At 5:15 p.m. on May 1, 2022, the population of Brazil was 215,353,593. There is one new person in Brazil every 0.39 minutes. Write a linear function to model the population of Brazil as a function of the number of minutes that has passed since 5:15 p.m. on May 1, 2022. f(x)= 100/39 + 215, 353, 593 f(x) =39/100 + 215, 353, 593 f(x) = 215, 353, 5932 + 100/39 f(x) = 215, 353, 5932x + 39/100

As it has important applications in the health sector, such as imaging for diagnoses and graphical representation of heartbeats, it is important to know how to distinguish trigonometric ratios. Thus, by definition, the sine is the ratio between: A. hypotenuse and opposite side (in that order). B. adjacent and opposite sides (in that order). W. opposite side and hypotenuse (in that order). D. hypotenuse and adjacent side (in that order). AND. one and opposite (in that order).
