087 The brain mass of a fetus can be estimated using the total mass of the fetus by the function b = 0.22m ,where m is the mass of the fetus (in grams) and b is the brain mass (in grams). Suppose dm the brain mass of a 27-9 fetus is changing at a rate of 0.24 g per day. Use this to estimate the rate of change of the total mass of the fetus, F' dm dt (Round to ve decimal places as needed.) = g per day 1 Sociologists have found that crime rates are inuenced by temperature. In a town of 100,000 people, the crime rate has been approximated as C = EU 65)2 + 100, where C is the number of crimes per month and T is the average monthly temperature in degrees Fahrenheit. The average temperature for May was 78 and by the end of May the temperature was rising at the rate of 6 per month. How fast is the crime rate rising at the end of May? At the end of May, the crime rate is rising by crime(s) per month. (Simplify your answer.) An ice cube that is 9 cm on each side is melting at a rate of 4 cm3 per minute. How fast is the length of the side decreasing? E> At the moment when the ice cube is 9 cm on each side, the side length is decreasing at a rate of approximately D cm per minute. (Type an integer or decimal rounded to three decimal places as needed.)
