Find the domain and range of the relation of 6,5, -13, 1, -4,2, -5, 23, -10, -5
Answer:
[tex]Range = \{5,1,2,23,-5\}[/tex]
[tex]Domain = \{6,-13,-4,-5,-10\}[/tex]
Step-by-step explanation:
Given
[tex](6,5)\ (-13, 1)\ (-4,2)\ (-5, 23)\ (-10, -5)[/tex]
Required
Determine the domain and range
A relation has the following format:
[tex]\{(x_1,y_1),(x_2,y_2),(x_3,y_3),(x_4,y_4)........(x_n,y_n)\}[/tex]
The range of the relation are:
[tex]\{y_1,y_2,y_3,y_4........y_n\}[/tex]
While the domain are:
[tex]\{x_1,x_2,x_3,x_4........x_n\}[/tex]
Using this analysis, the domain of the relation is:
[tex]Domain = \{6,-13,-4,-5,-10\}[/tex]
and the Range is
[tex]Range = \{5,1,2,23,-5\}[/tex]

the amount of sod needed to cover the circular green on a golf course?
Answer:
you would need just over 261 pounds of seed for 1 acre.
Step-by-step explanation: For example, if the recommended seeding rate for a specific blend of grasses is 6 pounds per 1,000 square feet, multiply 6 by 43.56 to get 261.36. Thus you would need just over 261 pounds of seed for 1 acre.
What is the least common denominator of 7/12, 7/15, and 7/24?
Answer:
120
Step-by-step explanation:
Rewrite with only sin x and cos x.
cos 2x + sin x
1 + 3 sin x
1 + 3 sin2x
1 - 2 sin2x + sin x
1 + 2 sin2x + sin x
Answer:
[tex]cos(2x)+sin(x)=1-2\,sin^2(x)+sin(x)[/tex]
which agrees with the third option listed.
Step-by-step explanation:
I believe you meant to write the answer with only sin(x).
Use the double angle identity for the cos(2x) as shown below:
[tex]cos(2x) = cos^2(x)- sin^2(x)\\since \\cos^2(x) = 1-sin^2(x)\\then:\\cos(2x) = 1-sin^2(x)- sin^2(x)\\cos(2x)=1 - 2\,sin^2(x)[/tex]
Now we use this identity in the original expression to get:
[tex]cos(2x)+sin(x)=1-2\,sin^2(x)+sin(x)[/tex]
which agrees with the third option listed.
Math 201 Statistics week 6 discussion board?
The side of a square is measured to be 10ft with a possible error of plus/minus 0.1ft. Use linear approximation or differentials to estimate the error in the calculated area. Include units in your answer.
Answer:
±2∧
Step-by-step explanation:
x=10ft dx=±0.1
area y=x²
dy=2xdx
when x=10
dy=2×10×(±0.1)=±2
error in area=±2

Step-by-step explanation: if it not incorrect sorry for the wrong answer
Can some please help me! No one has helped me out yet, please do this is you can
Answer:
Please check the explanation below.
Step-by-step explanation:
We know that a binary relation between two sets is termed as a function which associates every element of the first set to exactly one element of the second set.In other words, in order for relation to be a function, we must make sure there must be no repetition of 'x' coordinate values, as it would violate the fundamental definition of a function.
A) (2, 5), (5, 7), (7, 9)
Here, the x-coordinates are: 2, 5, and 7
At x = 2, y = 5
At x = 5, y = 7
At x = 7, y = 9
As there is no repetition of x-coordinates.Thus, the coordinate pairs (2, 5), (5, 7), (7, 9) represent the function.
B) (2, 3), (1, 4), (2, 8),(0, 1)
Here, the x-coordinates are: 2, 1, 2 and 0
At x = 2, y = 3
At x = 1, y = 4
At x = 2, y = 8
At x = 0, y = 1
Please observe that the x-coordinate values i.e. x=2 are repeated.
Thus, the coordinate pairs (2, 3), (1, 4), (2, 8),(0, 1) does not represent the function.
C) (4, 8), (5, 8), (6, 8)
Here, the x-coordinates are: 4,5 and 6
At x = 4, y = 8
At x = 5, y = 8
At x = 6, y = 8
As there is no repetition of x-coordinates.Thus, the coordinate pairs (4, 8), (5, 8), (6, 8) represent the function.
Please note that it does not matter if y-values are repeated. Just remember, we can not have repeated x-values.D) (-1, 4), (0, -1), (8, 3)
Here, the x-coordinates are: -1, 0, and 8
At x = -1, y = 4
At x = 0, y = -1
At x = 8, y = 3
As there is no repetition of x-coordinates.Thus, the coordinate pairs (-1, 4), (0, -1), (8, 3) represent the function.
E) (1, 8), (8, 1), (1, 3)
Here, the x-coordinates are: 1, 8, and 1
At x = 1, y = 8
At x = 8, y = 1
At x = 1, y = 3
Please observe that the x-coordinate values i.e. x=1 are repeated.
Thus, the coordinate pairs (1, 8), (8, 1), (1, 3) does not represent the function.
F) (9, 0), (9, 1), (9, 2), (9, 3)
Here, the x-coordinates are: 9, 9,9 and 9
At x = 9, y = 0
At x = 9, y = 1
At x = 9, y = 2
At x = 9, y = 3
Please observe that the x-coordinate values i.e. x=9are repeated.
Thus, the coordinate pairs (9, 0), (9, 1), (9, 2), (9, 3) does not represent the function.

Arrange the integers 1,4,8,12,17,32 so that all consecutive integers add to a perfect square. Enter your answer with numbers separated by commas.
One possible answer is: 1, 8, 17, 32, 4, 12
I don't know if there's a methodical way to get this answer. I used trial and error. I started with 1 and looked through the list to see what adds to 1 to get a perfect square. That would be 8 since 1+8 = 9 = 3^2
The process is repeated but this time for 8. After a bit of guess and checking, we see that 8+17 = 25 = 5^2.
Then after 17 is 32 because 17+32 = 49 = 7^2.
Keep doing this until all of the values are used up. If you get stuck, then try backtracking to a previous branch/path where everything worked and try another fork in the road. If that doesn't work, then try starting the sequence with a completely different value (instead of 1).
Other answers may be possible. I haven't checked all possible permutations.

En una tienda se anuncia la rebaja de 20% en todos sus artículos. Rafael elije una camisa y al llegar a la caja le informan que esa camisa, por traer etiqueta roja, cuenta con un descuento adicional del 15%. Si Rafael pago $510.00, ¿cual era él precio de la camisa sin los descuentos?
9514 1404 393
Answer:
$750
Step-by-step explanation:
The 20% discount multiplies the price by (1 - 20%) = 0.80.
The 15% discount multiplies the price by (1 - 15%) = 0.85.
After applying the discounts to the initial price P, we have ...
P(0.80)(0.85) = $510
P = $510/(0.80·0.85) = $750
The price before discounts was $750.

A local restaurant only sells burgers and cokes. 3 burgers and 5 comes cost $17, while 6 burgers and 9 cokes cost $33. What’s the price of a burger?
Answer:
The price of a burger is $4 and that of cone is $1.
Step-by-step explanation:
Let the cost of burger is x and that of cone is y.
ATQ,
3x+5y = 17 ....(1)
And
6x + 9y = 33 ...(2)
Multiply equation (1) by 2.
6x + 10 y = 34 ...(3)
Subtract equation (2) from (3)
6x + 10 y-(6x + 9y) = 34 - 33
6x + 10 y-6x- 9y = 1
y = 1
Put the value of y in equation (1)
3x+5 = 17
3x = 12
x = 4
So, the price of a burger is $4 and that of the cone is $1.
