Hello I need some help! Set a system of linear equations ( maybe 3 variables) for this problem. A nutritionist wants one of his patients to eat a meal with 66 grams of protein, 94.5 grams of carbohydrates and 910 milligrams of calcium. The food service of the hospital informs the nutritionist that the meal of the day is chicken, corn grains and 2% milk. Each serving of chicken has 30 grams of protein, 35 grams of carbohydrates and 200 milligrams of calcium. Each serving of corn has 3 grams of protein, 16 grams of carbohydrates and 10 milligrams of calcium. Each serving of 2% milk has 9 grams of protein, 13 grams of carbohydrates and 300 milligrams of calcium. How many servings of each food should be served to the patient?

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 0 a. at what time does the particle reverse direction? b. when is the displacement positive? (round one decimal place and answer in interval notation) c. when is the displacement negative? (round one decimal place and answer in interval notation) d. when is the particle’s acceleration positive? (round one decimal place and answer in interval notation) e. when is the particle’s acceleration negative? (round one decimal place and answer in interval notation)

The school track has eight lanes. each lane is 1.25 meters wide. the arc at each end of the track is 180. the distance of the home straight and the radii for the arcs in the 1st 4 lanes are given. s=85m r1=36.5m r2=37.75m r3=39m r4=40.25m part one: find the radii of lanes 5 through 8 of the track. show your work. part two: if max ran around lane one, how far did he run? show your work and explain your solution. part three: max wants to run a total of three laps around the track, choose two additional lanes (2-8) for him to run and find the distance around those two lanes. show your work and round to the hundredths. part 4: based on your lane choices in part three, what was the total distance max ran in the three laps around the track?
