Um estudante vai apresentar um projeto em sua escola sobre a concentração de renda no brasil e usará uma maquete para representar a pirâmide financeira brasileira, pintando cada classe nas faces laterais do sólido. em sua pesquisa, usou os dados da receita federal sobre o ano-calendário de 2014 fornecidos em 2016 para evidenciar a concentração de renda no país: dos declarantes do imposto de renda naquele ano, 28.433 pessoas – ou apenas 0,1% – ganham mais de 320 salários mínimos enquanto 21.480.006 (77,86%) ganham até 10 salários mínimos.

se sua pirâmide quadrangular regular terá 21 cm de altura e aresta da base igual a 20 raiz quadrada de 2 espaço cm e os 0,1% brasileiros ricos serão representados no topo da pirâmide, o comprimento da aresta lateral necessário para que o estudante represente a classe em perfeita proporção com a realidade é

a
2,1 cm.

b
2,3 cm.

c
2,5 cm.

d
2,7 cm.

e
2,9 cm.

The rate of decay of a radioactive substance depends upon the amount present initially. the mass y (mg) of the radioactive substance cobalt-60 present in a sample at time t (years) is represented by the exponential equation y=50e −0.1315 t . answer the following questions in complete sentences. 1. how does the exponential equation above compare to the equation for simple interest that is compounded continuously? explain the similarities. 2. what is the initial amount of cobalt-60 in the sample? 2. how much cobalt-60 is left after 8.4 years? show your work. 3. what would be the y-intercept of the graph? what does it represent? 4. after how many years will the amount of cobalt-60 left be 6.25 mg? explain what happens to the cobalt-60 after 50 years? 5. discuss some “real-world” examples and uses of cobalt-60
