- World Military Expenditure The following chart shows total military and arms trade expenditure from 2011–2020 (t = 1 represents 2011). †A bar graph titled "World military expenditure" has a horizontal t-axis labeled "Year since 2010" and a vertical axis labeled "$ (billions)". The bar graph has 10 bars. Each bar is associated with a label and an approximate value as listed below. 1: 1,800 billion dollars 2: 1,775 billion dollars 3: 1,750 billion dollars 4: 1,730 billion dollars 5: 1,760 billion dollars 6: 1,760 billion dollars 7: 1,850 billion dollars 8: 1,900 billion dollars 9: 1,950 billion dollars 10: 1,980 billion dollars (a) If you want to model the expenditure figures with a function of the form f(t) = at2 + bt + c, would you expect the coefficient a to be positive or negative?

Use the appropriate formula to determine the percentage of marriagesending in divorce after 10 years when the wife is over 25 at the time ofmarriage.b. Use the appropriate line graph in Figure to determine the percentageof marriages ending in divorce after 10 years when the wife is over 25 at the time of marriage.c. Does the value given by the mathematical model underestimate or overestimate the actual percentage of marriages ending in divorce after10 years as shown by the graph? By how much?arrow_forwardPopulations of aphids and ladybugs are modeled by the equationsarrow_forward
