Is the following relation graphed below a function? Explain? Think about what open and closed circles mean
Given:
The graph of a relation.
To find:
Whether the given relation in the graph is a function or not.
Solution:
First we need to understand the meaning of open circles and closed circles.
Open circle: It is a unfilled circle, it means, that value is not included in the solution set.
Close circle: It is a completely filled circle, it means, that value is included in the solution set.
A relation is a function if their exist a unique y-value (output value) for each x-value (input value).
The graph of a relation is a function, if the graph intersect each vertical line at most once. It is known as vertical line test.
For the vertical lines x=-1 and x=1, the graph has only one close circle and all other vertical line intersect the graph at most once.
Since the graph passes the vertical line test, therefore it represents a function.

Ruby, Joey and sully are baking cookies together. they need 3/4 cup of flour and 1/3 cup of butter to make a dozen cookies. Ruby brought 2 cups of flour and 1/4 cup of butter, Joey brought 1 cup of flour and 1/2 cup of butter, sully brought 1 1/4 cups of flour and 3/4 cup of butter. if the students have plenty of other ingredients that they need. how many whole batches of a dozen cookies can they make.
Answer:
4 dozens.
Step-by-step explanation:
Since Ruby, Joey and Sully are baking cookies together, and they need 3/4 cup of flour and 1/3 cup of butter to make a dozen cookies, since Ruby brought 2 cups of flour and 1/4 cup of butter, Joey brought 1 cup of flour and 1/2 cup of butter, sully brought 1 1/4 cups of flour and 3/4 cup of butter, if the students have plenty of other ingredients that they need, to determine how many whole batches of a dozen cookies can they make the following calculation must be performed:
Flour: 2 + 1 + 1 1/4 = (4 1/4) / (3/4) = 4.25 / 0.75 = 5.666
Butter: 1/4 + 1/2 + 3/4 = (1 1/2) / (1/3) = 1.5 / 0.333 = 4.504
Thus, a maximum of 4 dozen cookies can be made.

Answer:
58
Step-by-step explanation:
Answer:
since the median means middle, you lay the numbers out from least to greatest.
Step-by-step explanation:
52, 72, 96, 21, 58, 40, 75 would go to
21, 40, 52, 58, 72, 75, 96.
then you cross out the numbers in a pattern so like
no more 21 and no more 96
no more 40, and no more 75
no more 52 and no more 72
this leaves you with 58!

T = 88 btw
Answer:
V = 63°
U = 29°
X = 12°
Step-by-step explanation:
given that T = 88
88 = 7x+4
88 - 4 = 7x
84 = 7x
84 = 7*12
x=12
V = 60 + 3 = 63
U = 24 + 5 = 29
88 + 63 + 29
Check : 88 + 63 + 29 .= 180

Jacob has 12 fish, and all of them are either yellow or red. There are twice as many yellow fish as red fish. How many yellow fish does Jacob have? How many red fish does Jacob have? Show your work.
Answer:
yellow : 8
Red : 4
Step-by-step explanation:
Yellow : Y and Red : R
R : Y = 12
They need to add up to 12 because its the total.
We know that yellow is twice the amount so
4×2= 8
so if yellow was to be times by 2 itd be 8 which will still add up to 12.
The number of yellow fish should be 8 and the number of redfish be 4.
Calculation of the no of yellow fish and red fish:Since Jacob has 12 fish, all of them are either yellow or red. There are twice as much yellow fish as red fish.
Here we assume the redfish be x
So, the yellow be 2x
So
2x + x = 12
3x = 12
x = 4
So, redfish should be 4
And, the yellow fish should be 8

simone buys a painting for 24000 later she sells it for 60000 how much is her percentage profit
Answer:
percentage profit = 150%
Step-by-step explanation:
percentage profit = sp - cp/cp * 100
sp is the selling price = 60000
cp is the cost price = 24000
percentage profit = 60000-24000/24000 * 100
percentage profit = 36000/24000 * 100
percentage profit = 36000/240
percentage profit = 150%

If you pay attention to the chart you will notice that medium duty fabric can last from 9000 to 15000 rubs meaning that since fabric B lasted 9200 it would be a medium duty fabric, making Fabric A light duty fabric.
A: This is INCORRECT because fabric B is medium duty
B: This is INCORRECT because Fabric B lasted longer than Fabric A
C: This is CORRECT because Fabric B is medium duty fabric
D:This is CORRECT because Fabric B lasted more rubs than Fabric A because its a more durable fabric
E: This is INCORRECT because Fabric A does not meet the requirements to be a Medium duty fabric.

Mel took out a loan of $40,000 at 14 percent on March 16, 2015 which will be due on January 9, 2016. Using exact interest the amount of Mel's interest cost is:
Answer:
the interest cost is $4,679.45
Step-by-step explanation:
The computation of the interest cost is shown below:
= Loan amount × rate of interest × given no of days ÷ total no of days in a year
= $40,000 × 14% × 305 days ÷ 365 days
= $4,679.45
hence, the interest cost is $4,679.45
