16. astronomers typically determine the distance to a galaxy
(a huge collection of billions of stars) by measuring the
distances to just a few stars within it and taking the mean
(average) of these distance measurements.

Given f(x) = 17-x^2what is the average rate of change in f(x) over the interval [1, 5]?

Which is a true statement comparing the graphs of x^2/6^2-y^2/8^2 = 1 and x^2/8^2-y^2/6^2 the foci of both graphs are the same points. the lengths of both transverse axes are the same. the directrices of = 1 are horizontal while the directrices of = 1 are vertical. the vertices of = 1 are on the y-axis while the vertices of = 1 are on the x-axis.
