Answer:
A - Not Function
B - Function
C - Function
D - Not Function
E - Function
Step-by-step explanation:
For a relation to be a function, each value of input should have exactly one output. Which means that for one value of x, there should only one value of y. If the relation has repetition of x in its ordered pairs, it means that for one value of x, there are two or more values of y, hence the relation is not a function
(Consult the diagram below)
A - {(6,12),(3,1),(−1,13),(6,4)}As x = 6 is being repeat, it means that x=6 has two values of y that are 12 and 4. IT IS NOT A FUNCTION.
B - {(−1,−2),(−4,−4),(0,−5),(7,−5)}No repetition of x, IT IS A FUNCTION.
C - {(−5,1),(4,10),(5,10),(6,7)}No repetition of x, IT IS A FUNCTION.
D - {(−1,4),(1,6),(−1,−2),(0,7)}As x = -1 is being repeat, it means that x=-1 has two values of y that are 4 and -2. IT IS NOT A FUNCTION.
E - {(−2,8),(2,1),(−4,8),(7,9)}No repetition of x, IT IS A FUNCTION.

As the time increases, the distance from the floor decreases by 40 cm per second. You find 40 by taking (6,1140) and (9,1020). The slope formula is y2 - y1 over x2- x1. Plug in the variables and you get (1020-1140)/(9-6)= -120/3= -40.

Trapezoid RSTU with vertices R(-5, 15), S(0, 10), T(-5, 5) and U(-15, 5): scale factor = 1/5, centered at the origin
Answers
Answer:
R'(-1,3) , S'(0,2) , T'(-1,1), U'(-3,1)
Step-by-step explanation:
To find the vertices of a point after a dilation simply multiply the x and y values of each given coordinate by the scale factor.
So to find the vertices of Trapezoid RSTU after a dilation centered at the origin with a scale factor of 1/5 we would multiply the x and y values of the given coordinates of Trapezoid RSTU by 1/5.
Given Coordinates: R(-5, 15), S(0, 10), T(-5, 5) and U(-15, 5)
Scale Factor: 1/5
R(-5, 15) -----> ( -5 * 1/5 = -1 , 15 * 1/5 = 3 ) -----> (-1,3)
S(0,10) -----> ( 0 * 1/5 = 0 , 10 * 1/5 = 2 ) -----> (0,2)
T(-5,5) -----> ( -5 * 1/5 = -1 , 5 * 1/5 = 1 ) -----> (-1,1)
U(-15,5) -----> (-15 * 1/5 = -3 , 5 * 1/5 = 1 ) -----> (-3,1)
So the coordinates of Trapezoid RSTU after a dilation with a scale factor of 1/5 are R'(-1,3) , S'(0,2) , T'(-1,1), U'(-3,1)

Answer:
1/32
Step-by-step explanation:
The probability of rolling a 6 on a 6-sided die is 1/6, and the probability of rolling a 4 on a 6-sided die is also 1/6.
Assuming that the rolls are independent (i.e., the outcome of one roll does not affect the outcome of the other roll), the probability of rolling a 6 and then a 4 is the product of the probabilities of each individual event:
Probability of rolling a 6 and then a 4 = (Probability of rolling a 6) x (Probability of rolling a 4)
= (1/6) x (1/6)
= 1/36
Therefore, the probability of rolling a 6 and then a 4 on a 6-sided die rolled twice is 1/36, or approximately 0.0278 (2.78%).

Answers
Answer:
Answer C.
Step-by-step explanation:
If x= -5 and y= 0.25
Equation A : 4 * 0.25 - 3 * -5 = 16
Equation B: -(-5) -8*0.25=3
These are only coordinates that satisfy the equation.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given coordinates: (-5, 0.25)
Equation A: 4y - 3x= 16
So, 4(0.25)- 3 (-5)
= 1+ 15
= 16
and, Equation B: -x -8y= 3
So, -(-5) -8 (0.25)
= 5 - 2
= 3
Hence, these are only coordinates that satisfy the equation.

South Pole Expedition
Your Outdoor Adventures class is providing guidance to a group that is on an expedition to the South Pole. There are 5 people on the expedition.
Due to the extreme climate and conditions, each person in the group needs to consume 5600 calories per day. The table shows the three foods that will make up their total daily calories, along with the number of calories per unit and the daily needs by percentage.
[ attached image ]
The map shows the current location of the group, as well as the location of the South Pole and the base camp. Each unit on the grid represents 5 miles.
[ attached image ]
The group thought there was enough food for all 5 group members to complete the trip, with each person getting the required 5600 calories per day. They discover that 2 of the crates they brought are missing.
Each crate contains:
• 80 biscuits
• 50 packages of pemmican
• 10 packages of butter and cocoa
Using the map, create a plan for the rest of the trip that includes taking as many group members as possible to the South Pole, and back to base camp, passing through the groups current location, while sending the rest of the group members directly back to base camp. Remember that each person must have 5600 calories of food per day until he or she gets back to base camp.
Be sure to explain how you came up with your plan. Include all work necessary to support your answer.
Answers
Answer: the answer is that each 80 calories is worth 40 daily calories
Step-by-step explanation:
To be able to pal the calories consumption, one can total the amount of people together (5people x 5groups = 25) and then begin to share the food using 5600 calories per day.
What is calorie?This is known to be a form of a measurement, as it is the the amount of energy that is often given off when the human body breaks down food.
Since there are 25 people that needs 5600 calories per day.
The numbers of crate were not given so answer will be limited to 2 crate.
2 crate has:
160 biscuit100 pemmican20 butter and cocoaFrom the table, having one single biscuit, pemmican and butter and cocoa gives 100% of the daily calories needs.
Therefore each person should have a single biscuit, pemmican and butter and cocoa.

Answer: Ok, fast. Here we go: Basically the number sequence increases by 3 every number. 7+3=10 10+3=13. Etc, etc.
Step-by-step explanation:
So just go from 19 (which is the 5th term) and count up.
19+3=22(6th term) 22+3=25(7th term) 25+3=28(8th term) 28+3=31(9th Term) 31+3=34(10th term)
34 is your answer.
a: We can quickly find the answer by multiplying 3 by 5, then by adding the quantity of the numbers to 19.
\(5(3) + 19\)
15 + 19 = 34
Therefore, the 10th term in this number sequence is 34.
b: n represents the numbered term of the number sequence.
3 can represent x in the expression we make.
\(3x = n\)
Therefore, a possible expression for this number sequence is 3x = n.

−4= 1 /20 x−5
Step 2: Flip the equation.
1/ 20 x−5=−4
Step 3: Add 5 to both sides.
1 /20 x−5+5=−4+5
1 /20 x=1

Answer:
Mean = 33.7
Median = 34.5
Mode = 34
Range = 33
After adding 26....
mean decreases by 0.7
median decreases by 0.5
mode is 34
range is 33
Step-by-step explanation:
mean = sum of all the data values/number of data values
= (18 + 19 + 20 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7
To find median arrange the values in increasing order, find the mid value
If the number of data points is even, find the average of the mid 2 data values
Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51
Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5
The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once
Mode = 34
The range is highest - lowest = 51 - 18 = 33
After we add 26, we get the following data set arranged
18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51
we can calculate the stats using the same technique as above
We get the following values
mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33
median = 34
mode = 34
range = 51-18 = 33
To find the decrease in mean and median subtract from the first set of values
