The quadratic sequence answered  this way .

Quadratic sequences are sequences that include an term. They can be identified by the fact that the differences between the terms are not equal, but the second differences between terms are equal.

According to the question

Quadratic sequences are given the next term is :

1> 7 11 17 25  

First difference between terms

11 - 7 = 4

17 - 11 = 6

25 - 17 = 8  

Second difference between terms

6 - 4 = 2

8 - 6 = 2

Therefore, next term : First last difference + Second difference  + Last Term

                                   : 8+2 = 10

                                   : 25 + 10 = 35

2> 6 12 22 36

First difference between terms

12 - 6 = 6

22 - 12 = 10

36 - 22 = 14

Second difference between terms

10 - 6 = 4

14 - 10 = 4

Therefore, 1st next term : First last difference + Second difference  + Last Term

                                     :  14 + 4 = 18

                                     :  36+ 18 = 54

2nd next term : First last difference + Second difference  + Last Term

                                     :  18 + 4 = 22

                                     :  22 + 54 = 76

3rd next term : First last difference + Second difference  + Last Term

                                     :   22 + 4 = 26

                                     :   76 + 26 = 102

4th next term : First last difference + Second difference  + Last Term

                                    :    26 + 4 = 30

                                     :   76 + 26 = 102

3> nth term of a quadratic sequence = [tex]n^{2} - 2n + 8[/tex]

first three terms of this sequence :

1st term of the sequence : n = 1

substituting value of n

[tex]1^{2} - 2 + 8[/tex]

= 7

2nd term of the sequence : n = 2

substituting value of n

[tex]2^{2} - 2*2 + 8[/tex]

= 8

3rd term of the sequence : n = 3

substituting value of n

[tex]3^{2} - 2*3 + 8[/tex]

= 17 - 6

= 11

4> Quadratic sequence has an nth term :  [tex]2n^{2} + 3n -1[/tex]

6th term of the sequence : n = 6

substituting value of n

[tex]2(6)^{2} + 3*6 -1[/tex]

36*2 + 18 -1

= 89

5> Quadratic sequence has an nth term : [tex]n^{2} - 6n + 7[/tex]

term = 23

therefore,

23 = [tex]n^{2} - 6n + 7[/tex]

0 = [tex]n^{2} - 6n - 16[/tex]

solving the equation

[tex]n^{2} - (8-2)n - 16 = 0[/tex]

n(n- 8) + 2 (n - 8) = 0

(n-8) (n+2) = 0

n = 8 , -2

As term can not be negative , so n = 8

Therefore, term 8 of Quadratic sequence  : [tex]n^{2} - 6n + 7[/tex] is 23 .

6> First 5 terms of a quadratic sequence :

4 11 20 31 44

expression for the nth term of this quadratic sequence:

As general form of quadratic sequence is : [tex]an^{2}+bn +c[/tex]

now for n= 1

a + b + c = 4 -------------------(1)

now for n= 2

[tex]a2^{2}+b*2 +c[/tex] = 11

4a + 2b + c = 11 ---------------------------(2)

now for n= 3

[tex]a3^{2}+b*3 +c[/tex] = 20

9a + 3b + c = 20  ----------------------------------(3)

solving equation (1) , (2) & (3)

a = 1 , b = 4 , c = -1

now , substituting the value in general equation

[tex]= n^{2}+4n -1[/tex]

Hence, The nth term of this quadratic sequence [tex]= n^{2}+4n -1[/tex]

7>The first 5 terms of a quadratic sequence : 4 10 18 28 40

the nth term of this quadratic sequence :

9a + 3b + c = 18  ----------------------------------(3)

solving equation (1) , (2) & (3)

a = -4 , b = 18 , c = -10

now , substituting the value in general equation

[tex]= -4n^{2}+18n -10[/tex]

Hence, The nth term of this quadratic sequence [tex]= -4n^{2}+18n -10[/tex]

8>First 5 terms of a quadratic sequence : 9 17 29 45 65

the nth term of this quadratic sequence :

As general form of quadratic sequence is : [tex]an^{2}+bn +c[/tex]

now for n= 1

a + b + c = 9 -------------------(1)

now for n= 2

[tex]a2^{2}+b*2 +c[/tex] = 17

4a + 2b + c = 17 ---------------------------(2)

now for n= 3

[tex]a3^{2}+b*3 +c[/tex] = 29

9a + 3b + c = 29  ----------------------------------(3)

solving equation (1) , (2) & (3)

a = 2 , b = 2 , c = 5

now , substituting the value in general equation

[tex]= 2n^{2}+2n +5[/tex]

Hence, The nth term of this quadratic sequence [tex]= 2n^{2}+2n +5[/tex]

9> Pattern is not given (incomplete question)

10> The nth term of a sequence is : [tex]n^{2} + 3n[/tex]

Two consecutive terms in the sequence have a difference of 38

The two terms of the sequence  :

N2 - N1 = 38

substituting n as n2 and n1

[tex](N_{2}) ^{2} + 3N_{2} - (N_{1}) ^{2} - 3N_{1}[/tex] = 38

[tex](N_{2}) ^{2} - (N_{1}) ^{2} + 3N_{2} - 3N_{1} = 38[/tex]

[tex](N_{2} - N_{1} ) (N_{2} + N_{1})+ 3(N_{2} - N_{1}) = 38[/tex]

[tex](N_{2} - N_{1} ) [N_{2} + N_{1}+ 3] = 1*38\\\ (as (N_{2} - N_{1} = 1 ) consecutive terms)[/tex]

now,

[tex](N_{2} - N_{1} ) = 1 ,\\\ [N_{2} + N_{1}+ 3] = 38[/tex]

solving both equations

[tex]N_{2} =18\\ N_{1} = 17[/tex]

Hence, two terms of sequence are 18th and 17th the whose difference in 38 .

11> The sequence:  [tex]n^{2} - 4n + 21[/tex]

To proof  the sequence is positive always

As n cannot be negative

let n = 0

substituting the value in equation we get

+ve

As we conclude in equation +ve part is larger than -ve part always ,

so this equation is always be +ve for any value of n .

#SPJ2

Answer: 56%

Step-by-step explanation: To write the fraction 28/50 as a percent, remember that a percent is a ratio that compares a number to 100.

So we need to find a fraction that's equivalent

to 28/50 that has a 100 in the denominator.

To do this, we set up a proportion.

So we have 28/50 = n/100.

To find the value of n, we first find the fraction that

is equivalent to 28/50 that has a denominator of 100.

If we multiply both the numerator and denominator of

28/50 by 2, we can see that 28/50 = 56/100.

So 28/50 is equal to 56/100 or 56%.

Answer:

Part 1: G)52%  H)28%  I)19%   J)75%   K)95%

Part 2: 88%

Step-by-step explanation: I did math stuff lol, converted the decimal into a percent

Ex: 13/25= 0.52

0.52= 52%

Answer:

g. 52%

h. 28%

i. 19%

j. 75%

k. 95%

l. 88%

Step-by-step explanation:

g. 13/25

The denominator is currently 25. We must multiply it by 4 to reach 100. By converting the denominator to 100, the numerator will give us the answer to the percentage. However, when multiplying one side of the fraction (the denominator), we must also do the same to the other side of the fraction (the numerator).

Hence:

13 × 4 / 25 × 4

52/100

Since the denominator is 100, we can confidently say the answer is 52%

h. 7/25

Multiply by the numerator and the denominator by 4 so that the denominator equals 100.

7 × 4 / 25 × 4

28/100

28%

i. 19/100

The denominator for this fraction is 100, meaning the percentage is the numerator:

19%

j. 3/4

To get from 4 to 100, we must multiply by 25. What we do to the denominator, we must do to the numerator.

3 × 25 / 4 × 25

75/100

75%

k. 19/20

In order to change the denoninator to 100, multiply the denominator by 5 (20 × 5 = 100). Multiply by 5 to the numerator too to get the percentage.

19 × 5 / 20 × 5

95/100

95%

l. Out of 25 questions, Maria answered 22 correctly. If we write this as a fraction, we would put the total number (of questions) as the denominator with the correctly answered (number of questions) as the numerator:

22/25

We have to convert the denominator to read as 100 instead of 25. To do so, we must multiply 25 by 4. Whatever we do to the denominator, we must do to the numerator which means multiply the numerator by 4 as well.

22 × 4 / 25 × 4

88/100

Volume of a cylinder = πr²h

Height,h = 12.75 cm

π = 3.14

Radius,r = r

Volume of the cylinder = 1,000 cm³

Volume of a cylinder = πr²h

110°+x=180°

x=180°-110°

x=70°

equation for y

according to the question

[tex]11 {0}^{o} + {40}^{o} + y = 18 {0}^{o} [/tex]

[tex]15 {0}^{o} + y = 180^{o} [/tex]

[tex]y = 18 {0}^{o} - 15 {0}^{o} [/tex]

[tex]y = 3 {0}^{o} [/tex]

equation for z

according to the question

90°+x+z=180°

90°+70°+z=180° (since x=70°)

160°+z=180°

z=180°-160°

z=20°

Answer:

X= 70

Z= 20

y= 30°

Step-by-step explanation:

Finding X:

Sum of angle in a straight line is 180

Therefore X = 180-110

Finding z:

Sum of angle in triangle is 180, and it’s a right angled triangle (90°)

Z= 180-(x+90)

Z= 180-( 70+90)

Finding y, look at the big triangle ABC:

There’s a right angle and <C is 40°,

Therefore <B is 180-(40+90)= 50°

<B= y + z

50° = 20° + y

y= 30°

Answer: The weight = 33.75kg

Step-by-step explanation:

Given that  

one cubic metre of ice weight is 80 kg

which is mathematically written as
