The field inside a running track is made up of a rectangle that is 84.39 m long and 73 m wide, together with a half-circle at each end. The track is 9.76 m wide all the way around. What is the distance around the outside of the track? Use 3.14 for pi in your calculations and round to the nearest whole number

e) none of the above because the measure of angle cba is 101°

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
