The bar graph shows the estimated number of calories per day needed to maintain energy balance for various gender and age groups for moderately active lifestyles. (Moderately active means a lifestyle that includes physical activity equivalent to walking 1.5 to 3 miles per day at 3 to 4 miles per hour, in addition to the light physical activity associated with typical day-to-day life.) a. The mathematical model $$W=-66 x^{2}+526 x+1030$$ describes the number of calories needed per day, W, by women in age group x with moderately active lifestyles. According to the model, how many calories per day are needed by women between the ages of 19 and 30, inclusive, with this lifestyle? Does this underestimate or The mathematical model The mathematical model $$M=-120 x^{2}+998 x+590$$ describes the number of calories needed per day, M, by men in age group x with moderately active lifestyles. According to the model, how many calories per day are needed by men between the ages of 19 and 30, inclusive, with this lifestyle? Does this underestimate or overestimate the number shown by the graph? By how much? c. Write a simplified rational expression that describes the ratio of the number of calories needed per day by women in age group $x$ to the number of calories needed per day by men in age group $x$ for people with moderately active lifestyles.
