X = 2 liter container
Y = 3 liter container
the total of containers are:
X + Y = 400
the capacity of the containers is
2X + 3Y = 1100
Assembling the equation system
2X + 3Y = 1100
X + Y = 400 x(-2)
2X + 3Y = 1100
<u>-2X -2Y = - 800 </u>
<h3>Y = 300</h3>
X + Y = 400 so
X + 300 = 400
X = 400 - 300
<h3>X = 100</h3>

<em>Observe que:</em>
<em>1 vasilha de 2L = 1 × 2 = 2L</em>
<em>2 vasilhas de 2L = 2 × 2 = 4L</em>
<em>3 vasilhas de 2L = 3 × 2 = 6L</em>
<em>X vasilhas de 2L = X × 2 = 2X litros</em>
<em>.....</em>
<em>1 vasilha de 3L = 1 × 3 = 2L</em>
<em>2 vasilhas de 3L = 2 × 3 = 4L</em>
<em>3 vasilhas de 3L = 3 × 3 = 6L</em>
<em>X vasilhas de 3L = X × 3 = 3X litros</em>
<em>Logo 2X + 3Y = 1100</em>
<em>Existem X e Y vasilhas que num total sao 400, logo</em>
<em>X + Y = 400</em>
Answer:
Step-by-step explanation:
<u>Given information</u>:
- Polynomial function with real coefficients.
- Zeros: 0, 2i and (3+i).
For any complex number , the complex conjugate of the number is defined as .
If f(z) is a polynomial with real coefficients, and z₁ is a root of f(z)=0, then its complex conjugate z₁* is also a root of f(z)=0.
Therefore, if f(x) is a polynomial with real coefficients, and 2i is a root of f(x)=0, then its complex conjugate -2i is also a root of f(x)=0.
Similarly, if (3+i) is a root of f(x)=0, then its complex conjugate (3-i) is also a root of f(x)=0.
Therefore, the polynomial in factored form is:
As we have not been given a leading coefficient, assume a = 1:
Expand the polynomial:
