The orbital speeds of asteroids and their distance from the sun are related. In the accompanying table, a represents orbital speed, in kilometers per second, and y
represents the distance from the sun, in millions of kilometers. Write a power
regression equation for this set of data, rounding all coefficients to the nearest ten-
thousandth. Using this equation, find the orbital speed, to the nearest tenth of a
kilometer per second, of an asteroid 278 million km from the sun.
