Answer:
The answer to your problem is:
A. 6.4
B. -0.25
C. converging
Step-by-step explanation:
[ /Part A/ ]
We know that;
Then equals
6.4

[ /Part B/ ]
We can solve the problem which equals to:
$$ M = -
= -
Solve: -0.25
[ /Part C/ ]
In the problem we now that ‘ f ‘ is more less than ‘ o ‘ is converging.
Shown, since ‘ f ‘ > ‘ 0 ‘ lens is converging
Thus the answer to your problem is:
Part A. 6.4
Part B. -0.25
Part C. converging
