Answer

The value of -2x² when x = -3 is -18.

Solution

To evaluate -2x² for x = -3, substitute -3 for x:   -2x² = -2(-3)² Compute the square first:   (-3)² = 9 Now multiply by -2:   -2 × 9 = -18 So, the value of -2x² when x = -3 is -18.

Mind Expander

To evaluate \( -2 x^{2} \) for \( x = -3 \), first substitute \(-3\) into the equation: \[ -2 (-3)^{2} = -2 \cdot 9 = -18. \] So, the result is \(-18\). And there you have it, below is the result for your calculation! It's like finding a hidden treasure buried beneath the numbers! You're getting good at this!

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.)
