No; a domain value has two range values.
No; a range value has two domain values.
Yes; there is only one range value for each domain value.
Yes; there is only one domain value for each range value.
Answer:
The relation is a function.
To analyze if the relationship shown is a function, you must observe that each value of the domain has a single value of the range assigned. For the given points {(-5, 6), (-2, 3), (3, 2), (6, 4)} this requirement is satisfied. Therefore, the relationship is a function.
Step-by-step explanation:
Since there is one value of y for every value of x in ( − 5 , 6 ) , ( − 2 , 3 ), ( 3 , 2 ), ( 6 , 4 ) , this relation is a function.
The relation is a function.

In a class of 32 students
the mean height of the 14 boys is 1.56 meters.
the mean height of all 32 students is 1.515 meters.
Work out the mean height of the girls.
Please help
WINNER GETS BRAINLIEST!!!!!!
Answer:
1.48 m
Step-by-step explanation:
In a class of 32 students
the mean height of the 14 boys is 1.56 meters.
the mean height of all 32 students is 1.515 meters.
Total number of students = 32
Mean height of all students = 1.515
We can obtain the sum of all student's height :
Number if students * mean height
= 32 * 1.515
= 48.48
Number of boys = 14
Mean height of boys = 1.56m
We can obtain the sum of all boys height :
Number if students * mean height
= 14 * 1.56
= 21.84
Number of girls :
All students - Number of boys
32 - 14 = 18
Sum of girls height :
48.48 - 21.84 = 26.64
Mean height of girls :
Sum of girls height / Number of girls
26.64 / 18
= 1.48 m

To find:
The common factors of given terms.
Solution:
We have,
[tex]4p^3mn^2[/tex] and [tex]2pm^2n^3[/tex]
The factor forms are
[tex]4p^3mn^2=2\times 2\times p\times p\times p\times m\times n\times n[/tex]
[tex]2pm^2n^3=2\times p\times m\times m\times n\times n\times n[/tex]
The common factors are 2, p, m, n, n. So,
Common factors = [tex]2\times p\times m\times n\times n[/tex]
= [tex]2pmn^2[/tex]
Therefore, the common factor of given terms is [tex]2pmn^2[/tex].

An angle is a figure created by two rays. The value of x is 10 units.
What is an angle?An angle is a figure created by two rays, known as the sides of the angle, that have a common terminus, known as the vertex of the angle.
The line VT bisects ∠STU, therefore, the two triangles will be similar because VT is the common line between the two triangles while ∠STV and ∠UTV are equal angles. Therefore, we can write,
[tex]\dfrac{UT}{UV} = \dfrac{ST}{SV}\\\\\dfrac{3x+2}{24} = \dfrac{12}{9}\\\\3x+2 = \dfrac{12 \times 24}{9}\\\\\\3x+2=32\\\\x=10[/tex]
Hence, the value of x is 10 units.

O (1, 3)
o (3, 2)
Answer: (2,3)
====================================================
Explanation:
The intersection point of the two lines is where the solution point is located.
The x coordinate of that intersection point is a bit smaller than x = 2, but when rounded to the nearest whole number, we would get to x = 2.
At the same time, the y coordinate of the intersection point is a bit above y = 3, which rounds to this value when rounding to the nearest whole number.
So that's how we get to (2,3)

Mike is on vacation and decides to rent a bike for part of the week. The rental cost is represented by the function c ( d ) = 25 + 20 d c(d)=25+20d , where d is the number of days of use and c ( d ) c(d) is the total cost for d days of use. How much does the bike cost Mike if he uses it for 4 days? $120
Answer:
Total cost = $105
Step-by-step explanation:
The rental cost is represented by the function c(d)=25 + 20 d.
We need to find the cost of the bike if he uses the bike for 4 days.
Put d = 4 in the given expression.
c(4)=25 + 20 (4)
=25+80
=$105
So, the cost of the bike for 4 days is $105.

A field is in the shape of a trapezium.

The field produces 7200 kilograms of barley per hectare.
One hectare is 10000 m²,
Work out how many kilograms of barley the field produces.
Answer:
36,000 kg
Step-by-step explanation:
✔️First, find the area of the trapezium field:
Area of trapezium = ½(a + b)*h
Where,
a = 210 m
b = 190 m
h = 250 m
Area of trapezium = ½(210 + 190)*250
= ½(400)*250
= 200*250
= 50,000 m²
✔️Find the kg of barley that 50,000 m² field will produce:
10,000 m² (1 ha) produces 7,200 kg
Therefore,
50,000 m² will produce:
(50,000*7,200)/10,000
= 5*7,200
= 36,000 kg of barley
