<h3>
Answer:</h3>
The real solutions are -5, -4, 4, 5. There are no complex solutions.
<h3>
Step-by-step explanation:</h3>
The equation ...
... x^4 -41x^2 +400 = 0
can be factored as ...
... (x^2 -16)(x^2 -25) = 0
... (x -4)(x +4)(x -5)(x +5) = 0
So, all roots are real and are ...
... x ∈ {-5, -4, 4, 5}
_____
These are the values of x that make the factors zero.
Answer:
the second i think i dont know for sure

Hi,
By definition, interest rate is <span>the proportion of a loan that is charged as interest to the borrower, typically expressed as an annual percentage of the loan outstanding.
To find interest rate you need the principle, interest earned, and time.
</span><span>
Solve for Rate (R)
</span><span>Where: r = I / Pt
</span>
I = 837 (dollars)
P = 3100 (dollars)
t = 6 (years)
r = 837 / ( 3100 × 6 ) = 0.045
<span>r = 0.045
</span>
*converting r decimal to a percentage
R = 0.045 * 100 = 4.5%/year*
The interest rate required to accumulate simple interest of $ 837.00 from a principal of $ 3,100.00 <span>over 6 years is 4.5% per year.
</span>
In short, rate: 4.5% / year
