Answer:

a

Step-by-step explanation:

The arithmetic sequence represented by the expression 3n+1 , where n represents the position of a term in the sequence is B.4,7,10,13,16,...

check:

A. 3,6,9,12,15,...

using the 4th term

first term, a = 3

4th term = 12

3n + 1

= 3(4) + 1

= 12 + 1

= 13

not applicable

B. 4,7,10,13,16,...

using the 4th term

first term, a = 4

4th term = 13

3n + 1

3(4) + 1

= 12 + 1

= 13

applicable

C. 4,5,6,7,8,...

using the 4th term

first term, a = 4

4th term = 7

3n + 1

= 3(4) + 1

= 12 + 1

= 13

not applicable

D. 3,4,5,6,7,...

using the 4th term

first term, a = 3

4th term = 6

3n + 1

= 3(4) + 1

= 12 + 1

= 13

not applicable

Therefore, arithmetic sequence represented by the expression 3n+1 , where n represents the position of a term in the sequence is B. 4, 7, 10, 13, 16,...

Answer:

55% in Decimal form: 0.55. 55% in Fraction form: 55/100. Hope this helps

Step-by-step explanation:

Answer:

Please check the explanation.

Step-by-step explanation:

Given the function

Putting all the values of y=9, 6, 0, and -3 to complete the table

FOR y=9

putting y=9

switch sides

subtract 3 from both sides

Hence,

when y=9, x=4

FOR y=6

putting y=6

switch sides

subtract 3 from both sides

Hence,

when y=6, x=2

FOR y=0

putting y=0

switch sides

subtract 3 from both sides

Hence,

when y=0, x=-2

FOR y=-3

putting y=-3

switch sides

subtract 3 from both sides

Hence,

when y=-3, x=-4

Hence, the table becomes:

x                     y

9                    4

6                    2

0                    -2

Answer:

13

Step-by-step explanation:

Ok so we will eliminate some numbers first. The width is 12, but the total on the perimeter is 24. 50-24 = 26

26 is not the length, so divide that by 2, and get 13

Proof:

x=2

13x=26

12x=24

24+26 = 50

Answer:

Step-by-step explanation:

This is a difference of squares.

√x^2 - √49  is the basic formula for factoring a difference of squares. The  idea is that the middle term has been cancelled out.

√x^2 = x

√49 = 7

(x - 7)(x + 7) is the way this factors.

(x - 7)(x + 7)

===========

(x + 7)

The (x +7) in the numerator cancels with the (x + 7) in the denominator.

The answer is (x - 7)

====================================================

She might have wanted you to do it like this.

(x + 7) || x^2  + 0x    - 49  || x     -   7

            x^2 + 7x  ........... Subtract

           ==========

                   -7x      - 49

                   -7x      - 49   ...... Subtract.

                   =============

                           0

Or she might have seen you do this

x^2 - 49          x^2        49

=======   =   ===    -   =====

x + 7                x             7

Step-by-step explanation:

I did a check digit calculator and it said that this would be the check digit

The check digit is 1.

Step-by-step explanation:

The check digit on credit is calculated by the following step:

Given:

The creditcard number: 6424 9813 2720 008d

To find :

Check digit,d

Solution:

6424 9813 2720 008d

Marking odd and even places from right side:

(e:even place,o:odd place)

e,o,e,o     e,o,e,o     e,o,e,o     e,o,e,o

6 4 2 4     9 8 1 3     2 7 2 0     0 0 8 d

Multipling every even place digit with '2'.

12,4,18,2,4,4,0,16

If two digit number then add both digits to have single digit

12,4,18,2,4,4,0,16 → 1+2,4,1+8,2,4,4,0,1+6 → 3,4,9,2,4,4,0,7

Now adding all the digits obtained in prevoius step with digits at odd place:

(3+4+9+2+4+4+0+7)+(4+4+8+3+7+0+0)= 59

The next multiply of 10 can be obtained by adding 1 to '59' that is 60. So, the check digit will be'1'.

59+1 = 60

(60 is a multiple of the number '10'.)

The check digit is 1.

Answer:

Option 4 (4, 2, 3)

Step-by-step explanation:

Coordinances for a three-dimensional coordinate system are (x, y, z).

The letter labeling each axis is always on the positive side.

Therefore, all of the coordinances must be positive.

If you look at the x,y plane you can identify that the point is two over on the y axis and four over on the x.  You can use this same strategy on the z axis to get the coordinances (4, 2, 3).

Answer:

Plz Brain -list the answer  It takes effort tnx dear

Step-by-step explanation:

From given condition

equation of line is given as,

x*cos(α)+y*sin(α)=p

& as tanα= 5/12 so from Pythagoras theorem

sinα=  5/13

​cosα=  12/13

⇒12x+5y=39

p = 3, α = tan-1 (5/12) So, tan α = 5/12 sin α = 5/13 cos α = 12/13 The equation of the line in normal form is given by By using the formula, x cos α + y sin α = p Now, substitute the values, we get 12x/13 + 5y/13 = 3 12x + 5y = 39 ∴

Answer: 10 hours

Step-by-step explanation:

First and foremost, we should note that:

Speed = Distance / Time

Total destination = 610 miles

Loretta speed = 55 mph

Time to be used by Loretta = 4 hours

Loretta's distance = Speed × Time = 55 × 4 = 220 miles

The distance to be covered by her dad will then be:

= 610 - 220

= 390 miles

Her dad's average speed = 65 mph.

Time taken by her dad will be:

= 390 / 65

= 6 hours

The number of hours to be used by the family will then be:

Time taken by Loretta + Time taken by her dad

= 4 hours + 6 hours

= 10 hours

Answer:

x = 1/5, y = 6

Step-by-step explanation:

5x + y = 7

y = 7 - 5x

Set equations equal to each other to eliminate y

7 - 5x = 20x + 2

7 = 25x + 2

5 = 25x

x = 1/5

y = 7 - 5(1/5)

y = 7 - 1

y = 6

Answer:

a. 10 + 2.50x

b. 60

c. 100

Step-by-step explanation:

a. 10 + 2.50x

b. 10 + 2.50(20)

= 10 + 50

= 60

c. 260 = 10 + 2.50x

250 = 2.50x

250/2.50 = x

x = 100
