Ultrasound is often used to make images of developing fetuses. In particular, by measuring the size of a fetus ultrasound technicians can estimate its age and then predict its b..chdate. To do this requires formulas for fetus size as a function of age. Verburg et al. (2008) fit data from over 6000 fetal ultrasounds. They measured the femur length, L, (in mm) as a function of the fetus age,t, (in weeks) and found the following formula: L = -37.50 +3.71t - 0.000633+³ Calculated when t = 20. b. Does the rate of growth of the fetus increase or decrease as it ages? O A. Increases and decreases O B. Increases O C. Not enough information to tell ➜ D. Decreases
