Answer:
[tex]a_n = 1 + 5(n-1)[/tex]
$36
Step-by-step explanation:
I think the part that is confusing you is how to read the math syntax.
The part that says "[tex]a_n=1, if\ n=1[/tex]" just means that a=1 is your starting number. The n=1 is the first iteration.
The part that says "[tex]a_{n}=a_{n-1}+5\ , if\ n>1[/tex]" just means that you add 5 to the previous number every iteration.
They want you to find the number at 8th iteration, n=8. So lets work it out.
n=1: a= 1
n=2: a= 1+5 = 6
n=3: a= 6+5 = 11
n=4: a= 11+5 = 16
n=5: a= 16+5 = 21
n=6: a= 21+5 = 26
n=7: a=26+5 = 31
n=8: a= 31+5 = 36
Or you can use the shortcut:
You're always adding by 5 each time and starting with 1, so:
[tex]a_n = 1 + 5(n-1)[/tex]
where n=8 for the 8th round.
[tex]a_n = 1 + 5(8-1) = 36[/tex]

Carlos and his family are driving to California for vacation. The trip is 1,146 miles and they drive at an average speed of 56 mph. Which equation would give the number of miles remaining until they reach their destination, M, in terms of h, the number of hours they have driven? А. M= 1,146 + 56h
B. M= 56 - 1,146h
C. M= 56 + 1,146h
D. M= 1,146 - 56h
Answer:
D. M = 1,146 - 56h
Step-by-step explanation:
I beleive that this answer is the most reasonable because we arent adding miles to the trip we are taking away. Also subtracting from 56 would result in a negative answer and that really doen't make sense because they still have more miles to travel before they reach their destination.
Help me please!
Correct answer get's brainliest :D
answer:
step by step explanation:
make all numbers the same decimal,fraction or percentage and then compare
3/8=37.5%
-2.8=20.8%
0.053=5.3%
-2.8%
ascending means from smallest to biggest so the answer would be 0.053
The area of a rhombus is 16 cm 2 . If the length of one diagonal is 4 cm, find the
length of the other diagonal.
Let, the length of the other diagonal be X
According to the Question:
We know that:
▶ Area of rhombus = ½ × d1 × d2
⇒ 16 = ½ × 4 × d2
⇒ d2 = 32/4
⇒ 8 cm

Step-by-step explanation:
The full pie chart will equal 100%
So we can add all the percentages together and then subtract that percentage from 100 and whatever's left is the parentage that they attend school.
12+3+5+10+5+35
70
100-70
30

Graph the solution of 1/4x≤2. Please use a virtual graph or draw your own.
Answer:
The solution of [tex]\frac{1}{4}x \leq 2[/tex] is [tex]\mathbf{x\leq 8}[/tex]
Graph of the solution is attached in the figure below.
Step-by-step explanation:
We need to the graph the solution of [tex]\frac{1}{4}x \leq 2[/tex]
First we will solve to find value of x
[tex]\frac{1}{4}x \leq 2[/tex]
Multiply both sides by 4
[tex]\frac{1}{4}x\times 4 \leq 2\times 4 \\x\leq 8[/tex]
So, the solution of [tex]\frac{1}{4}x \leq 2[/tex] is [tex]\mathbf{x\leq 8}[/tex]
Graph of the solution is attached in the figure below.
The graph contains both number line and on graph paper also.

Answer:
43°
Step-by-step explanation:
-the interior angle of a triangle always adds up to 180°
- angles that form a straight line always adds up to 180°
- the angle at 75° has the angle of 105° to add up to 180°
- the triangle needs a full degree of 180, but only affs up to 137° (105° + 32°) so you have to subtract the 137° from the total amount you need(180°) which gives you the answer of 43°
Answer:
Step-by-step explanation:
it cant be 73° then it would look about the same size as 75°
and it cant be 15° cause it would look smaller than 32°.
so in my Opinion it looks like it would be 43°.

sean has to face a big problem but he becomes stronger as a result which saying best summarizes the change in Sean?
A.A switch in tie saves nine
B.be careful what you wish for
C.pride comes before a fall
D.every cloud has a silver lining
Please help me I WILL give brainless <33
Answer: D. every cloud has a silver lining
The cloud represents a dark, scary, or sad moment. This is in contrast to the sun which metaphorically represents energy and happiness. The cloud sometimes covers up the sun to cover up those happy moments so to speak.
Despite the cloud being present, there's a silver lining to the cloud which represents some positive aspect a person didn't expect to happen. In this case, the problem allows Sean to get stronger. So this is an opportunity for his growth.

Answer:
(3). h = 4√6 units ; (5). x = 3√21 units
Step-by-step explanation:
(3). "h" is geometric mean
h² = 6 × 16 = 96
h = 4√6 units
(5). h = √(7 × 20) = √140 = 2√35
x² = 7² + 140 = 189
x = 3√21 units

Answer: [tex]\sqrt{\frac{A}{\pi } }[/tex] = r
Step-by-step explanation:
The goal in this problem is to isolate the single variable, r. The original equation is A = pir^2. The first step to attempt to get r on its own is to divide each side of the equation by pi.
A = pir^2
A/pi = pir^2/pi
A/pi = r^2
Next, find the square root of each side to get r on its own:
A/pi = r^2
sqrt(A/pi) = sqrt (r^2)
[tex]\sqrt{\frac{A}{\pi } }[/tex] = r
What is the slope of the line that passes through the following g points

Mike is mixing paint for his walls. He mixes
1/6 gallon blue paint and
4/9 gallon green paint in a large container.
What fraction represents the total amount of paint Mike mixes?
Answer: 11/18
=======================================================
Explanation:
We need to add the fractions, but first we need to get each fraction to have the LCD (lowest common denominator) of 18
18 is the LCM of the denominators 6 and 9
The fraction 1/6 turns into 3/18 when multiplying top and bottom by 3
The fraction 4/9 turns into 8/18 after multiplying top and bottom by 2
Therefore,
(1/6) + (4/9) = (3/18) + (8/18) = (3+8)/18 = 11/18
So Mike has a total of 11/18 of a gallon of paint when combining the two given amounts 1/6 a gallon of blue paint and 4/9 of a gallon of green paint.

Answer:
y = (1/12)x^2
Step-by-step explanation:
The vertex of this parabola is halfway between (0, 3) and the directrix, y = -3; that is, it's at (0, 0).
The applicable equation for this vertical parabola is 4py = x^2, where p is the distance between the vertex and the focus. Here that distance is p = 3.
Thus, 4py = x^2 becomes 4(3)y = x^2, or 12y = x^2, or y = (1/12)x^2.
Have a good day!

Can someone help me calculate angles?
Answer:
1.45
2. 135
Explanation:
1. With a triangle all angles have to add up to 180, so what you would do is add up both angles we already know (43+92=135), then we subtract the sum from 180, (180-135=45) now you know the third angle.
2. Just like a triangle, when finding angles on a line, it has to add up to 180. We already know that point M has an angle of 45 from the last problem, so all we have to do is subtract 45 from 180 (180-45=135). THats the measurement on TMS
Gcf/ greatest common factor and / LCM least common multiple Mang Andoy is going to put in trays of 6 eggs and 12 eggs. What is the smallest number of eggs that Mang Andoy can put using the tray. 1. What is asked? _________________________________ 2. What are given facts? _________________________________ 3. How will you solve the problem? ___________________________ 4. How is the solution done? ______________________________ 5. What is the answer to the problem? ___________________________
Answer with explanantion:
1. What is asked? The smallest number of eggs that Mang Andoy can put using the tray.
2. What are given facts? Two kinds of tray (One can have 6 eggs , other can have 12 eggs)
3. How will you solve the problem? We need to find LCM of 6 and 12.
4. How is the solution done?
Prime factorization of 6 and 12:
6=2 x 3
12 = 2 x 2 x 3
LCM(6,12) = 2 x 2 x 3 = 12
5. What is the answer to the problem? The smallest number of eggs that Mang Andoy can put using the tray = 12
