Diane will spend more than $31 on gifts. So far, she has spent $18. What are the possible additional amounts she will spend? Use c for the additional amount (in dollars) Diane will spend.
Write your answer as an inequality solved for c.

113.1

step-by-step explanation:

v=4

3πr3=4

3·π·33≈113.09734

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.

to complete this square you have to rotate about the origin 270 degrees clockwise.
