Answer:

2w2-5w-11 just subtract the second set of numbers from the first but it has to be like terms such as anything that is squared would only be applicable to another term with that is squared. a term is any group of number separated by a plus or a minus but it is not a term if it is separated by a multiplication symbol or a division symbol

Two forces, one of 45 pounds and the other 50 pounds, act on the same object. The angle between the forces is 33°. Find the magn

bearhunter [10]

Answer:

The magnitude of the resultant force is: 27.40 pounds

Step-by-step explanation:

Given

$F_1 = 45$

$F_2 = 50$

$\theta = 33$

Required

The magnitude of the resultant vector

To do this, we apply cosine formula

$R^2 = F_1^2 + F_2^2 - 2 * F_1 * F_2 * \cos(\theta)$

This gives:

$R^2 = 45^2 + 50^2 - 2 * 45 * 50 * \cos(33)$

$R^2 = 2025+ 2500 - 4500* 0.8387$

$R^2 = 2025+ 2500 - 3774.15$

$R^2 = 750.85$

Take square roots of both sides

$R = \sqrt{750.85\\$

$R = 27.40$
