If the sum of the first nterms of an AP is 3 + 4n2.Find the 3rd, the 10th andthe nth terms.
Sum of first n terms of an AP – Sn = 3 + 4n²
Find:the 3rd, the 10th andthe nth terms.
Solution:Substitute the value of n as 1 to find the first term of the given AP.
(Sum of first 1 terms is nothing but the first term).
Hence,
⟹ S₁ = a = 3 + (4)(1)²
⟹ a = 3 + 4
⟹ a = 7
Now,
Substitute the value of n as 2 to find the sum of first 2 terms.
⟹ S₂ = a + a₂ = 3 + 4(2)²
⟹ a + a₂ = 3 + 16
Substitute the value of a here.
⟹ 7 + a₂ = 19
⟹ a₂ = 19 - 7
⟹ a₂ = 12
We know,
nth term of an AP – an = a + (n - 1)d
So,
a₂ = a + (2 - 1)d = a₂ = a + d.
Subtract a from a₂.
⟹ a + d - a = 12 - 7
⟹ d = 5
Now,
nth term = an = 12 + (n - 1)(5)
⟹ an = 12 + 5n - 5
⟹ an = 5n + 7
Substitute n as 3 & 10 , to find the 3rd & 10th terms.
★ a₃ = 5(3) + 7
⟹ a₃ = 8 + 7
⟹ a₃ = 15
★ a₁₀ = 5(10) + 7
⟹ a₁₀ = 50 + 7
⟹ a₁₀ = 57
Therefore,
Third term is 15
Tenth term is 57
nth term is 5n + 7.

FIRST TO ANSWER GET BRAINLIST OR WHATEVER ITS CALLED Which transformation will map quadrilateral ABCD onto itself?
OT(x, y) - (-x, -y)
OT(x,y) - (x,-y)
0 T(x, y) (y,x)
T(x,y) - (-y, x)
Answer:
Option (1)
Step-by-step explanation:
Since, quadrilateral ABCD shown on the graph is a parallelogram,
It will overlap itself when rotated by 180° about the origin.
In other words, all vertices of the given parallelogram will overlap itself when they are rotated by 180° about the origin.
Rule for the rotation of a point about the origin is,
(x, y) → (-x, -y)
Therefore, Option (1) will be the answer.

Leticia esta leyendo una novela, el primer dia leyo un tercio de las paginas del libro, el segundo dia leyo dos octavos de paginas del libro y el tercer dia leyo tres novenos de las paginas del libro.¿Cuanto le falta por leer
Answer:
A Leticia le falta siete doceavos de las páginas del libro por leer.
Step-by-step explanation:
Constatamos que la proporción de páginas por leer es igual a la totalidad de páginas menos las proporciones leídas durante los tres días:
[tex]r = 1 -r_{1}-r_{2}-r_{3}[/tex] (Eq. 1)
Donde:
[tex]r_{1}[/tex] - Proporción leída en el primer día, adimensional.
[tex]r_{2}[/tex] - Proporción leída en el segundo día, adimensional.
[tex]r_{3}[/tex] - Proporción leída en el tercer día, adimensional.
Si sabemos que [tex]r_{1} = \frac{1}{3}[/tex], [tex]r_{2} = \frac{2}{8}[/tex] y [tex]r_{3} = \frac{3}{9}[/tex], entonces la proporción de páginas por leer es:
[tex]r = 1-\frac{1}{3}-\frac{2}{8}-\frac{3}{9}[/tex]
[tex]r = 1-\frac{1}{3}-\frac{1}{4}-\frac{1}{3}[/tex]
[tex]r = 1-\frac{2}{3}-\frac{1}{4}[/tex]
[tex]r = 1-\frac{8-3}{12}[/tex]
[tex]r = 1-\frac{5}{12}[/tex]
[tex]r = \frac{7}{12}[/tex]
A Leticia le falta siete doceavos de las páginas del libro por leer.

1 1/2 times 2 equals
Answer:
3
Step-by-step explanation:
========================================
Work Shown:
The mixed number 1 & 1/2 converts to
1 & 1/2 = 1 + 1/2 = 1 + 0.5 = 1.5
Then we multiply it with 2 getting
(1 & 1/2) times 2 = 1.5 times 2 = 3
-------------------
Another way you could do it
1 & 1/2 = 1 + 1/2 = 2/2 + 1/2 = 3/2
(1 & 1/2) times 2 = (3/2) times 2 = (3/2) * (2/1) = 6/2 = 3

Question text The diameter of a hydrogen atom is about \(5\times10^{-11}\) meter. Suppose \(8.4\times10^8\) hydrogen atoms were arranged side by side in a straight line. Multiply these numbers to find the length of this line of atoms. What is the length in scientific notation?
Answer: 4.2 x 10⁻⁴m
Step-by-step explanation: Scientific Notation is a method of writing a very large or very small number. It consists in any real number between 1 and 10 multiplied by any power of 10 (positive or negative).
The diameter of hydrogen is 5x10⁻¹¹m. There are 8.4x10⁸ atoms of hydrogen.
To determine the length of the line of atoms, you could add the diameter the number of atoms or multiply the diameter by the number of atoms:
L = 5x10⁻¹¹ * 8.4x10⁸
As it is multiplication, you can mutiply the numbers and then add the power of 10, since they are in the same base:
L = 42 x 10⁻³m
or moving comma to the left:
L = 4.2 x 10⁻⁴m
The length of the line of hydrogen atoms, in scientific notation is 4.2x10⁻⁴m
