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.

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

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

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

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

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

$\therefore F'=7\sqrt 3$

$\therefore F'=12.1243557 \: N$

1/3 ( x - 10) = -4 ???

Pepsi [2]

Answer:

$x = - 2$

Step-by-step explanation:

1) Simplify 1/3 ( x - 10) to x-10/3.

$\frac{x - 10}{3} = - 4$

2) Multiply both sides by 3.

$x - 10 = - 4 \times 3$

Simplify 4 × 3 to 12.

$x - 10 = - 12$

4) Add 10 to both sides.

$x = - 12 + 10$

5) Simplify -12 + 10 to -2.

$x = - 2$

So, therefor, the answer is, x = -2.

Make COS the subject of the formula

docker41 [41]

c^2 = a^2 + b^2 - 2(ab)(cos C)

c^2 + 2(ab)(cos C) = a^2 + b^2

2(ab)(cos C) = a^2 + b^2 - c^2

cos C = (a^2 + b^2 - c^2) / 2ab - Answer choice E

Hope this helps! :)
