30 points math question HELP PLEASE! will give brainliest!

Zepler [3.9K]

Answer:

F'=12.1243557 N

Step-by-step explanation:

Let the horizontal component of force he is pulling with be F' Newtons and the force applied be F Newtons.

$\therefore \cos \theta = \frac{Horizontal \: Force}{Force \: applied}$

$\therefore \cos \theta = \frac{F'}{F}$

$\therefore F'=F\cos \theta$

$\therefore F'=14.\cos 30\degree$

$\therefore F'=14.\frac{\sqrt 3}{2}$

$\therefore F'=7\sqrt 3$

$\therefore F'=12.1243557 \: N$

If a₁ = 4 and an = 5an-1 then find the value of a5.

igor_vitrenko [27]

The value of $a_{5}$ is 2500, when $a_{1}=4$ and $5a_{n-1}$ .

Given that, $a_{1}=4$ and $5a_{n-1}$ .

We need to find the value of $a_{5}$ .

<h3>What is an arithmetic sequence?</h3>

An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.

Now, to find the value of $a_{5}$ :

$a_{2} =5a_{2-1}=5a_{1}=5 \times4=20$

$a_{3} =5a_{3-1}=5a_{2}=5 \times20=100$

$a_{4} =5a_{4-1}=5a_{3}=5 \times100=500$

$a_{5} =5a_{5-1}=5a_{4}=5 \times500=2500$

Therefore, the value of $a_{5}$ is 2500.
