Suppose that the average adult in the United States will work x number of days (rounded to the nearest day) to earn enough to pay for all of the household's leisure activities in that year. This number can be calculated by multiplying the average percent of household income spent on leisure activities by 365 (the number of days in a year). The bar graph shows the percent of income spent in various countries of the world. Use the graph to answer the question.
List all countries in the graph in which less than 12% of household income is spent, on average, for leisure activities.
A. China, Australia, France B. Germany, Britain, Japan, USA C. China, Australia, France, Germany D. China, Australia
Solve the problem.The temperature (in degrees Fahrenheit) of a dead body that has been cooling in a room set at 70° is measured as 88°. One hour later, the body temperature is 87.5°. How long (to the nearest hour) before the first measurement was the time of death, assuming that the body temperature of the deceased at the time of death was 98.6°. Assume the cooling follows Newton's Law of Cooling: U = T + (Uo - T)ekt.

Match the graph with the correct equation.
A. y = sin 2x cos (-2) - cos 2x sin (-2) B. y = cos 2x cos (-2) + sin 2x sin (-2) C. y = cos 2x cos (-2) - sin 2x sin (-2) D. y = sin 2x cos (-2) + cos 2x sin (-2)
