first term (a1) is -7, and the common difference (d) is +3.
The recursive version of the sequence definition is ...
a[1] = a1
a[n] = a[n-1] +d
So, the appropriate choice is ...
a[1] = -7, a[n] = a[n-1] +3
If the x-axis is the perpendicular bisector of a segment with an endpoint of (2,3) what are the coordinates of the other endpoint of this segment?
Answer:
(2, -3)
Step-by-step explanation:
The x-axis is the perpendicular bisector of a segment with an endpoint of (2,3).
A perpendicular bisector is a line which is perpendicular to a segment, dividing the segment into two equal parts. The perpendicular bisector passes through the midpoint of the segment.
Since the x axis bisects a segment with an endpoint of (2,3) perpendicularly, hence a point on the x axis is the midpoint of the segment. The midpoint would have the same x coordinate as the endpoint.
Hence, the midpoint is (2, 0).
Let (x, y) be the other endpoint, then:
(2, 0) is the midpoint of the segment joining (2, 3) and (x, y). we find the value of x and y using:
(2 + x) / 2 = 2; and (3 + y) / 2 = 0
2 + x = 4; and 3 + y = 0
x = 4 - 2 ; and y = 0 - 3
x = 2; and y = -3
Hence the other endpoint is at (2, -3)
Because the x-axis is the perpendicular bisector of a segment with an endpoint of (2, 3), we will see that the other endpoint must be at (2, -3).
How to find the other endpoint?First, we know that the x-axis is perpendicular to our segment, so our segment must be a vertical segment. This means that there can't be a variation in the x-values between the endpoints.
So, if one endpoint is (2, 3), then the other must be (2, y).
To find the value of y we use the fact that the x-axis is also a bisector, so it divides the segment in two equal parts, then we must have y = -3
In this way, we can conclude that the other endpoint is (2, -3)

Answer:
2km/hr
Step-by-step explanation:
The formula for calculating speed is expressed as;
Speed = Distance/Time
Given the following;
Distance = 6km
Time = 3hours
Speed = 6km/3hr
Speed = 2km/hr
Hence the speed travelled is 2km/hr

Which of the following is not true of a trapezoid that has been translated 8 units down? A The new trapezoid is in the same orientation as the original trapezoid. B The new trapezoid is the same shape as the original trapezoid. C The new trapezoid is the same size as the original trapezoid. D The y−coordinates of the new trapezoid are the same as the y−coordinates of the original trapezoid.
Answer:
D
Step-by-step explanation:
D. The y-coordinates of the new trapezoid is not the same as the y-coordinates of the original trapezoid.
What is a polygon?In Mathematics, a polygon can be defined as a two-dimensional geometric figure that consists of straight line segments and a finite number of sides. Additionally, some examples of a polygon include the following:
Triangle Quadrilateral Pentagon Hexagon Heptagon Octagon NonagonWhen a trapezoid is translated 8 units down, all of its points will move down 8 units, which means the y-coordinates of each point will decrease by 8.
Therefore, the y-coordinates of the new trapezoid will be different from the y-coordinates of the original trapezoid.
However, A, B, and C are all true statements.
The new trapezoid will have the same orientation (the same angles between its sides), the same shape (the same ratio of the lengths of its sides), and the same size (the same area).
The only difference is that the new trapezoid will be shifted down by 8 units.

Six less than the product of 5 and a number is equal to 2.
Six less than the product of 5 and a number is equal to 2 is represented as 5x - 6 = 2 and x becomes 1.6
Let's break down the statement and solve the equation step by step.
The statement is: "Six less than the product of 5 and a number is equal to 2."
Let's translate this into an equation.
Let "x" be the number we want to find.
The product of 5 and the number "x" is 5x.
"Six less than the product of 5 and a number" is 5x - 6.
Now, we have the equation: 5x - 6 = 2.
To solve for "x," follow these steps:
Step 1: Add 6 to both sides of the equation to isolate the term with "5x."
5x - 6 + 6 = 2 + 6
This simplifies to: 5x = 8.
Step 2: Now, to find the value of "x," divide both sides of the equation by 5.
(5x) / 5 = 8 / 5
This simplifies to: x = 8/5.
So, the value of the number "x" is 8/5, which is equivalent to 1.6.
Therefore, the number is 1.6.

The correct factorization of 12x'2 - 157x - 40: A) (3x -8)(4x - 5) B) (3x - 40)(4x + 1) C) (12x - 1)(x + 40) D) (12x - 5)(x-8)
Answer:
B
Step-by-step explanation:
12x² - 157x - 40
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 12 × - 40 = - 480 and sum = - 157
The factors are + 3 and - 160
Use these factors to split the x- term
12x² + 3x - 160x - 40 ( factor the first/second and third/fourth terms
= 3x(4x + 1) - 40(4x + 1) ← factor out (4x + 1) from each term
= (4x + 1)(3x - 40) ← in factored form → B

Suppose the postal service charges $10.30 per pound on the package shipped to England what is this rate in dollars per ounce
Given:
The postal service charges $10.30 per pound on the package shipped to England.
To find:
The rate in dollars per ounce.
Solution:
We know that,
1 pound = 16 ounce
1 Dollar per pound = [tex]\dfrac{1}{16}[/tex] dollar per ounce.
1 Dollar per pound = 0.0625 dollar per ounce.
We have, the postal service charges $10.30 per pound on the package shipped to England.
Using the above conversion, we get
$10.30 Dollar per pound = [tex]10.30\times 0.0625 [/tex] dollar per ounce
$10.30 Dollar per pound = [tex]0.64375 [/tex] dollar per ounce
Therefore, the required rate is $0.64375 per ounce.

given data
The ratio of girls to boys on the tennis team is 3 to 4.
the combined ratio= 3+4= 7
total boys = 24
Required
the total number of people
Step two:
applying the part to all method, let the total people be x
