Nicholas has 8 pieces of rope that are 4 yards each. He uses 4 pieces that are each 4 feet long.

For the following exercises, determine whether each of the following relations is a function.

RSB [31]

Answer:

The relation {(2,1),(3,2),(-1,1),(0,-2)} is a function because the domain {2,3,-1,0} and range {1,2,1,-2} of the relation is paired exactly only once.

Step-by-step explanation:

The given relation is {(2,1),(3,2),(-1,1),(0,-2)}.

It is required to determine the relation is a function.

Step 1 of 1

The given relation is {(2,1),(3,2),(-1,1),(0,-2)}.

This relation shows that the domain of the relation {2,3,-1,0} is paired with one element of the range {1,2,1,-2}.

Hence, the relation is a function.

Find the perimeter of the figure. Please

kramer

The dashed line labeled as 6 is the diameter of the circular part of the figure.

The circumference of a circle is it's perimeter, so we need to find half the circumference first.

The formula for circumference is PI x diameter, since we need half we will divide the total circumference by 2.

Circumference = 3.14 x 6 = 18.85 / 2 = 9.425

Now we add that to the other 3 dimensions for total perimeter:

9.425 + 9 + 9 +6 = 33.425

You may need to round the answer, you didn't say if it needed to be rounded a certain way.

What is the <br> Area of Circles:<br> Shaded area:

Rudiy27

Answer:

each square takes up a 10 by 10 square is you divide it into to four pieces then you use the formula for area of a circle

Step-by-step explanation:

1) 10 x 10

Find the diameter which is 5

Use the area equation Pie r squared

Divide the diameter by 2 to get radius

3.14 x 2.5 squared

19.625

at that 4 times

You get are of circles

And Shaded area is 19.625

Find the values of x and y if (2x + y, 2) = (1, x - y).

m_a_m_a [10]

Answer:

We have, 2x+y=3 .......(1)

xy=1....(2)

In equation (2), we get

y=

x

1

..........(3)

y put in the equation (1)

2x+

=3

2x

−3x+1=0

2x

−3x−1x+1=0

2x(x−1)−1(x−1)=0

x=1, x=

1

We take the value of x=1

x value put in equation (1)

2(1)+y=3

y=3−2

y=1

x=1

x and y value put (x+y)

x−y

=(1+1)

(1−1)

=2

0

=1

Hence, this is the answer

A tournament is being run between two teams, A and B. This is a 2- tournament meaning that the first team to win 2 games is the

natta225 [31]

Answer:

Step-by-step explanation:

For first game PA = 1/3

For second game PA = 1/3 ( If A is not lost in first game )

= 2/5 (If A is lost in first game )

For conclusion of game in three matches :

If A wins , the probability is

PA , PB , PA = 1/3 X 2/3 X 3/5 = 6/45

PB , PA , PA = 2/3 X 3/5 X 1/3 = 6/45

If B wins

PA, PB, PB = 1/3 X 2/3 X 2/5 = 4/ 45

PB, PA , PB = 2/3 X 3/5 X 2/3 = 4 / 15

Total probability of conclusion of game in 3 matches

= 6/45 +6/45 + 4/45 +4/15 = 28/45

b )

For the game concluding in 2 matches , the probability are as follows

PA,PA = 1/3 X 1/3 = 1/9

PBPB = 2/3 X 2/5 = 4 / 15

Total probability

= 1/9 + 4/15 = 17/45

So PA = 1/9 / 17/45

= 5/17
