Answer:
1/(3x) =(x -2)/(4x^2 +9)
Step-by-step explanation:
The denominator cannot be factored further, so the final form will be ...
A/(3x) + (Bx +C)/(4x^2 +9)
The value of this is ...
(A(4x^2 +9) +(3x)(Bx +C))/(3x(4x^2 +9))
= ((3B+4A)x^2 +3Cx +9A)/(3x(4x^2 +9))
Equating coefficients gives ...
3B+4A = 7
3C = -6 ⇒ C = -2
9A = 9 ⇒ A = 1
Using the found value of A, we find ...
3B +4 = 7 ⇒ B = 1
Then the decomposition is ...
Answer:
<h3>The answer is 5.7 %</h3>Step-by-step explanation:
To find the rate given the principal , time and interest , we use the formula
where
p is the principal
t is the time
I is the interest
From the question
Principal = $1,250
Time = 4 years
Interest = $285
We have
We have the final answer as
<h3>5.7 %</h3>Hope this helps you
