License plates in a particular state display 4 letters followed by 2 numbers. How many different license plates can be manufactured for this state? There are \( \square \) different license plates that can be manufactured for this state. (Simplify your answer. Type an integer or a fraction.)

The half-life of radium is 1690 years. If 60 grams are present now, how much will be present in 430 years? \( \square \) grams (Do not round until the final answer. Then round to the nearest thousandth as needed.)

\#5. The ratio of pink roses to yellow roses in a flower arrangement is \( 5: 3 \). If there are 15 yellow roses, then how many total flowers are in the arrangement?

What function is the reflection of \( f(x)=|x+2| \) about the \( x \)-axis? \( g(x)=|x-2| \) Non of the other options \( g(x)=|-x+2| \) \( g(x)=-|x-2| \)

Simplify \( \frac{8}{\sqrt{6}+2} \)

The half-life of radium is 1690 years. If 40 grams are present now, how much will be present in 860 years? \( \square \) grams (Do not round until the final answer. Then round to the nearest thousandth as needed.)
