Answer:
Principal = 3500
Time = 8 years
We are given that compound quarterly
So, No. of compounds per year = 2
Rate of interest = 5%
Formula :
Substitute the values :
Interest = 3863.345 - 3500 = 363.345
Hence the total amount in an investment of $3500 that was compounded quarterly for 8 years at a rate of 5% is $3863.345 and the interest that was made on that account mentioned is $363.345
Answer:
Mr. Mole is descending by 2.4 meters per minute
Step-by-step explanation:
Let
x ----> the time in minutes
y ---> the distance in meters
we know that
In this problem the rate of change or slope is the same that the speed
The formula to calculate the slope between two points is equal to
take two points from the table
(5,-18) and (8,-25.2)
substitute the values in the formula
---> is negative because is descending
