Answer: 879
Step-by-step explanation:
The order of operations calls for Parenthesis, Multiply, Divide, Add, Subtract. From left to right.
So we do the parenthesis first (102 - 4)
-3 + 9 (98)
Next we multiply 9 and 98
-3 + 882
Lastly we add -3 and 882
879
Answer:
n = 3 + i√11 , 3 - i√11
Step-by-step explanation:
This is a quadratic equation and the first step is to write it in standard form:
5n^2 - 30n + 100 = 0
Divide through by 5:
n^2 - 6n + 20 = 0
Completing the square:-
(n - 3)^2 - 9 + 20 = 0
(n - 3)^2 = -11
n - 3 = i√11 or - i√11
n = 3 + i√11 , 3 - i√11
(2 complex roots).
To reach $3,900 with an interest rate of four percent on an account originally containing $1,100, it would take 32.27 years.
Hope this helps you
Isn't it n÷2. Cause you are diving the number by 2
The correct estimate would be 36 b/c the answer is actually 35.91656999213594
