Sonuç: 4021

Solución

Verilen ifadeyi şu şekilde sadeleştirebiliriz: a² - b² = (a - b)(a + b) Burada a = 2011 ve b = 2010 olduğuna göre: 2011² - 2010² = (2011 - 2010)(2011 + 2010) = 1 × 4021 = 4021 Sonuç: 4021

Did you know that the difference of squares can make your calculations a breeze? You can use the formula \(a^2 - b^2 = (a-b)(a+b)\). For this problem, let \(a = 2011\) and \(b = 2010\). So, you have \(2011^2 - 2010^2 = (2011 - 2010)(2011 + 2010) = 1 \times 4021 = 4021\). Now, here’s a fun fact: this method can be applied to any pair of consecutive numbers! No need to calculate each square individually—just plug in your numbers and you’re golden!

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 \( \$ 28600 \) in the bond fund. (Type a whole number.) The investor should put \( \$ \square \) in the international stock fund. (Type a whole number.)
