-4 0
2 0
5 7
x y
-5 1
-3 -2
-1 -5
Step-by-step explanation:
the second one (with the -5 as x values) is not a function, because the valid x value -5 has more than one associated different solution value y.
for a function a valid x value can lead only to exactly one result y value.
1.) From a group of 8 people, 5 will each win $1,000. How many different winning groups are
possible?
A.) 56
B.) 6720
C.) 168
D.) 336
Anwser 6720 ways different
Step-by-step explanation:
In this case, we must calculate the different ways using the permutation formula:
nPr = n! / (n - r)!
where n is the total number of people and r would come being the group of person that you want to put together the groups, therefore n = 8 and r = 5
replacing:
8P5 = 8! / (8 - 5)!
8P5 = 6720
That is to say that there are 6720 ways different winning groups are possible

an = 8 + (n - 1) × 4
an = 8 + 4n - 4
an = 4n + 4
Answer:
[tex]a_{n}[/tex] = 4n + 4
Step-by-step explanation:
The nth term (explicit formula) of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 8 and d = a₂ - a₁ = 12 - 8 = 4 , then
[tex]a_{n}[/tex] = 8 +4(n - 1) = 8 + 4n - 4 = 4n + 4

Monique can choose 20 different sets of 3 of the books
What is a combination?The set of books she can select from the library is an illustration of combination (or selection)
The expression that represents combination is represented as:
[tex]^nC_r = \frac{n!}{(n - r)!r!}[/tex]
Where:
The total number of books [tex]n = 6[/tex]The set of books to check out [tex]r = 3[/tex]So, we have:
[tex]^6C_3 = \frac{6!}{(6 - 3)!3!}[/tex]

If the parallel sides of a trapezium are 2 cm apart and their sum is 10 cm then find its area.
Answer:
[tex] {10cm}^{2} [/tex]Step-by-step explanation:
Given,
Sum of parallel sides of the trapezium = 10 cm
Distance between or Height of the trapezium = 2 cm
As we know,
Area of a trapezium
[tex] = \frac{1}{2} \times (sum \: of \: parallel \: sides) \times height[/tex]
Therefore,
Area of the given trapezium will be,
[tex] = \frac{1}{2} \times 10 \: cm \times 2 \: cm[/tex]
(On Simplification )= 1 × 10 cm × 1 cm
(On multiplying)[tex] = 10 {cm}^{2} [/tex]
Hence,
The Area of the trapezium is 10 sq.cm (Ans)
Given :
The parallel sides of a trapezium are 2 cm apart and their sum is 10 cm.To Find :
Its area.Solution :
We know that,
[tex]{ \qquad \: \pmb{ \dfrac{1}{2} \times (sum \: of \: the \: parallel \: sides) \times height} = \pmb{Area_{(trapezium)}}}[/tex]
Now, Substituting the given values in the formula :
[tex]\qquad { \dashrightarrow \: { \sf{ \dfrac{1}{2} \times 10\: \times 2 \: = {Area_{(trapezium)}}}}}[/tex]
[tex]\qquad { \dashrightarrow \: { \sf{ \dfrac{1}{2} \times 20 = {Area_{(trapezium)}}}}}[/tex]
[tex]\qquad { \dashrightarrow \: { \sf{ \dfrac{20}{2} = {Area_{(trapezium)}}}}}[/tex]
[tex]\qquad { \dashrightarrow \: { \sf{ 10 = {Area_{(trapezium)}}}}}[/tex]
⠀
Hence,
The area of the trapezium = 10 cm² .Using the matrix solver on your calculator, find the solution to the system of

Answer:
A.Domain:{x\x is a real number }
Range:{y\y>5}
Asymptote :y=5
Step-by-step explanation:
We are given that a function
We have to find the domain, range and asymptote of h(x).
It is exponential function therefore, it is defined for all values of x.
Hence, domain of h(x)={x| x is a real number}
Substitute x=0 then we get
(a^0=1)
Hence, range of h(x)={y|y>5}
For exponential function,
Horizontal asymptote: when
Apply limit
Hence, the horizontal asymptote y=5.

The Sydney Harbour Bridge is approximately 1200 metres long. A model of the bridge is built with a scale of 1:6000. What is the length of the model?
Pick one:
5cm
20cm
200cm
720cm
--------------------
scale = 1:6000
so
1200 : 6000 = 0.2m
0.2m = 20 cm
Answer:
20cm
Step-by-step explanation:
«A scale of 1:6000» means the model is smaller than the bridge by a factor of 6000. We can also make up a proportion [tex]\dfrac{1}{6000}=\dfrac{x}{1200}[/tex], where the left side is the scale, x is the model length, 1200 is the bridge length (in meters). So, finding x or just dividing 1200 by 6000, we get 0.2 meters. Provided 1 m = 100 cm, 0.2 m is 0.2 × 100 = 20 cm.
