Answer:

f(x) = 9x

Step-by-step explanation:

Given

The attached table

Required

Rule of the table

First, we calculate the slope(m)

m = \frac{y_2 -y_1}{x_2 - x_1}

Where

(x_1,y_1) = (0,0)

(x_2,y_2) = (3,27)

m = \frac{27 -0}{3 - 0}

m = \frac{27}{3}

m = 9

The table equation is:

y - y_1 = m(x - x_1)

So, we have:

y - 0 = 9(x - 0)

y - 0 = 9(x)

y= 9x

Hence:

f(x) = 9x

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
