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:
4 pi
Step-by-step explanation:
diameter = 2r
4 =2r
r =2
area = pi × (r)^2
= pi × 2^2
= 4 pi
Take 6.8 and divide by 2.72 and you get 2.5 hours
Answer:
for 7 its b and for 8 its C becuase i took this test and got it right
Step-by-step explanation:
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
