A. The set is a function since each element in the domain has a different element in the range.
B. The set is a function since each element in the range has a different element in the domain.
C. The set is a not a function since each element in the domain has a different element in the range.
D. The set is a not function since each element in the range has a different element in the domain.

The set does not represent a function, option (D) the set is a not function since each element in the range has a different element in the domain is correct.

What is a function?

It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a set of ordered pairs:

{(0,1.2),(3,2),(-1.2,3), (4, -2),(1,-1.2),(1,2,4)}

We know there are four main types of mapping that are:

One to one, one to many, many to one, and many to many.

In the case of one to one, and many to one. the relation is a function but in the case of one to many and many to many relations is not a function.

As we can see in the set of ordered pairs the x values are repeated which is also not a property of a function hence it is not representing the function.

Thus, the set does not represent a function, option (D) the set is a not function since each element in the range has a different element in the domain is correct.

Find the missing side length for each triangle.

Answers

Answer:

for triangle ABC side AC is 13         and for triangle DEF side ED is 24

Step-by-step explanation:

Here Is a trapozhum and a squnro, The lengths of the parnllel sides of the
trapezhum are 10 cm and 14 cm, The helght of tho trhpoziurm is 12 cm. The nren of
the squpre is equal to the aren of the trapeziurn. Work out the perimeter of the
square

Answers

Answer:

48 cm

Step-by-step explanation:

Here Is a trapezium and a square, The lengths of the parallel sides of the  trapezium are 10 cm and 14 cm, The height of the trapezium is 12 cm. The area of  the square is equal to the area of the trapezium. Work out the perimeter of the  square.

Solution:

The area of the trapezium is given by:

A = (1/2)(a + b)h

where h is the height of the trapezium = 12 cm, a and b are the parallel sides. Given that a = 10 cm, b = 14 cm, hence:

A = (1/2)(10 + 14)12 = 144 cm²

Area of trapezium = Area of square

Area of square = 144 cm²

Area of square = length * length = length²

length² = 144 cm²

length = √144 = 12 cm

Perimeter = 4 * length = 4 * 12 cm = 48 cm

Do 16/2, which gives you eight for every necklace. Then do 192/8 which would give you 24. So, she would need 24 jars for 192 necklaces.

Answer:

16÷2=8

8÷192=24

its 24

all you have to do is divide the 16 and 2 to see how many is in each jar and how much they have done then just just divide that number with 192.

Adia is placing soil in flower pots. She has 58 quart of soil. She needs 54 quarts of soil to fill one whole flower pot. Use the drop-down menus to complete the statements below about the flower pots that Adia can fill with the soil she has.

Answers

Answer:

1 whole flower pot

Step-by-step explanation:

Given that:

Quart of soil Adia has = 58

Quart of soil to fill a whole flower pot = 54

The pot Adia can fill. With the soil he has :

Quart of soil Adia has / Quart of soil to fill a whole flower pot

= 58 / 54

= 1.074 pots

What is intersection?

The intersection of two sets is the set of all those elements which are common to both of the sets.

here, we have,

Solution:

Let students who likes tennis be represented by set T.

Let students who likes football be represented by set F.

Let students who likes baseball be represented by set B.

Given that

Number of students who likes tennis that is n(T) = 18

Number of students who likes football that is n(F) = 25

Number of students who likes tennis and football = n( T ∩ F ) = 10

Number of students who likes tennis and baseball = n( T ∩ B ) = 13

Number of students who likes football and baseball = n( F ∩ B ) = 20

Number of students who likes all three sports = n(T ∩ F ∩ B ) = 8

Number of students who likes none of the sports = 9.

Determining number of students who like only tennis and football:

number of students who like only tennis and football = Number of students who likes tennis and football - Number of students who likes all three sports

so number of students who like only tennis and football

= n( T ∩ F ) - n(T ∩ F ∩ B )  

= 10 – 8

= 2

Determining number of students who like only tennis and baseball:

number of students who like only tennis and baseball = Number of students who likes tennis and baseball - Number of students who likes all three sports

so number of students who like only tennis and baseball

= n( T ∩ B ) - n(T ∩ F ∩ B )  

= 13 – 8

= 5

Determining number of students who like only baseball and football:

number of students who like only baseball and football = Number of students who likes baseball and football - Number of students who likes all three sports

so number of students who like only baseball and football

= n( B∩ F ) - n(T ∩ F ∩ B)  

= 20 – 8

= 12

Summarizing the result :

number of students who like only tennis and football = 2

number of students who like only tennis and baseball = 5

number of students who like only baseball and football = 12.

A pebble falls off of a cliff at a height of
784 ft. If the equation for height as a
function of time is
h(t) = -16t2 + initial height where t is time
in seconds and h(t) is height in feet, how
many seconds will it take for the pebble
to hit the ground?

Answers

Answer:

7 seconds

Step-by-step explanation:

You would get 49 from doing -784 divided by -16 then you do the square root of 49 which is 7

ANSWER= 7 seconds

The time taken by the pebble to hit the ground will be = 7 seconds

What is an Algebraic Equation?

Expression we get when operations such as addition , subtraction , multiplication , division , are operated upon on variable and constants.

Equation of height as a function of time = h(t) = - 16 (t^2)

cliff is at a height of = 784 feet

comparing both the above equation , we get

-16 (t^2) = 784

t^2 = 49

t = 7 seconds

The time taken by the pebble to hit the ground will be = 7 seconds
