We have been given a function
. We are asked to find the amplitude, period and phase shift of the function
We can see that our given function is in form
, where,
= Amplitude.
Period = 
C = Horizontal shift,
D = Vertical shift.
We can see that value of a is 1, therefore, the amplitude of given function would be 1.
We can see that B is equal to 8, so we will get:

Therefore, the period of given function is
.
Since the value of C is 1, therefore, horizontal shift is 1.
Since the value of D is 2, therefore, vertical shift would be 2.
<span>V = 1/3(3.14)r^2h
=1.046r^2h
Solving for V </span>
We know that
<span>Joey and Rita paint a room in 8 hours
so
100%----------> 8 hours
X%----------> 1 hour
x=100/8-----> 12.5%
that means
</span>Joey and Rita paint 12.5% of a room in 1 hour
Billy paint a room in 12 hours
so
100%----------> 12 hours
X %------------> 1 hour
x=100/12----> x=8.33 %
that means
Billy paint 8.33% of a room in 1 hour
i<span>f all three work together
then
All three paint (12.5%+8.33%) in 1 hour
20.83%------------> 1 hour
100%------------> x
x=100/20.83-----> x=4.8 hours
the answer is
4.8 hours</span>
The simple interest formula is A = P(1+rt) where P is your principal, or your initial amount, r is your rate and t is your time. Substitute the knowns into the equation.We get:
A = 100(1+0.15*15) = 325
