x = 
is the restricted value
the denominator of the fraction cannot be zero as this would make it undefined.
Equating the denominator to zero and solving gives the value that x cannot be
solve : 8x - 2 = 0 → 8x = 2 → x =
Answer;
= $ 3623.85
Explanation;
To calculate compound interest we use the formula;
FV = OV( 1 + r/100)^n
FV=Future value which is what the value will be after the interest is calculated, this is what you are looking for.
OV=Original value, the amount of money you started with, in this case
3000
r=interest rate, in this case its 6.5
n=years its being compounded annually, in this case 3
= 3000(1 + 6.5/100)^3
= 3623.848875
≈ 3623.85
I think it’s 5. I’m not sure
Hello from MrBillDoesMath!
Answer:
x = 4
x = ( -7 + sqrt(29)) /2
x = ( -7 - sqrt(29)) /2
Discussion:
x^3+3x^2-23x-20 factors as (x - 4) (x^2 + 7 x + 5) so x =4 is one root
The roots of the quadratic factor, x^2 + 7x + 5, can be found using the quadratic formula where a = 1, b = 7, and c = 5
x = ( -b +\- sqrt(b^2-4ac)) / 2a
x = ( -7 +\- sqrt( 7^2 - 4*1*5) ) / (2*1) =>
x = ( -7 +\- sqrt (49-20) ) / 2 =>
The "+" root: ( -7 + sqrt(29)) /2
The "-" root: ( -7 - sqrt(29)) /2
