First Five Terms are:
The Sequence is (highlight one): Arithmetic or Geometric
Answer:
Arithmetic
Step-by-step explanation:
Since the common difference remains the same between terms, its arithmetic!
The first five terms of the given AP is 8, 20, 32, 44 ,56.
What is a sequence ?A sequence is a list of numbers written in form of a constant difference or ratio.
According to the given question the given question the first term (a₁) of the AP is 8 and the common difference (d) is 12.
This is an AP because given in the question it self of common difference.
We know than n term of an AP is aₙ = a₁ + (n-1)d.
Given,
a₁ = 8.
a₂ = 8 + (2-1)12
a₂ = 8 + 12
a₂ = 20.
Similarly.
a₃ = 32.
a₄ = 44.
a₅ = 56.

Dos estudiantes trabajan juntos en un experimento de Física. Uno de ello, Juan, tiene un dibujo en que hay un segmento dirigido. Éste dice que se trata de una de las fuerzas con las que ambos están trabajando. Toma una regla y mide, como se muestra en la figura. Según él, la fuerza tiene una magnitud de 4.00 N.
El otro estudiante, Pedro, le replica, diciéndole que tiene un error, que él ha medido la fuerza, usando un dinamómetro y que el valor obtenido es 8.0 N.
¿Con quién concuerdas?

Step-by-step explanation:
=============================================
Explanation:
Angle JEK is composed of two rays EJ and EK
Ray EJ lands on 140 degrees while EK is on 180 degrees
Subtract the two values: 180-140 = 40
So angle JEK is 40 degrees. Since this is less than 90, the angle is acute.

How would you write 1256−4using a positive exponent? 25614 −12564 2564 −2564
Answer:
[tex](\frac{1}{1256})^4[/tex]
Step-by-step explanation:
Given
[tex]1256^{-4}[/tex]
Required
Write as an exponent of positive number
From law of indices, we have that:
[tex]a^{-b} = \frac{1}{a^b}[/tex]
So:
[tex]1256^{-4}[/tex] becomes
[tex]\frac{1}{1256^4}[/tex]
1 to the power of any digit is 1,
So, the above can be rewritten as:
[tex]\frac{1^4}{1256^4}[/tex]
Apply the following law of indices:
[tex]\frac{a^m}{b^m} = (\frac{a}{b})^m[/tex]
So:
[tex]\frac{1^4}{1256^4}[/tex] becomes
[tex](\frac{1}{1256})^4[/tex]

In the diagram below, find the value of y....
Answer:
y = 130
Step-by-step explanation:
(4x+8) + (3x-19) + (x+7) = 180
4x + 8 + 3x - 19 + x + 7 = 180
(4x + 3x + x) + (8 -19 + 7) = 180
8x - 4 = 180
8x -4 +4 = 180 +4
8x = 184
8x/8 = 184/8
x = 23
3(23) - 19 = 50
50 + y = 180
180 - 50 = y
y = 130
