Answer:
The formula to get the rate R would be:
principal x (1+R)^time = (principle + interest)
=> 3890 x (1 + R)^4 = 5908
=> (1 + R)^4 = 5908/3890
=> (1 + R)^4 = 1.5188
=> 1 + R = 1.11
=> R = 1.11 - 1 = 0.11 = 11%

Step-by-step explanation:
72/144 = 3/6
I'm not 100% sure, but I'm pretty sure its 11 and 13
Answer:
Step-by-step explanation:
We are given 
, 
and 
are zeros of the function. We can use the sum and product of roots. You may have come across these equations before ↓
Since the coefficients are already in a, b, and c's, we do not need to sub in anything else.
Now, you are asked to evaluate 
. The next step after finding the roots above ↑, is to factorise this equation to be solved.
= 
Sub in each respective roots,
= 
=
