Answer:
The time required is about 75 years 3 months
Step-by-step explanation:
We know that the simple interest is expressed as
A = P (1 + rt)
A = final amount =$8200
P = initial principal
: balance=$200
r = annual interest rate 7.75%
7.75/100= 0.0775
t = time (in years)
Substituting our data into the expression we have
8200= 1200(1+0.0775*t)
8200=1200+93t
93t= 8200-1200
93t= 7000
t= 75.27
The time required to get a total amount, principal plus interest, of $8,200.00 from simple interest on a principal of $1,200.00 at an interest rate of 7.75% per year is 75.27 years (about 75 years 3 months)
Parameterize the surface

by


with

and

, which has surface element

Then the surface integral becomes
Answer:
C. -0.68427
Step-by-step explanation:
Enter the data into a graphing calculator.
First decide which is the independent and which is the dependent variable. Since the value of the stock depends on the day, value will be dependent and day will be independent.
This means that the days will be entered into the first list and the values will be entered into the second list.
Entering these and running the linear regression, we find the r-value to be -0.68427
