Flying to Kimpala with a tail wind a plane averaged 158km/hr. On the return trip the plane only average 112km/hr. While flying b

The speed of wind and speed of plane in still air are 23 and 135 km/h respectively.

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

Let the speed of wind and speed of plane in still air are w and p km/h respectively.

The effective speed on onward journey was

$p+w=158$ ................(1)

The effective speed on return journey was

$p-w=112$ ..............(2)

Adding equation (1) and equation (2) we get,

⇒ $(p+w)+(p-w) = 158+112$

⇒ $2p = 270$

⇒ $p = 135$

Putting value of $p = 135$ in $p+w=158$ we get:

⇒ $p+w=158$

⇒ $135+w=158$

⇒ $w=23$

Therefore ,The speed of wind and speed of plane in still air are 23 and 135 km/h respectively.

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.
