Answer:

Step-by-step explanation:
Assuming that the function is

First, we need to remove the parenthesis. Once this is done, we get

Now that the parenthesis are gone, we can differentiate each term. To do this, we can use the power rule, which states

This gives us

That would be choice 3
middle term = -3mn-8mn = -11mn and last term = + 2n^2
9514 1404 393
Answer:
11
Step-by-step explanation:
The future value of the account is given by the formula ...
A = P(1 +r/12)^(12t) . . . . principal P invested at rate r for t years
Solving for t, we find ...
A/P = (1 +r/12)^(12t) . . . . . . . . . . . divide by P
log(A/P) = 12t·log(1 +r/12) . . . . . . take logs
Divide by the coefficient of t, then fill in the numbers.
t = log(A/P)/(12·log(1 +r/12)) = log(202800/93000)/(12·log(1 +.068/12))
t ≈ 11.497
It will take about 11 years for the account balance to reach the desired amount.
The answer is D
i plugged in all the equations and the equation for D is the one that works
