7. Find the angle between two forces acting on an object
of 55 pounds and 60 pounds given that the resultant
force is 103 pounds. Round to the nearest tenth. (Hint: write force 1 as a vector in the direction of the positive
x-axis and force 2 as a vector at an angle with the positive x-axis.)

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3
