2. The algebraic form of an arithmetic sequence is 4 n+1.

erma4kov [3.2K]

Answer:

Given:-

The algebraic form of an arithmetic sequence is 4n+1.

To find:-

common difference.

first term

remainder when each term of the sequence is divided by 4.

Solution:-

Given,

and n = 1,2,3...

Now,

If n = 2,

The sequence is 5 ,9,13..

Hence, the first term is 5.

Common difference :

=> d =

=> 9- 5

=> d = 4.

Hence, common difference is 4.

Remainder :

=> 5/4 = 4(4) +1

Here, remainder =1

=> 9/4 = 4(2)+1

Here, remainder =1

=> 13/4 = 4 (3)+1

Here , remainder = 1.

Therefore, the remainder when each term of this sequence is divided by 4 is 1 .

An airplane lands on a runway with a velocity of 150 m/s. How far will it travel until it stops if its rate of

Akimi4 [234]

Answer:

3750 m

Step-by-step explanation:

This question can be solved using law of equation of motion

$v^2 = u^2 + 2as$

where v is the final velocity

u is the initial velocity

a is the acceleration

and

s is the distance travelled

________________________________

given

final velocity = v = 0 since it is given that plane stops

u = 150 m/s

a = -3m/s2

using the above values in the given equation

$v^2 = u^2 + 2as\\0 = 150*2 + 2*-3s\\0 = 22500 - 6s\\=> 6s = 22500\\=> s = 22500/6 = 3750$

Thus, plane will travel 3750 m before it stops.
