A recipe for apple sause calls for 1/3 cup of honey. The recipe makes 8 servings. How many cups of honey are needed to make 20 s

Komok [63]

To make exactly 20 servings, we need to know how much honey is used for exactly one serving.
Given that 1/3 cup of honey equates to 8 servings, divide 1/3 by 8 to get the amount of honey needed for 1 serving.
Then, to figure out how much honey is needed for 20 servings, simply multiply that result by 20.

Find a polynomial function of lowest degree with rational coefficients

xxMikexx [17]

Since -5i is a zero, then its complex conjugate +5i is also a zero of the function.

Therefore,

x + 5i, x - 5i , and x - 3 are factors of the polynomial.

Hence, the polynomial function, P(x), of the lowest degree with rational coefficients is given by

$P(x)=(x+5i)(x-5i)(x-3)$

Which implies that

$\begin{gathered} P(x)=(x^2-(5i)^2)(x-3)=(x^2-25i^2)(x-3) \\ \text{ Since i}^2=-1,\text{ then we have} \\ P(x)=(x-3)((x^2+25)=x^3+25x-3x^2-75 \end{gathered}$

Hence the polynomial is
