Answer: $100,879.39
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = 18000
r = 9% = 9/100 = 0.09
n = 1 because it was compounded once in a year.
t = 20 years
Therefore,
A = 18000(1+0.09/1)^1 × 20
A = 18000(1.09)^20
A = $100,879.39
F'(x) = 7sec x . tan x - 5.
4x^2 - 2xy^2
5xy^2 +
3x^2y
_____________
12x^5y^4-2xy^2
This is so because 4+5+3 is 12, then using laws of indices to add your x and y you get x^5 and y^4
To simplify your answer to the lowest you have it in the form of
3x^2y^2(4x^2y - 2xy^2)
If you multiply this as well you get the same answer I got with the addition
