Two forces of 19.8 pounds and 36.5 pounds act on a body with an angle of 61.4 degrees between them. Choose the correct approximation for the magnitude of the resultant vector.

Based on your question Two forces of 19.8 pounds and 36.5 pounds act on a body with an angle of 61.4 degrees between them.

After setting up the vectors on the plane and doing the required math

The answer is 49.2 pounds

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
