To find the sum of \( x^{3}+4 x-5 \) and \( 13 x^{2}+x-6 \), we simply add the corresponding terms: 1. For \( x^{3} \), we have \( 1x^{3} + 0x^{3} = 1x^{3} \). 2. For \( x^{2} \), we have \( 0 + 13x^{2} = 13x^{2} \). 3. For \( x \), we have \( 4x + 1x = 5x \). 4. For the constant terms, we have \( -5 + (-6) = -11 \). Putting it all together, the sum is: \[ x^{3} + 13x^{2} + 5x - 11 \]

An animal breeder can buy four types of food for Vietnamese pot-bellied pigs. Each case of Brand A contains 25 units of fiber, 40 units of protein, and 40 units of fat. Each case of Brand B contains 100 units of fiber, 130 units of protein, and 110 units of fat. Each case of Brand C contains 275 units of fiber, 350 units of protein, and 310 units of fat. Each case of Brand D contains 200 units of fiber, 260 units of protein, and 200 units of fat. How many cases of each brand should the breeder mix together to obtain a food that provides 3975 units of fiber, 5100 units of protein, and 4440 units of fat? Let x represent the number of cases of Brand A, y represent the number of cases of Brand B, z represent the number of cases of Brand C, and w represent be the number of cases of Brand D. There are four ways in which the breeder can mix brands to obtain a food that provides 3975 units of fiber, 5100 units of protein, and 4440 units of fat. If \( w=0 \), the solution is \( (\square, \square, \square, 0) \).

An investor plans to put a total of \( \$ 110,000 \) in a money market account, a bond fund, an international stock fund, and a domestic stock fund. She wants \( 60 \% \) of her investment to be conservative (money market and bonds). The investor wants the amount in international stocks to be one-fourth the amount in domestic stocks. Finally, the investor needs an annual return of \( \$ 4,400 \). Assuming the investor gets annual returns of \( 2.5 \% \) on the money market account, \( 3.5 \% \) on the bond fund, \( 4 \% \) on the international stock fund, and \( 6 \% \) on the domestic stock fund, how much should the investor put in each investment? The investor should put \( \$ 8800 \) in the international stock fund. (Type a whole number.) The investor should put \( \$ \square \) in domestic stock fund. (Type a whole number.)
