Answer:
$27.50
Step-by-step explanation:
The amount of interest she will earn in a year is basically the initial amount multiplied by the rate of interest per year (in decimal).
We have to first convert 5 1/2% to decimal.
First,
1/2 means 0.5 (by dividing), so it becomes:
5.5%
Converting percentage to decimal is easy. We divide by 100, so we have:
5.5/100 = 0.055
Now we multiply:
500 * 0.055 = $27.5
So, in 1 year, Isabella earns an interest of $27.50
Answer:

if there are no x intercepts in a parabola, your discriminate is zero
Answer: 3x^3 -8*x^2 + 8*x + 3
Step-by-step explanation:
The standard form for a plolynomial is:
a*x^n + b*x^(n-1) + c*x^(n - 2) ........
We have:
(x-1)(3x^2-5x-3)
this is equal to:
3*x^3 - 5*x^2 + 3*x - 3*x^2 +5*x + 3
where the thing that i did is distribute the multiplication
this is equal to:
3x^3 -8*x^2 + 8*x + 3
I think that's true with 8
