    The Malthusian and Logistic Models of Population Growth

    Please see the attached file. This is one question but broken in parts. Formula for Malthusian Model: dP/dt = r*P Formula for Logistic Model: dP/dt=rP(1-P/K) PS> I Prefer hand written work showing the steps if it is neat. It's up to you..I just have a hard time reading fractions & exponents in a word document etc.

    In what ways can the cycle of inequality be broken in schools?

    Savage Inequalities is a wonderful book to reference here as it does point to the problem of inequitable funding. In other words the poor stay poor because the school is funded disproportionally from community to community. This then impacts society's views of certain minorities and the poor, but then it also continues to fuel t
