Sound travels fastest in ice because energy is easier to
transfer when the molecules are close together.
Sound travels slowest in steam because the sound has
to move around the gas molecules that are far apart.
Sound travels fastest in ice because the temperature of
solids is always greater, so the heat transfers the sound
energy
Sound travels slowest in steam because the pressure is
so great the sound cannot travel though the steam
particles

If the measure of xyz is 81 what is the measure of yz

Find the center and the radius of the circle with the equation: x^2-2x+y^2+4y+1=0?

After a dreary day of rain, the sun peeks through the clouds and a rainbow forms. you notice the rainbow is the shape of a parabola. the equation for this parabola is y = -x2 + 36. graph of a parabola opening down at the vertex 0 comma 36 crossing the x–axis at negative 6 comma 0 and 6 comma 0. in the distance, an airplane is taking off. as it ascends during take-off, it makes a slanted line that cuts through the rainbow at two points. create a table of at least four values for the function that includes two points of intersection between the airplane and the rainbow. analyze the two functions. answer the following reflection questions in complete sentences. what is the domain and range of the rainbow? explain what the domain and range represent. do all of the values make sense in this situation? why or why not? what are the x- and y-intercepts of the rainbow? explain what each intercept represents. is the linear function you created with your table positive or negative? explain. what are the solutions or solution to the system of equations created? explain what it or they represent. create your own piecewise function with at least two functions. explain, using complete sentences, the steps for graphing the function. graph the function by hand or using a graphing software of your choice (remember to submit the graph).
