Answer:
My payment for the 7th study session will be 78125 dimes.
Step-by-step explanation:
My friend will pay me 5 dimes for helping him study for the first time.
Now, I agree to help him if he multiplies my payment by 5 for each study session.
So, he will pay 25 dimes for the 2nd study session, 125 dimes for the 3rd study session and so on.
Hence, my payment in each study session increases in geometric progression as follows:
5, 25, 125, ........ so on.
So, the 7th term of this series indicates the number of dimes that my friend pays me after the 7th study session.
This is a G.P. series having first term 5 and common ratio 5, then the 7th term will be 
Therefore, my payment for the 7th study session will be 78125 dimes. (Answer)
Question:
Complete question for this is to find the equation for this and may be the graph.
Explanation:
As for the oscillation motion, initially peak is occurring hence it will be a cosine function with peak value of 3(cm).
To calculate time period, the whole cycle should be 360°
i.e.
cos (Xπ.t) = cos (360)
as the cycle completes at 1.2 sec hence by putting t=1.2, answer should be 360.
i.e.
X*180*t=360
X*180*1.2=360
X=5/3
So, the required equation is
Graph for this equation is attached here with this answer.
In graph,
x-axis: t=0 ~ t=1.2
y-axis: f(x)=-4 ~ f(x)=4
First, you need to turn it into a fraction by doing the multiplication. 6/1 × 3/20 which is 18/20. then you simplify it to get 9/10. 9/10 is your answer
