UPPER AND LOWER BOUNDS
helen draws a random circle. she then measures its diameter and circumference. she gets a circumference, c, of 405 mm correct to 3 significant figures. she gets a diameter, d, of 130 mm correct to 2 significant figures. helen wants to find the value of π using the formula π=C/d calculate the lower bound and upper bound for helens value of π. give your answers correct to 3 decimal places.

The equation shown below represents function f. f(x)= -2x+5 the graph shown below represents function g. which of the following statements is true? a. over the interval [2, 4], the average rate of change of f is the same as the average rate of change of g. the y-intercept of function f is less than the y-intercept of function g. b. over the interval [2, 4], the average rate of change of f is greater than the average rate of change of g. the y-intercept of function f is greater than the y-intercept of function g. c. over the interval [2, 4], the average rate of change of f is the same as the average rate of change of g. the y-intercept of function f is greater than the y-intercept of function g. d. over the interval [2, 4], the average rate of change of f is less than the average rate of change of g. the y-intercept of function f is the same as the y-intercept of function g.
