Option B: 
is the correct answer.
Explanation:
The exponential equation is 
If 
, then 
Thus, the equation becomes
Applying log rule, 
and thus the equation becomes
Since, we know that, 
, using this we get,
Hence, the logarithmic equation which is equivalent to the exponential equation is
Thus, Option B is the correct answer.
Answer:
3 years -> value decreases by 20% 3 times
20% -> value is 80% of the original price
1st year value (after 20% decrease) = S15,500×
= S12,400
2nd year value (after 20% decrease) = S12,400×
= S9,920
3rd year value (after 20% decrease) = S9,920×
= S7,936
Answer:
∠ KLJ = 70°
Step-by-step explanation:
The segment KL joins the midpoints of 2 sides of the triangle and is therefore parallel to the third side HG , then
∠ KLJ and ∠ HGL are corresponding angles and are congruent , so
∠ KLJ = 70°
