Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros. write the polynomial in standard form. 2,5-i

Hence, the polynomial function in standard form is:

Step-by-step explanation:

We are given a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros 2,5-i.

As we know that the polynomial function has rational coefficients.

so any complex root always appear in pair.

so as 5-i is a root of f(x) then it's complex conjugate 5+i is also an root of f(x).

Hence f(x) could be represented as:  

Hence, the polynomial function in standard form is:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
