Choose the best description of the transit method of locating exoplanets. A When a planet passes between a star and an observer the luminosity of the star is reduced by a small amount.
B Using satellite based telescopes in different locations astronomers are able use parallax calculations to determine if there are planets in orbit around a star.
C Using a telescope, wobble can be detected from the effect that the planet's gravity has on the star.
C By aiming powerful telescopes directly at star systems astronomers are able to detect larger planets.

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
