Answer:
The expression that calculates the speed in meters per second of an object that travels a distance of 100 m every 20 s is 
Step-by-step explanation:
We are given:
Distance = 100 m
Time = 20 s
We need to find:
Speed
The formula used is: 
Putting values and finding the expression

So, the expression that calculates the speed in meters per second of an object that travels a distance of 100 m every 20 s is 
<em>Note: Kindly recheck your options, As option B is not written correctly.</em>
Based on the entries into the TVM solver, the expression that will return the same value for PV is
.
<h3>Which formula will give the same Present Value?</h3>
The formula for present value for this series of cashflows is:
= 
Based on the P/Y and the C/Y being 12, the number of periods given in the graphing calculator will be the same in the formula, which is 108 periods.
The interest rate of 6.6% will also be the same in the formula.
The best option is therefore <u>option B </u>which has all these figures and so will give the same present value.

x = A cos ω t
where,
A is the amplitude
ω is the angular frequency
Since the shape is a circle, therefore the amplitude is
simply equal to 2π or 6.28 rad while the angular frequency is 5 rad/s, therefore:
x = 2π cos 5 t
