Una recta atraviesa el punto \( (2,-9) \) y tiene una pendiente igual a -9 . Escribir una ecuación en la forma punto pendiente para esta recta.

Determine if the following is an example of descriptive or inferential statistics. 300 female Osprey hatch-lings were tracked until they died or succeeded in laying their own eggs. Based on the data, the researchers concluded that somewhere between \( 12 \% \) and \( 18 \% \) of all female Osprey hatch-lings in the US succeed in growing up to lay their own eggs.

Question 2 Simplify the following, giving your answer with positive exponents. (Assume all variables are \( \neq 0 \).) \( \frac{\left(2 a^{3} b^{-2}\right)^{3}}{2 b^{-2}} \div \frac{4 a^{6} b^{-3}}{2^{4} b^{2}} \)

A car was valued at \( \$ 45,000 \) in the year 1992 . The value depreciated to \( \$ 14,000 \) by the year 2003. A) What was the annual rate of change between 1992 and 2003 ? \( r= \) B) What is the correct answer to part A written in percentage form? \( r= \) C) Assume that the car value continues to drop by the same percentage. What will the value be in the year 4 decimal places. 2006 ? value \( =\$ \square \)

ily task 10.1: Classwork/Homework/Data-interpretation e the above of the electromagnetic spectrum to answer the following questions. Which type of EM radiation has the: Longest wavelength? Shortest wavelength? Highest energy? Lowest frequency? Give one word for each of the following descriptions. The type of radiation that can travel through flesh, but not through bones. It therefore casts a shadow of bones. The type of radiation that causes the skin to become brown. Visible light with the longest wavelength. Use the wave equation \( v=\mathrm{f} \lambda \) to answer the following questions. Calculate the highest frequency that radio waves can have. Calculate the lowest frequency that gamma rays can have. ( \( 1 \mathrm{~nm}=1 \times 10^{-9} \mathrm{~m} \) ) What is the main difference between radio waves and gamma rays? Radio waves tend to move around objects, while gamma rays tend to move through objects. Give a possible explanation for this phenomenon. What frequencies of light are visible to the human eye? ( \( 1 \mathrm{~nm}=1 \times 10^{-9} \mathrm{~m} \) ) Calculate the highest energy associated with X rays.
