Use algebra to find the inverse of the function \( f(x)=6 x^{7}-6 \). The inverse function is \( f^{-1}(x)=\square \)

4. \( \left\{\begin{array}{l}x-3 y=-9 \\ 2 x+5 y=4\end{array}\right. \)

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.

A ferris wheel is 45 meters in diameter and boarded from a platform that is 2 meters above the ground. The six o'clock position on the ferris wheel is level with the loading platform. The wheel completes 1 full revolution in 4 minutes. The function \( h=f(t) \) gives your height in meters above the ground \( t \) minutes after the wheel begins to turn. What is the Amplitude? What is the Midline? \( y=\square \) meters What is the Period? How High are you off of the ground after 2 minutes?
