There are two ways you can easily identify concave polygons: they have at least one internal angle that is bigger than \( 180^{\circ} \). They also have at least one diagonal that lies outside the polygon. In convex polygons, on the other hand, all internal angles are less than 180 and all diagonals lie

Use properties of logarithms to find the exact value of the expression. Do not use a calculator. \( \log _{12} 3+\log _{12} 4 \) \( \log _{12} 3+\log _{12} 4=\square \) (Type an integer or a simplified fraction.)

Resolver: Un Padre ha dejado una herencia de \( \$ 5.000 .000 \) para repartir a sus hijos de manera inversamente proporcional a sus edades: 10,12 y 18 años respectivamente. a) Cuanto le corresponde a cada uno? b) Si hubiera dejado \( \$ 3.000 .000 \), cuánto le corresponde a cada hijo? c) Si hubiera dejado \( \$ 12.000 .000 \), cuánto le corresponde a cada hyo?

\( g(x)=\sqrt{2-x} \) lassify the given function as a polynomial function, rational function, or root fur

What best describes a portfolio? Purchasing a 10 -year CD from your bank with a \( 3 \% \) APY. An investor's collection of investments. Taking the car you bought for \( \$ 3,000 \) and selling it for \( \$ 4,000 \). Purchasing a share of ownership in Nike.

An unknown compound has the following chemical formula: \[ \operatorname{Cr}(\mathrm{OH})_{\mathrm{x}} \] where \( x \) stands for a whole number. Measurements also show that a certain sample of the unknown compound contains 7.90 mol of oxygen and 2.63 mol of chromium. Write the complete chemical formula for the unknown compound.
