Answer:

2.22%
Step-by-step explanation:
$8400 is invested in an account earning 2.2% interest (APR), compounded monthly.
So, the value of the account after t years will be given by
{Rounded to the four decimal places} (Answer)
Now, for t = 1 year, f(1) = $8586.67
So, the percentage of growth per year (APY) =
% {Rounded to the nearest hundredth of percent} (Answer)
Answer: f(2) = 6
Step-by-step explanation: In this problem, we are given the function
f (x) = (x + 1) 2 and we are asked to find f(2). In other words, if we put an "x" into our function, we get a (x + 1) 2 out.
f we put a 2 into the function, we get f(2) = (2 + 1) 2 out. Now all we have to do is simplify on the right side.
2 + 1 gives us 3 and if we multiply 3 by 2, we get a product of 6.
Therefore, f(2) is 6.

Sorry that's all i know

Although x ² and x both have the variable x, you can’t add them together. So x + x + x + x is 4x and we just leave x ² the same. So the simplified expression is x ² + 4x. I hope this helped!!
