Given:
Principal value = 40000
Rate of compounded interest = 20%
Time = 2 years
To find:
The interest.
Solution:
Formula for amount is
Where, P is principal, r is rate of interest and t is time in years.
Putting the given values, we get
Now, the formula for interest is
Therefore, the amount of compound interest is 17,600.
Answer:
Given the parent function:
Rule for Horizontal Stretches and Compression:
If parent function y=f(x), then y=f(cx) gives a horizontal stretch when c >1 and
a horizontal compression when 0<c<1.
therefore, by above definition
the function f(x) = is a Horizontal compression by a factor of
therefore, the function f(x) = is HORIZONTAL COMPRESSION of the parent function by a factor of 0.25
