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

$R = \sqrt{750.85\\$

$R = 27.40$

A demand loan for $8,944.61 with interest at 7.8% compounded semi-annually is repaid after two years, seven months. What is the

disa [49]

Answer:

the correct answer is option D which is $1,954.94

Step-by-step explanation:

loan amount = $8,944.61

interest = 7.8% = 7.8 %/2 = 3.9 %

compounded semi annually = 2 × 12 + 7 = 31 months

time = 31/6 months

$I =P(1+\dfrac{r}{100})^{\frac{31}{6}}-P\\ \\I = 8994.61(1+\dfrac{3.9}{100})^{\frac{31}{6}}-8994.61 \\I =1954.94$

hence, the correct answer is option D which is $1,954.94
