Arithmetic Sequences
The arithmetic sequences are those where any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:
[tex]a_n=a_1+(n-1)r[/tex]
Where
an = nth term
a1 = first term
r = common difference
n = number of the term
We are given the arithmetic sequence:
10, 12, 14, 16, ...
Where a1=10 and
r = 12 - 10 = 2
Thus the general term is:
[tex]a_n=10+(n-1)2[/tex]
Operating:
[tex]a_n=10+2n-2[/tex]
[tex]a_n=8+2n[/tex]
Answer: D
Answer:
d(n)=8+2n for n >1

Find the coordinates of the other endpoint of the segment, given its midpoint and one endpoint. (Hint: Let (x,y) be the unknown endpoint. Apply the midpoint
formula, and solve the two equations for x and y.)
midpoint (-2, -16), endpoint (-7.-9)
Given:
One endpoint of a line segment = (-7,-9)
Midpoint of the segment = (-2,-16)
To find:
The other endpoint of the given line segment.
Solution:
Let (a,b) be the other endpoint of the given line segment.
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
Using this formula, we get
[tex](-2,-16)=\left(\dfrac{-7+a}{2},\dfrac{-9+b}{2}\right)[/tex]
On comparing both sides, we get
[tex]\dfrac{-7+a}{2}=-2[/tex]
[tex]-7+a=-4[/tex]
[tex]a=-4+7[/tex]
[tex]a=3[/tex]
And,
[tex]\dfrac{-9+b}{2}=-16[/tex]
[tex]-9+b=-32[/tex]
[tex]b=-32+9[/tex]
[tex]b=-23[/tex]
Therefore, the coordinates of other endpoint are (3,-23).

Answer:
x = 12
Step-by-step explanation:
In similarity triangles angles are congruent.
∠D = ∠A
x² - 8x = 48
x² - 8x - 48 = 0
x² + 4x - 12x - 48 = 0
x(x + 4) - 12(x + 4) = 0
(x +4)(x - 12) = 0
x - 12 = 0 {Ignore x + 4 = 0, as measurements won't have negative values}
x = 12

Answer:
Step-by-step explanation:the answer to your question is 3/28
Answer:
3/28 or [tex]\frac{3}{28}[/tex]
Step-by-step explanation:
[tex]\frac{2}7}[/tex]÷[tex]\frac{8}{3}[/tex]
to divide fractions, flip the second one and multiply them.
[tex]\frac{2}{7}*\frac{3}{8}[/tex]
2 * 3 = 6
7 * 8 = 56
[tex]\frac{6}{56}[/tex]
simplify by dividing both sides by 2
[tex]\frac{3}{28}[/tex]

We notice that the first equation has a 7x7x7, x term and the second equation has a -7x−7xminus, 7, x term. These terms will cancel if we add the equations together—that is, we'll eliminate the xxx terms:
\begin{aligned} 2y+\redD{7x} &= -5 \\ +~5y\redD{-7x}&=12\\ \hline\\ 7y+0 &=7 \end{aligned}
2y+7x
+ 5y−7x
7y+0
=−5
=12
=7
Solving for yyy, we get:
\begin{aligned} 7y+0 &=7\\\\ 7y &=7\\\\ y &=\goldD{1} \end{aligned}
7y+0
7y
y
=7
=7
=1
Plugging this value back into our first equation, we solve for the other variable:
\begin{aligned} 2y+7x &= -5\\\\ 2\cdot \goldD{1}+7x &= -5\\\\ 2+7x&=-5\\\\ 7x&=-7\\\\ x&=\blueD{-1} \end{aligned}
2y+7x
2⋅1+7x
2+7x
7x
x
=−5
=−5
=−5
=−7
=−1
The solution to the system is x=\blueD{-1}x=−1x, equals, start color #11accd, minus, 1, end color #11accd, y=\goldD{1}y=1y, equals, start color #e07d10, 1, end color #e07d10.
We can check our solution by plugging these values back into the original equations. Let's try the second equation:
\begin{aligned} 5y-7x &= 12\\\\ 5\cdot\goldD{1}-7(\blueD{-1}) &\stackrel ?= 12\\\\ 5+7 &= 12 \end{aligned}

Ayla has 104 stuffed animals in her room. The ratio of teddy bears to cats is 5 to 3. How many teddy bears does she have?
Answer:
65 teddy bears
Step-by-step explanation:
Total stuffed animal = 104
Teddy bear : cats = 5 : 3
Total parts = 5+3 = 8
Number of teddy bears = [tex]\frac{5}{8}*104[/tex]
= 5 * 13
= 65
Answer:
she has 65 teddy bears
Step-by-step explanation:
if she has 104 stuffed animals and the ratio is 5/3 then to get the awnser you need 5/8
5/8*104
you get 65
find the area of the shape below, giving your answer to 1 decimal place
Answer:the answer is 150
Step-by-step explanation:multiply 10 and 15 and you get 150
Answer:
[tex] 189.25 \: {cm}^{2} [/tex]
Step-by-step explanation:
Area of the shape = Area of rectangle + Area of semicircle.
For rectangle:
Length = 15 cm
Width = 10 cm
For semicircle:
Diameter = 10 cm
Radius = 10/2 = 5 cm
Area of the shape
[tex] = lb + \frac{1}{2} \pi {r}^{2} \\ \\ = 15 \times 10 + \frac{1}{2} \times 3.14 \times {(5)}^{2} \\ \\ = 150 + \frac{1}{2} \times 3.14 \times 25 \\ \\ = 150 + 39.25 \\ \\ = 189.25 \: {cm}^{2} [/tex]

(8x-27)
(7x-4)
Answer:
x = 23
Step-by-step explanation:
(8x - 27) and (7x - 4) are corresponding angles and are congruent, so
8x - 27 = 7x - 4 ( subtract 7x from both sides )
x - 27 = - 4 ( add 27 to both sides )
x = 23
