El primer término en una secuencia es 5 y el quinto término es 17. ¿Cuál es la diferencia común
The common difference of this Sequence is 12.
In mathematics, a sequence refers to an ordered list of numbers. When working with sequences, there are various concepts and formulas that are used to calculate different aspects of the sequence. One such concept is the common difference. Let's explore what the common difference is and how to calculate it.
What is the common difference?
The common difference in a sequence refers to the difference between any two consecutive terms in the sequence. For example, in the sequence 2, 4, 6, 8, 10, the common difference is 2. We get this value by subtracting the second term (4) from the first term (2) and so on.
How to find the common difference of a sequence?
To find the common difference of a sequence, you need to know at least two terms of the sequence. You can then subtract one term from the other to calculate the common difference.
Let's apply this to the given sequence, which has a first term of 5 and a fifth term of 17. To find the common difference, we can subtract the first term from the fifth term as follows:
17 - 5 = 12
Therefore, the common difference of this sequence is 12.

2x²-2x=12
quadratic equation
You can solve with many ways but I'll do this one instead. Move 12 to the left side and change from positive to negative.
[tex]2x^2-2x-12=0\\[/tex]
Then divide by 2 whole equation.
[tex]\frac{2x^2-2x-12}{2}=\frac{0}{2}[/tex]
Simplify, as we get [tex]x^2-x-6=0[/tex]
We can either use Quadratic Formula or Factoring the Polynomials. It depends but since the polynomial aren't that hard to factor because it doesn't have that many numbers in value. So using factoring will be faster.
From [tex]x^2-x-6=0[/tex] we can factor as -
[tex](x-3)(x+2)=0\\x-3 =0, x+2=0\\x=3, x=-2\\(x=3,-2)#[/tex]
Thus, the value of x is 3 or -2. So x = 3, -2 is the answer.
Note that we can also use Quadratic Formula to solve the equation, however that will take longer than factoring then solve the equation.

-(3z)2
Answer:
-9x²
Step-by-step explanation:
-(3x)²
In PEMDAS, we solve the exponent first then multiply.
-(3x)²
-(9x²)
-9x²
Best of Luck!
Uisng the PEMDAS method of simplifying arithmetic expressions, the expression would be 9z²
Given the expression :
-(3z)²This can be written as :
-3z × - 3z
Negative values will cancel out,
= 9z²
Therefore, the simplified form of the expression would be 9z²

Answer:
(3x + 2)(x-4)
Step-by-step explanation:
3x² - 10x - 8 = 0
(splitting the middle term)
3x² -12x + 2x -8 = 0
3x(x-4) + 2(x-4) = 0
(3x + 2)(x-4) = 0
(3x + 2)(x-4) is the correct answer (option a)

Both answers are correct
Step-by-step explanation:
both y = 1 - 3/2x and y = 1 + -3/2x are correct answers, it is just that y= 1 - 3/2x is the simpler version. Adding a negative number is the same as subtracting a positive.
Given sin(30 degrees) =1/2 and cos (30 degrees) = square root of 3/2 use trigonometry identities to find the value of cot(30 degrees)
1/2
Square root of 3/3
Square root of 3/2
Square root of 3
Answer: D)[tex]\sqrt{3}[/tex]
Step-by-step explanation:
cot(θ) = cos(θ) ÷ sin(θ)
cot(30) = [tex]\frac{\sqrt{3} }{2}[/tex] ÷ [tex]\frac{1}{2}[/tex]
cot(30) = [tex]\sqrt{3}[/tex]
The value of cot30 is √3 if sin30 = 1/2 and cos30 = √3/2 option (D) is correct.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have:
sin30 = 1/2
cos30 = √3/2
As we know,
cotA = cosA/sinA
A = 30 degrees
cot30 = cos30/sin30
cot30 = (√3/2)/(1/2)
cot30 = √3
Thus, the value of cot30 is √3 if sin30 = 1/2 and cos30 = √3/2 option (D) is correct.

$1,850
Answer:
x=$1850
Step-by-step explanation:

Last years discount is 20%
We need to find the original price if the computer now costs $1480.
ATQ,
[tex]x-20\%\ \text{of x}=1480\\\\x-\dfrac{20x}{100}=1480\\\\x-\dfrac{x}{5}=1480\\\\\dfrac{4x}{5}=1480\\\\x=\dfrac{1480\times5}{4}\\\\x=\$1850[/tex]
So, the original cost of the computer model is $1850.

Mrs.Manning is making cookies for the bake sale. She jas 3/4 cup of flour and needs 1/3 cup of flour for her chocolate chip cookies. What fraction of the flour Mrs.Manning has will be used for her chocolate chip cookies?
Answer:
The fraction of the flour Mrs. Mannng will use for her chocolate chip cookies is 4/9
Step-by-step explanation:
Fraction of Portion
Suppose we have a number n and another number m such as m>n. The portion or fraction of size n of m is given by the quotient n/m.
For example, 3 pieces of cake out of a total of 6 make them a fraction of 3/6 = 1/2 of the whole cake, i.e. half of the total available.
Mrs. Manning needs 1/3 cup of flour to make cookies for the bake sale. She actually has 3/4 cups of flour. Calculate the fraction of needed against the available flour:
[tex]\displaystyle \frac{\frac{1}{3}}{\frac{3}{4}}[/tex]
The division can be easier performed by multiplying by the reciprocal of the denominator:
[tex]\displaystyle \frac{1}{3}\cdot \frac{4}{3}=\frac{1*4}{3*3}[/tex]
[tex]\displaystyle =\frac{4}{9}[/tex]
The fraction of the flour Mrs. Mannng will use for her chocolate chip cookies is 4/9

i wish this is the ans ur looking for.......Ron has 198 feet Of fencing to make a rectangular garden in his backyard. He wants the length to be 19 feet more than the width. Find the width?
Answer:
68.5
Step-by-step explanation:
u do 198 divided by 4 then add 19 to the awnser that u got
Answer:
width = 40 feet
Step-by-step explanation:
If w = width, then l = 19 + w
l = 19 + w
2l + 2w = 198
"Substitute 19 + w as l in the second equation"
2(19 + w) + 2w = 198,
38 + 2w + 2w = 198,
38 + 4w = 198,
4w = 198 - 38 = 160,
w = 160/4 = 40 feet
=> Solution: width = 40 feet
Suppose that 11 inches of wire costs 44 cents. At the same rate, how many inches of wire can be bought for 16 cents?
Answer:
4 inches
Step-by-step explanation:
of 11 inches of wire costs 44 cents, then 1 inch of wire costs 4 cents because 44 cents ÷ 11 inches = 4 cents per inch. (44 ÷ 11 = 4)
So, if 1 inch is 4 cents, 16 cents is 4 inches because 16 ÷ 4 = 4
