Students in a marine biology program built underwater drones. The students were split into two groups, and each group designed and built its own drone. During a recent round of testing, they modeled the path of each drone using these
functions, where x is the horizontal distance from the launch site, in miles, and d(x) is the depth below the surface of the
water, in meters.
Voyager: d(2) = 0.25(x – 35)2 – 225
Pioneer: d(x) = 0.3(x – 32)2
- 270
Use the custom button to graph the functions and determine the depth of each drone at its lowest point.

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.

Sanya noticed that the temperature was falling at a steady rate of 1.4 degrees every hour from the time that she first checked her outdoor thermometer. by 6 a. m., the temperature had fallen 21 degrees. which expression can you use to find how many hours earlier she had first checked the thermometer?
