Which is not the solution of x-y=0. a (1,1) b (-1,1) c(1,-1) d(1,0)

Answer»

Given : X - Y = 0

To FIND : which point is not the solution

a (1,1) b (-1,1) C(1,-1) d(1,0)

Solution:

x - y = 0

=> x = y

Any solution where x ≠ y is not a solution of x - y = 0

Hence b (-1,1) c(1,-1) d(1,0) are not solution of x - y = 0

VERIFICATION :

b (-1,1)

-1 - 1 = - 2 ≠ 0

c (1,-1)

1 - (-1 ) = 2 ≠ 0

d (1,0)

1 -0 = 1 ≠ 0

a (1,1) is the solution

as 1 - 1 = 0 = 0

(-1,1) , (1,-1) , (1,0) are not solution of x - y = 0

(1,1) is the solution

Required two numbers are 9,6

Step-by-step explanation:

Let x,(x-3) are two positive WHOLE numbers.

−6x−108=0

/* DIVIDE each term by 2, we get

\implies x^{2}-3x-54=0⟹x

−3x−54=0

/* SPLITTING the middle term, we get

\implies x^{2}-9x+6x-54=0⟹x

2

−9x+6x−54=0

\implies x(x-9)+6(x-9)=0⟹x(x−9)+6(x−9)=0

\implies (x-9)(x+6)=0⟹(x−9)(x+6)=0

\implies x-9=0 \: Or \:x+6=0⟹x−9=0Orx+6=0

Answer» Answer: Step-by-step explanation: 6 is the value of k for the consecutive terms 2k+1, 3k+3, 5k-1 which forms an AP. Given: Consecutive terms = 2k + 1, 3k + 3, 5k-1 To FIND: The value of k which forms AP in the given consecutive terms Solution: Consecutive terms = 2k + 1, 3k + 3, 5k-1 THEREFORE, by following the rule of AP that the difference of any two consecutive terms of an AP is same, we can write: The formula for the finding the common difference is 3k + 3 - 2k - 1 = 5k - 1 - 3k - 3 k + 2 = 2k - 4 By SEPARATING the common terms We get, 2k - k = 4 + 2 k = 6. Therefore, 6 is the value of k for the given consecutive terms.

For what the value of k will the consecutive term 2k+1,3 k+3,5k+1 form an A.P

Answer»

Answer:

Step-by-step explanation:

6 is the value of k for the consecutive terms 2k+1, 3k+3, 5k-1 which forms an AP.

Given:

Consecutive terms = 2k + 1, 3k + 3, 5k-1

To FIND:

The value of k which forms AP in the given consecutive terms

Solution:

Consecutive terms = 2k + 1, 3k + 3, 5k-1

THEREFORE, by following the rule of AP that the difference of any two consecutive terms of an AP is same, we can write:

The formula for the finding the common difference is

3k + 3 - 2k - 1 = 5k - 1 - 3k - 3

k + 2 = 2k - 4

By SEPARATING the common terms

We get,

2k - k = 4 + 2

k = 6.

Therefore, 6 is the value of k for the given consecutive terms.

Answer»

Given : Ferris wheel reaches the maximum height of 9m at 5s and then reaches the minimum height of 1m at 65S

To Find : a. What is the period (the length of time to complete one cycle)? b. What is the radius of the wheel?

Solution:

maximum height of 9m at 5s

minimum height of 1 m at 65s

Times = 65 - 5 = 60 sec = 1 min

Maximum Height to Minimum Height = 1/2 Cycle

Time taken for 1/2 cycle = 1 min

Time Taken for complete cycle = 1 * 2 = 2 min = 120sec

the period (the length of time to complete one cycle) = 120 Sec or 2 min

Vertical distance = 9 - 1 = 8 m

Diameter = maximum height - minimum height

Diameter = 8 m

Radius = 4 m

Answer» ANSWER: Let LENGTH be 3X. so, BREADTH =2X 35m is the Perimeter. Perimeter=2×(length+breadth) A/Q 35=2×(3x+2x) or 35=2×5x or 10x=35 hence,x=3.5m Length = 3x = 3×3.5 =10.5m Breadth =2x = 2×3.5 = 7m Ans.

36.

the distance round a rectangular cafè is 35m.The ratio of the length of the cafè to its width is 3:2 calculate the dimensions of the café

Answer»

ANSWER:

Let LENGTH be 3X.

so, BREADTH =2X

35m is the Perimeter.

Perimeter=2×(length+breadth)

A/Q

35=2×(3x+2x)

or 35=2×5x

or 10x=35

hence,x=3.5m

Length = 3x = 3×3.5 =10.5m

Breadth =2x = 2×3.5 = 7m Ans.

Answer» Answer: We can also formulate this This is called a geometric sequence, where the next term can be obtained by multiplying the prior term by a paricular number, called a common ration... So if a is our FIRST term, and R is our common ration, then our sequence would look like... a , a r , a r 2 , a r 3 ... . This has an n t h term of: a ⋅ r n − 1 where the first term is at n = 1 Your sequance is: − 5 , − 10 , − 20 , − 40 ... So a = − 5 and r = 2 n t h term = ( − 5 ) ⋅ 2 n − 1 So our next terms our n = 5 and then n = 6 So hecne using the formula: -80, -160 are the next two terms We can also take a sum of the first n terms, but thats a DIFFERENT STORY...! plz follow me and thank my answers ❤❤❤

Answer»

Answer:

We can also formulate this

This is called a geometric sequence, where the next term can be obtained by multiplying the prior term by a paricular number, called a common ration...

So if

a

is our FIRST term, and

R

is our common ration, then our sequence would look like...

a

,

a

r

,

a

r

2

,

a

r

3

...

.

This has an

n

t

h

term of:

a

⋅

r

n

−

1

where the first term is at

n

=

1

Your sequance is:

−

5

,

−

10

,

−

20

,

−

40

...

So

a

=

−

5

and

r

=

2

n

t

h

term =

(

−

5

)

⋅

2

n

−

1

So our next terms our

n

=

5

and then

n

=

6

So hecne using the formula: -80, -160 are the next two terms

We can also take a sum of the first

n

terms, but thats a DIFFERENT STORY...!
