106,184,267,357,456,?​

Answer:

[tex]\fbox {566}[/tex]

Step-by-step explanation:

Identifying the pattern :

184 - 106 = 78

267 - 184 = 83

357 - 267 = 90

456 - 357 = 99

Here, we see the difference between the numbers increases by a value of 2 between consecutive terms.

  • 83 - 78 = 5
  • 90 - 83 = 7
  • 7 - 5 = +2

Then, the next addend will be :

  • 99 - 90 + 2
  • 9 + 2
  • 11

The term is :

  • 456 + 99 + 11
  • 456 + 110
  • 566
1 6. Find the CI on 64000 for 1- 2 A Cr years at 5% p.a., the interest being compounded half-yearly​

Answer:

[tex]\fbox {Interest = 1600}[/tex]

Step-by-step explanation:

Formula :

[tex]\boxed {A = P (1 + \frac{r}{n})^{nt}}[/tex]

Given :

  1. A = 64000
  2. t = 1/2 years
  3. r = 5% = 0.05
  4. n = 2

Solving :

  • A = 64000 (1 + 0.05/2)^{2 x 1/2}
  • A = 64000 (1.025)
  • A = 64000 x 1025/1000
  • A = 64 x 1025
  • A = 65600
  • Interest = A - P
  • Interest = 65600 - 64000
  • Interest = 1600
The unit vector parallel to the resultant of R₁-(2,4,-5) and R₂ = (1,2,3) is ​

Answer:

The unit vector will [tex]\hat{R}= \frac{(3i+6j -2 k)}{ 7 }[/tex]

Explanation:

let the resultant be R

thus unit. vector in the direction of R is given by

[tex]\hat{R}= \frac{\vec{R}}{ |R| }[/tex]

[tex] \vec{R} = R_1+R_2 [/tex]

[tex] \vec{R} = (2i+4j -5 k) + (1i + 2j + 3k)[/tex]

[tex] \vec{R} = (3i+6j -2 k) [/tex]

[tex] | \vec{R} | = \sqrt{( {3}^{2} + {6}^{2} + {( - 2)}^{2} ) } \\ = \sqrt{49} \\ = 7[/tex]

[tex]\hat{R}= \frac{(3i+6j -2 k)}{ 7 }[/tex]
