Sure, let's evaluate the expression (-v+4)/(4*v) for v=0.4.
Step 1: Substitute 0.4 for v in the equation, we have
(-0.4+4)/(4*0.4)
Step 2: Then we simplify the operation inside parentheses in both the numerator and the denominator.
In the numerator, -0.4+4 results in 3.6.
In the denominator, 4*0.4 results in 1.6.
So now our equation is: 3.6/1.6
Step 3: Finally, we divide 3.6 by 1.6 to solve the equation, and we get
3.6 / 1.6 = 2.25
So, the solution to (-v+4)/(4v) for v=0.4 is 2.25.
