Jerome burns 4 cal/min walking and 10 cal/min running. he walks
between 10 and 20 min each day and runs between 30 and 45 min each
day. he never spends more than an hour running and walking together.
"low much time should he spend on each activity to maximize his
alorie-burning?

answer: '

the distance between points l and m

step-by-step explanation:

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

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.
