If you ignore friction, the amount of time required for a box to slide down an inclined plane is a
ne is Vg sin 0 cos o 'W
i me, where a is the
horizontal distance defined by the inclined plane, g is the acceleration due to gravity and is the angle of the inclined plane. For what
values of g is the expression undefined?
a. 0°
c. both a &b
b. 90°
d. none

my answer is$ 12

step-by-step explanation:

because 15 -2=12

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.

parallelogram is the   answer
