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

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.

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

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.

Answers

Answer:

7500

Step-by-step explanation:

Let's call that 'whole' a variable 'x'.

Since 75 is 1% of the whole, we can write this out with numbers and symbols, remembering that 1% of a number is 0.01 times that number

75 = 0.01*x

From there, you can divide both side of the equals sign by 0.01 to find x.

75=0.01x

7500 =x

Answer:

7,500

Step-by-step explanation:

1% of 7,500 is 75

Formula : (Number x 100)/Percent Number = (75x100)/1 = 7,500/1 = 7,500

The Motion Picture Association of America is an organization of movie studios that censors movies distributed in America. The MPAA is a non-profit, private company with no connection to the U.S. government. The organization claims this is necessary to ensure the government does not violate the First Amendment rights of American citizens. It further states that because the studios police themselves, the government has no need to do so. While this fact may be true, a large number of past MPAA presidents have been ex-politicians with ties to the U.S. government. The focus of the MPAA is censorship of films. The organization rates almost all films produced and distributed by the United States. It then awards those films a rating based on the content. The MPAA does not specifically instruct film studios which scenes they should cut in order to receive a particular rating. It instead releases a general opinion as to why the film will receive the rating. The studio then has the opportunity to cut the film again and resubmit it to the MPAA for another review. If a studio chooses not to comply with the MPAA rating system for a particular film, then that film will not receive an MPAA rating. Without an MPAA rating, theater owners will not book the film in U.S. theaters. Most critics understand and support the need to protect children from exposure to inappropriate subject matter. Still, some vocal critics claim that movie studios have made use of the MPAA rating system to promote particular films. These critics say that features released by the major studios receive less censorship than features released by independent film studios. Several documentaries have come out recently that provide evidence to support this argument. The MPAA, on the other hand, defends its methods by saying its employees review a film based on an objective scale. Critics also complain that some action movie directors purposefully seek an R-rating for a film. They do so to attract larger audiences and increase ticket sales. These critics explain that if an action film has a lot of violence, then more people will go to see it. They further explain that the MPAA does not censor violence as readily as sexual content or harsh language. These critics state that if violence is just as objectionable as other adult subject matter, then the MPAA should censor it just as often. Critics of the MPAA, like film critic Roger Ebert, call for the MPAA to restructure its process to produce ratings that are more accurate.21Select the correct answer.Read the following sentence from the passage."While this fact may be true, a large number of past MPAA presidents have been ex-politicians with ties to the US government."What does the quote from the passage imply?A. The association between the MPAA presidents and the U.S. government means the organization may be influenced by the government.B. The past MPAA presidents must have been extremely trustworthy individuals because of their association with the U.S. government.C. One can assume that there have been an equal number of MPAA presidents who had no ties whatsoever with the U.S. government.D. The past presidents of the MPAA must have done something wrong because they were dismissed for service with the government.
