PLEASE HELP!!! WILL REWARD!! I need a written explanation (please do not just give me an answer!) The Oddville Academy offers three languages: Oriya, Dakhini, and Dutch (how odd!). Each student takes an odd number of languages – that is, every student takes either one language or three languages. Let x be the number of students taking Oriya, y be the number of students taking Dakhini, z be the number of students taking Dutch, and t be the number of students taking all three languages. Find an expression in terms of x, y, z, and t for the total number of students at the Oddville Academy.

The amount of medicine in his body f(t) after time t is shown by the equation below: f(t) = 300(0.88)t Which statement best describes the rate at which Henry's and Greg's bodies eliminated the medicine?choices:a. Henry's body eliminated the antibiotic faster than Greg's body.b. Henry's body eliminated the antibiotic at the same rate as Greg's body.c. Henry's body eliminated the antibiotic at half of the rate at which Greg's body eliminated the antibiotic.d. Henry's body eliminated the antibiotic at one-fourth of the rate at which Greg's body eliminated the antibiotic.

PLEASE HELP! LOTS OF POINTS!! WILL MARK BRAINLIESTThis is a set of questions about exponential growth. Do some research and find a city that has experienced population growth. Determine its population on January 1st of a certain year. Write an exponential function to represent the city’s population, y, based on the number of years that pass, x after a period of exponential growth. Describe the variables and numbers that you used in your equation.Find another city whose population starts larger than the city in part (a), but that during this same time experienced population decline. Determine its population for January 1st of the same year you picked for part (a). Write an exponential function to represent the city’s population, y, based on the number of years that pass, x after a period of population decline. Describe the variables and numbers that you used in your equation. Explain the similarities and differences between your equations in (a) and (b). During what year will the population of city (a) first exceed that of city (b)? Show all of your work and explain your steps. During what year will the population of city (a) be at least twice the size of the population of city (b)? Show all of your work and explain your steps.
