WILL GIVE BRAINLIEST BUT IT"S KIND OF A LONG QUESTION 3. The table shows the soil density of several soil samples at different depths.
Depth (m) 1 5 6 8 10 12 14 21 23 24 28
Soil density ( )
1045 1063 1102 1140 1191 1232 1249 1254 1265 1268 1273
(a) Write the quadratic regression equation that models the data. Let x = depth below the surface and let y = soil density.
(b) Use the equation to estimate the soil density of a sample at a depth of 26 m. Show your work.

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
