Answer:
6, 13, 20, 27, 34
arithmetic sequence
Step-by-step explanation:
"Start with 6" means the first term is 6.
"Add 7 repeatedly" means each term is formed by adding 7 to the one before it:
6 +7 = 13
13 +7 = 20
20 +7 = 27
27 +7 = 34
So, the first 5 terms are ...
6, 13, 20, 27, 34
_____
Any sequence in which terms have a common difference is an *arithmetic* sequence. You know these terms have a common difference of 7, because that's the number you added to each term to get to the next term. 13-6 = 7; 20-13 = 7; 27-20 = 7; and so on.

Step-by-step explanation:
What is the cos of angle y
Answer:
its cos:48/80
Step-by-step explanation:
cos-1(48/80)=53.13
For this case we have by definition of trigonometric relations that the cosine of an angle is given by the leg adjacent to said angle on the hypotenuse of the triangle. So:
[tex]Cos (Y) = \frac {64} {80} = \frac {32} {40} = \frac {16} {20} = \frac {8} {10} = \frac {4} {5}[/tex]
After simplifying we have to:
[tex]Cos (Y) = \frac {4} {5}[/tex]
ANswer:
[tex]Cos (Y) = \frac {4} {5}=0.8[/tex]

Drag the correct classification for each graph into the boxes to complete the table.
neither even or odd, odd, even
Answer:
Odd, neither, neither
Step-by-step explanation:
A function is even if f(x) = f(-x). That means that it passes through the origin and is symmetrical about the y-axis.
A function is odd if f(x) = -f(-x). That means that it passes through the origin and is symmetrical about the origin.
The first graph, the line, passes through the origin and is symmetrical about the origin. So it is odd.
The second graph does not pass through the origin, nor is it symmetrical. So it is neither odd nor even.
The third graph does not pass through the origin, nor is it symmetrical about the y-axis. So it is neither odd nor even.

A piggy bank was filled during a calendar year, by a coin placed in it every day except some Sundays. If the quantity of coins in the piggy bank is distributed evenly among 6 children, two coins remain. If this quantity is distributed evenly among 7 children, four coins remain. If the quantity of coins in the piggy bank is distributed evenly among 8 children, how many coins will remain?
Answer:
probably 6////////////
Answer:
The answer is 6
Step-by-step explanation:
In a year there is 365 days.
From the first condition, 6x + 2 = to a unknown number of coins
From the second condition, 7x + 4 = to the same number of unknown coins.
The number which satisfies this given condition is 326 coins.
If we divide this number by 8 to share it among 8 students =
326 ÷ 8 = 40 coins/ student and 6 coins remaining. Therefore, the answer is
6 Coins

The ceiling of Katie’s living room is a square that is 12 ft long on each side. To decorate for a party, she plans to hang crepe paper around the perimeter of the ceiling and then from each corner to the opposite corner. Katie can buy rolls that each contain 10 ft of crepe paper. What is the minimum number of rolls she should buy? Show work.
Answer:
The minimum number of rolls to buy is 9
Step-by-step explanation:
step 1
Find the perimeter of the ceiling of Katie’s living room
The perimeter of a square is equal to
[tex]P=4b[/tex]
where
b is the length side of the square
we have
[tex]b=12\ ft[/tex]
so
[tex]P=4(12)=48\ ft[/tex]
step 2
Find the length side of the diagonals of the ceiling
Applying Pythagoras theorem
[tex]d=\sqrt{12^{2} +12^{2}}\\ \\d=\sqrt{288}=16.97\ ft[/tex]
step 3
Find the total crepe paper needed
Sum the perimeter plus two times the length side of the diagonal
[tex]48\ ft+2*(16.97\ ft)=81.94\ ft[/tex]
step 4
Find the number of rolls needed
we know that
Each roll contain 10 ft of crepe paper
so
[tex]81.94/10=8.19\ rolls[/tex]
Round up
[tex]8.19=9\ rolls[/tex]
The minimum number of rolls to buy is 9
Final answer:
Katie needs to purchase 9 rolls of crepe paper to decorate her living room ceiling. The calculation includes both the perimeter and the diagonals of her square ceiling.
Explanation:
The ceiling of Katie’s living room is a square that is 12 ft long on each side. To calculate the amount of crepe paper she needs for the perimeter, we multiply the length of one side by 4, since a square has four equal sides: 12 ft × 4 = 48 ft. To calculate the length needed to hang crepe paper from corner to corner, we use the Pythagorean theorem for a square, which says the diagonal is equal to the side length multiplied by the square root of 2: 12 ft × √2 ≈ 12 ft × 1.414 ≈ 16.97 ft. Since there are two diagonals, we need twice this amount: 16.97 ft × 2 ≈ 33.94 ft. Adding the perimeter and diagonals, we get a total of 48 ft + 33.94 ft = 81.94 ft.
Each roll of crepe paper contains 10 ft. To find out the number of rolls needed, we divide the total footage by 10 ft per roll: 81.94 ft ÷ 10 ft/roll ≈ 8.194 rolls. Since Katie can't buy a fraction of a roll, she will need to purchase 9 rolls to have enough crepe paper to decorate her living room ceiling.
Chico is financing a car for $9,550 and an APR 8.9 percent for 3 years. What is his monthly payment if the monthly payment per $100 is $3.18?
Answer:
the monthly payment is $303.69
Step-by-step explanation:
this is how i got it:
9,550 divided by 100= 95.5
95.5 x 3.18= 303.69
so the monthly payment it $303.69
Final answer:
To find Chico's monthly car payment, divide the total loan amount by $100 to determine the number of units and multiply by the monthly payment per unit, resulting in a monthly payment of $303.69.
Explanation:
The student's question relates to calculating the monthly payment of a car financing plan. To determine Chico's monthly payment for his car loan, we can use the provided information that each $100 of the loan requires a $3.18 monthly payment at an APR of 8.9%. Since Chico is financing $9,550, we first divide this amount by $100 to find the number of 'units' of $100 in the total loan amount. We then multiply that number by the monthly payment per $100 to find the total monthly payment.
Calculate the number of $100 units in the total loan amount: $9,550 / $100 = 95.5 units.
Multiply the number of units by the monthly payment per unit: 95.5 units * $3.18/unit = $303.69.
Therefore, Chico's monthly payment for the car would be $303.69.
2.) The inverse of the function y = 7x + 5 is y = x+5/7
A. True
B. False
Answer:it is false
Step-by-step explanation:
Since we are talking about inverse of a function. we would be dealing with reversal. An inverse function is function that reverses another function. Getting the inverse will require reversing the numerator and denominator. This means that the numerator becomes the denominator and the denominator becomes the numerator.
The function given is
y = 7x + 5
Let us solve to see whether the inverse is is y = x+5/7 is true or false
The numerator is 7x + 5 and the denominator is 1
The inverse becomes 1 / (7x + 5 )
So it is false

Mike and alice recycled 147 bottles altogether. Mike recycled 6 times as many bottles as Alice. How many bottles did alive recycle
total=147
a:m
1:6 =7
147÷7=21
21×1=21
alice recycled 21 bottles
Answer:
21
Step-by-step explanation:
We have an equation in the first sentence we are given. Mike and Alice together recycled 147 bottles, so in equation form that looks like this:
M + A = 147.
That alone doesn't do us much good because we have 2 unknowns. The next sentence gives us Mike's number of bottles based on Alice's. If the number Mike recycles is 6 times as many as Alice, replace the word "is" with an "=" and "6 times as many as Alice" with 6A to get:
M = 6A
Now we can go back to the first equation and replace M with 6A:
6A + A = 147
Now we only have A's. That's a good thing. Solve for A:
7A = 147
A = 21
If a || b and _____, then a || c.
b perpendicular c
b || c
a perpendicular c
b perpendicular a
The answer is:
The correct option, is the second option:
b || c ( b and c are parallel).
Why?To solve the problem, let's remember the following relationship:
If:
[tex]a=b[/tex]
and
[tex]b=c[/tex]
Then:
[tex]a=c[/tex]
So, from the statement we know that a and b are parallel (a || b), so, if a and c are parallel ( a || c) it means that b and c are parallel ( b || c).
Hence, the correct option is:
The second option, b || c ( b and c are parallel)

The owner of a car dealership keeps track of the monthly car sales for the salespeople at the dealership. What is the range for the number of cars sold?
Answer:
The answer is 13- cedric Rhen
Step-by-step explanation:
The range for the number of cars sold at the dealership is 13 cars, calculated by subtracting the lowest sales number (4) from the highest (17).
The range for the number of cars sold by the salespeople at the dealership can be calculated by finding the difference between the maximum and minimum sales numbers. First, we identify the highest and lowest sales figures from the list provided. The highest number of sales is 17 (by Mark) and the lowest is 4 (by Manuel).
Now, subtract the minimum from the maximum to get the range: 17 (max) - 4 (min) = 13.
Therefore, the range for the number of cars sold is 13 cars.

The Palm Springs tramway takes passengers from the hot valley and brings them 5800 feet up into the cool San Jacinto mountains. The 15 minute ride costs about $20. Suppose the mountain terminal is 11520 feet West of the valley terminal. Use the Pythagorean Theorem to find the length of the cable that connects the two terminals
.Length of cable = _____ feet
Round your answer to 2 decimal places
Answer:
12,897.69 ft
Step-by-step explanation:
The cable is assumed to be the hypotenuse of a right triangle with side lengths 11520 ft and 5800 ft. Then the length of it (in feet) is ...
cable length = √(11520² +5800²) = √166,350,400 ≈ 12,897.69 . . . feet
_____
Comment on the question
A cable that long will have considerable sag, so even an answer rounded to the nearest 10 ft is probably in error by quite a bit.

The graph of the function y = x2 is shown. How will the graph change if the equation is changed to y = 2x^2?
Answer:
The parabola will become narrower.
Step-by-step explanation:
Because of the coefficient 2, every value of x² is doubled, which means higher value on the same X coordinate, compared to the y = x² function.
Answer: B) The parabola will become narrower
Step-by-step explanation:
The vertex form of a quadratic equation is: y = a (x - h)² + k where
"a" is the vertical stretch (shrink/compression if |a| < 1)(h, k) is the vertexIn the given equation of y = 2x², the a-value has increased so it is stretched. When the graph stretches, the sides will get closer together thus the parabola will become narrower.

Jane had several stamps. She gave 10 of them to her friend. Afterwards, Jane's mom bought her twice as many stamps as she had in the beginning. How many stamps did Jane have in the beginning if she now has a total of 50 stamps?
Answer:
Jane had 20 stamps in the beginning
Step-by-step explanation:
* Lets study the information in the problem
- Jane has unknown numbers of stamps
- She gave 10 of them to her friend
- Her mom give her twice as many stamps as she had in the beginning
* To solve the problem let the unknown numbers of stamps = x
∵ Jane had at the beginning x stamps
- She gave her friend 10 of them
∴ The rest with her = x - 10 stamps
- Her mom gave her twice as many stamps as she had in the beginning
∵ She had at the beginning x stamps
∴ Her mom gave her 2 × x = 2x
∴ The number of stamps with her now = x - 10 + 2x stamps
- She has now 50 stamps
∴ x - 10 + 2x = 50 ⇒ add the like term
∴ 3x - 10 = 50 ⇒ add 10 to both sides
∴ 3x = 60 ⇒ divide both sides by 3
∴ x = 20
∴ Jane had 20 stamps in the beginning

If the company has set a goal of producing 20 radios for a cost of 2,500, which statement is true?
(1.Plant A is producing at a cost that is farthest from the goal
(2. Plant C is producing at a cost greater than the goal.
(3. Plant B is at the goal
Answer: 2) Plant C is producing at a cost greater than the goal.
Explains which plant is achieving the goal set by the company regarding radio production costs.
Correct Statement: Plant B is at the goal of producing 20 radios for a cost of $2,500.
Explanation:
Plant A being farthest from the goal is inaccurate since the question mentions Plant B is producing at the goal cost.
Plant C producing at a cost greater than the goal is incorrect as Plant B is already reaching the goal cost.
Plant B is indeed at the goal, as stated in the question, producing 20 radios for a cost of $2,500.
