Is F={56,777,1,2} a subset of G={2,78,64,333,1,7,56,77,900}?

Answers

Answer:

Step-by-step explanation:

F is not a subset of G because not every element in F lives in G. Even through 56, 1 and 2, all live in G, and are elements of F, 777 is an element of F but is not an element of G.

(If there is a typo, and every element in F is in fact an element in G, then the answer would be yes, F is a subset of G)

We can see that element 777 is not in set G. Hence the set F is not a subset of set G.

A set is a collection of elements not necessarily arranged in a particular pattern.

For a set A to be a subset of another set B, all elements of the set must be found in set B.

For the given set F={56,777,1,2}, we can see that the element 777 is not in the set G. Hence the set F is not a subset of set G.

Sam can ride his bike 4.2 kilometers in 6 minutes. Amanda can ride her bike 3.2 kilometers in 8 minutes. Jesse can ride his bike 3.0 kilometers in 5 minutes.

Which rider might go farther in 1 minute?

Answers

Answer:

jesse or sam i think its sam by a little bit.

Step-by-step explanation:

Answer:

Sam

Step-by-step explanation:

Find all of their speeds to find how far they will go in 1 minute, by dividing the number of kilometers by the number of minutes:

Sam

4.2/6

= 0.7 km/min

Amanda

3.2/8

= 0.4 km/min

Jesse

3/5

= 0.6 km/min

Since 0.7 is the greatest number, that means Sam is the rider that will go the farthest in one minute.

Four different mathematics books, six different physics books, and two different chemistry books are to be arranged on a shelf. How many different arrangements are possible if a) The books in each particular subject must all stand together b) Only the mathematics books must stand together

Answers

Answer:

a) 207,360 ways

b)8,709,120 ways

Step-by-step explanation:

Total number of subjects= 3

Number of mathematics books = 4

Number of physics books = 6

Number of chemistry books = 2

Part a:

Number of possible arrangement s= 3! 4! 6! 2!= 6*24*720*2= 207360 ways

In this we have included 3! because the books have to be placed in such a manner that the books in each particular subject must all stand together.

Part b:

Similarly the mathematics books must stand together so they are treated as

The total number of books will be

Physics books + Chemistry books+ Mathematics books= 6+2+1(treated as single) = 9

But there are 4 different mathematics books so these can be arranged in 4 ways.

Total number of ways in which these books can be arranged = 9! 4!= 8709120 ways.

What is 1092 using the polynomial identity (a+b)2=a2+2ab+b2 ?

Drag and drop the correct responses into the boxes.

Let the smaller value a = Response area and the larger value b = Response area. Then a2+2ab+b2 is Response area. This can be simplified to Response area. So, 1092 is equal to Response area.

Answers

Answer:

Step-by-step explanation:

The fill ups is

Smallest number, a= 9

Largest number, b= 100

a²+ 2ab+ b² can be written as 9²+ 2. 9. 100 + 100²

What is Polynomial?

A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminates in mathematics.

Given:

Here the smallest number can be taken as 9.

and, here we have 109² then the number can be split as 100 + 9.

Thus, the largest number is 100.

Now, a²+ 2ab+ b² can be written as 9²+ 2. 9. 100 + 100² which can be simplified as 11881.

Debates have raged among members of Congress, business owners, and the general public. the president has expressed his thoughts on numerous occasions as well. The conversations seem to boil down to one question: Do the benefits of space travel outweigh the cost? A logical look at the question makes the answer quite apparent. NASAs space program is worth preserving at any cost.Put simply, NASA creates jobs. Jobs, in return, help the economy. A single space project can employ hundreds of workers from high level, top security jobs to lower level, yet important role players. Scientists are assigned to solve problems. Engineers are contracted to build prototypes. Truckers are hired to transport materials. Large corporations are paid for contributions, earning profits so they may hire more employees.The work of NASA also pays huge dividends for the environment. Studying Earth from space provides keen insight into many areas. Scientists monitor the ozone layer. They track the effects of global warming. They study patterns of dangerous storms. They test the possibility of space colonies. All of these activities offer hope to our increasingly overcrowded planet. The work of NASA often leads to advances in technology. Solving the mysteries of space creates solutions that help elsewhere. The Jaws of Life save victims in car accidents. The technology came from NASA research. The artificial heart did, as well. The list goes on. Architects, athletes, and autoworkers have benefited from space-related discoveries. NASA has enhanced everything from shoes to food. You likely come into contact with something improved by NASA nearly every day.It is impossible to list all the benefits of a thriving space program. It is equally impossible to predict how many new benefits are within our grasp. To find them, we must keep reaching for the stars.
