There is n arithmetic means between 2 and 46 such that the first mean: last mean is 1:7. find the value of n.
Mariulka [41]

Answer:

<h3>n = 10</h3>

Step-by-step explanation:

The nth term of an arithmetic sequence is expressed as:

Tn  = a + (n-1)d

a is the first term

n is the number of terms

d is the common difference

Let the sequence be 2, T1, T2, T3...Tn, 46

The common difference is expressed as d = b-a/n+1

T1 = 2 + d

Given b = 46 and a = 2

d = 46-2/n+1

d = 44/n+1

T1 = 2 + (44/n+1)

T1 = 2(n+1)+44/n+1

T1 = 2n+2+44/n+1

T1 = 2n+46/n+1

Similarly;

Tn =  2 + nd

Tn = 2 + n(44/n+1)

Tn = 2 + 44n/n+1

Tn = 2(n+1)+44n/n+1

Tn = (2n+2+44n)/n+1

Tn = 46n+2/n+1

If the ratio of the first mean to last mean is 1:7 then T1/Tn = 1/7

(2n+46/n+1)÷(46n+2/n+1) = 1/7

2n+46/n+1 * n+1/46n+2 = 1/7

2n+46/46n+2 = 1/7

Cross multiply and solve for n:

46n + 2 = 7(2n + 46)

46n + 2 = 14n + 322

46n - 14n = 322-2

32n = 320

n = 320/32

n = 10

<em>Hence the value of n is 10</em>

BRAINLIEST!PLEASE HELP ME
Oxana [17]

Answer: (3, 5)

<u>Step-by-step explanation:</u>

y = x + 2 is already in Slope-Intercept format

  • b = 2: Plot +2 on the y-axis
  • m = 1: Count up 1 and right 1 from "b" to plot the next point

y = -x + 8 is already in Slope-Intercept format

  • b = 8: Plot +8 on the y-axis
  • m = -1: Count down 1 and right 1 from "b" to plot the next point

A rectangle has a height of b3 + b2 and a width of b2 + 76 + 4.
zaharov [31]

Answer:

The area is:

{b}^{5}  + 8 {b}^{4}  + 11 {b}^{3} +  4 {b}^{2}

Step-by-step explanation:

To find the area of a rectangle, multiply the width by the height (I'll be using x for b, as it is easier when writing the equations):

a =  ({x}^{ 3}  +  {x}^{2} )( {x}^{2}  + 7x + 4) \\ a =  {x}^{5}  +  7{x}^{4}  + 4 {x}^{3}   \\ +  {x}^{4}   + 7 {x}^{3}  + 4 {x}^{2}  \\ a =  {x}^{5}  + 8 {x}^{4}  + 11 {x}^{3} +  4 {x}^{2}
