Answer:
Option D
Step-by-step explanation:
To calculate compound interest we will use the formula :
Where,
A = Amount on maturity
P = Principal amount = $3000
r = rate of interest = 8.4% = 0.084
n = number of compounding period = Monthly = 12
t = time = 1 year
Now put the values in the formula.
= 
= 3000(1.007)¹²
= 3000 × 1.08731066
= 3261.93198 ≈ $3261.93
While the other bank compounds interest daily.
Therefore, n = 365
Now put the values in the formula with n = 365
= 3000 × 1.08761958
= 3262.85874 ≈ $3262.86
Difference in the ending balance = 3262.86 - 3261.93
= $0.93
The difference in the ending balances of both CDs after one year would be $0.93.
Answer:V= 1526.8m3
Step-by-step explanation: pi (9)2(6)
For a quadratic of the form
, we have the quadratic formula
,
where a is the coefficient (number before the variable) of the squared term, b is the coefficient of the linear term, and c is the constant term.
So, given
, we can get that
, and
. We substitute these numbers into the quadratic formula above.
This is our final answer.
If you've never seen the quadratic formula, you can derive it by completing the square for the general form of a quadratic. Note that the
symbol (read: plus or minus) represents the two possible distinct solutions, except for zero under the radical, which gives only one solution.
Range is the highest value minus the lowest value
