B makes the most sense. Try it out and let me know!!
Answer:
A = 1000 ( 1 + .031/12) ^(12t)
The approximate monthly interest rate is .2583 percent
Step-by-step explanation:
A=1000(1.031)^t
The formula for compound interest is given by
A = P(1 + r/n) ^ (nt)
Take 1.031 and subtract 1
.031 is the yearly rate in decimal form
A = 1000 ( 1 + .031/12) ^(12t)
Change to a percent = 3.1 %
Divide by 12
3.1/12 = .2583333333(repeating) %
This would be the monthly rate
For the answer to the question above, I'll provide a solution for my answer below.
x^4 - 41x^2 = - 400
<span>=> x^4 - 41x^2 + 400 = 0 </span>
<span>=> x^2 = (1/2) [41 ±√(1681 - 100)] </span>
<span>=> x^2 = (1/2) (41 ± 9) </span>
<span>=> x^2 = 16 or 25
</span>
So, therefore, the answers for your problem are
<span>=> x = ± 4 or ± 5.
I hope my answer helped you. </span>
