For each sequence,find the first 4 terms and the 10th term<br> a) n+5<br> b)2n-1
dsp73

Answer:

a)6,7,8,9 and 10th term is 15.

b)1,3,5,7 and 10th term is 19.

Step-by-step explanation:

Given a) n+5

b)2n-1

Solution for  a) n+5

Taking the value of n is 1 we get the first term of the sequence;

n+5=1+5=6

Similarly taking the value of n 2,3,4 we get;

2+5=7\\3+5=8\\4+5=9

And for 10th term we take the value of n is 10 and get;

n+5=10+5=15

So the solution for 1st sequence is 6,7,8,9 and 10th term is 15.

Solution for  b)2n-1

Taking the value of n is 1 we get the first term of the sequence;

2n-1=2\times1-1=2-1=1

Similarly taking the value of n 2,3,4 we get;

2n-1=2\times2-1=4-1=3\\2\times3-1=6-1=5\\2\times4-1=8-1=7

And for 10th term we take the value of n is 10 and get;

2n-1=2\times10-1=20-1=19

So the solution for 2nd sequence is 1,3,5,7 and 10th term is 19.

Im not sure how to answer this question.

Answer:

  (-4√494)/13i +(6√494)/13k ≈ -6.8388i +0j +10.2585k

Step-by-step explanation:

To answer this question, you need to know two things:

  1) the direction of vector v

  2) the magnitude of vector u

__

<u>direction of v</u>

A direction is specified by a "unit vector", one with the proper ratio of components, and a magnitude of 1. It is found from a given vector by dividing that vector by its magnitude.

The unit vector in the v direction is ...

  v/|v| = (-2i +3k)/(√((-2)² +3²) = (-2i +3k)/√13

__

<u>magnitude of u</u>

The magnitude of vector u is ...

  |u| = √(5² +(-2)² +3²) = √38

__

Then the desired vector is ...

  (2|u|)(v/|v|) = 2√38(-2i+3k)/√13 = (-4√494)/13i +(6√494)/13k

_____

<em>Additional comment</em>

We have chosen to "rationalize the denominator" by writing √(38/13) as (√494)/13.
