Answer:
an = (1 + 2·(n - 1))/2^(n - 1) = 2^(1 - n)·(2·n - 1)
sn = 6 - 2·0.5^n·(2·n + 3)
None, because 4/5 > 4/9. Check to ensure that you have copied down this problem correctly.
Answer:
the account won't yield the same amount despite the same principal amount.
Step-by-step explanation:
To test this assertion :
Let principal = $1000
t = 1 year
Compound interest formula :
A = P(1 + r/n)^nt
P = principal ; r = rate, n = number of times interest is compounded per period ; t = time
Account A :
Rate = 4% annually
A = 1000(1 + 0.04/1)^1
A = 1000 * 1.04 = $1040
Account B:
Rate = 2% compounded semianually ; n = 12 /6 = 2
A = 1000(1 + 0.02/2)^1*2
A = 1000(1.01)^2
A = 1000 * 1.0201
A = $1020.1
From the result, the account won't yield the same amount despite the same principal amount.
Answer:
14
Step-by-step explanation:
-3(2)+4(5) multiply -3 and 2 then multiply 4 and 5
-6+20= add -6 to 20
14
If you're trying to simplify, use distributive property. You can't multiply 6y by 2/3x or 6k, so multiply 6y by 1/2 to get 3y. So, the simplified expression would be (2/3x+6k-3y)
