Amagazine ran a survey about a web site for downloading music. readers could register their responses on the magazine's web site. identify what is wrong. choose the correct answer below. a. the sample is a census, so there is a good chance that the results do not reflect the population. b. the magazine has an interest in the survey results, so the source of the survey is questionable. c. the sample is a voluntary response sample, so there is a good chance that the results do not reflect the population. d. it is likely that the survey used a loaded question, so the results of the survey are not reliable.

If 1/√5+1/√5+1=p+q√r , find the values of p, q and r

Which exponential function has an initial value of 2? f(x) = 2(3x) f(x) = 3(2x)

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).
