With U.S. Census Bureau data (actual and projected) for selected years from 1960 to 2050, the rate of change of U.S. population P can be modeled by dp--0.0002187t2 0.0276t + 1.98 dt million people per year, where t 0 represents the year 1960. (a) During what year does this rate of change reach its maximum? (b) In 1960, the U.S. population was 181 million. Use this to find a model for P(t). (Enter exact numerical values. Do not round.) P(t)0.0000729r0.0138r +1.98t181 (c) For 2025, the Census Bureau's predicted U.S. population is 348 million. What population does the model predict? (Round your answer to the nearest million.) million
