23 where x represents the number of years since 1974 and f (x) represents the amount of cholesterol consumed each day per person. How many milligrams per person is consumed in 1982? C) An object is thrown upward. Its height after t seconds is given by h(t) = 32t - 16t2 where the height is given in feet. At what time will object hit the ground? D) The weight (in grams) of a human brain during the last trimester of gestation and the first two years after birth can be approximated by function w(x) = x3 - 1500 where x is circumference of the head in cm. What is the approximate 100 x weight of brains with a circumference of 30 cm? If an infant brain weights 700 g, what is the circumference of the head?
