Explanation:
Given
--- Ken's share
Required
The fraction each got
Since they both shared a cake, we have:
Substitute:
Factorize
Divide both sides by 3
Recall that:
Answer:
The image is formed at 0.44 m in front of the mirror
magnification (M) = 0.44
Explanation:
Applying, mirror formular
1/f = (1/u)+(1/v).................... Equation 1
Where f = Focal length of the convex mirror, u = object distance, v = image distance.
Using the real is positive convection,
From the question,
Given: f = -1.6/2 = -0.8 m( The focal length of a convex mirror is vitual), u = 1.0 m
Substitute these values into equation 1
-1/0.8 = (1/v)+(1/1)
Solve for v
1/v = 1.25+1
1/v = 2.25
v = 1/2.25
v = 0.44 m
Hence the image is formed at 0.44 m in front of the mirror
Magnification (M) = v/u
m = 0.44/1
m = 0.44
The first step in problem solving is of
course, identifying the problem. How could you solve the problem if there is no
problem in the first place? When one gets to identify the problem, the next
step is gathering of information to know more about the problem. One needs to
get to know and examine the pros – the benefits – and con – the flaws – of the
problem well. After doing all the needed data gathering and possibly,
experimentation, when can start looking for the possible solutions of the
problem.
