a substantial snowstorm is hitting the Northeast region and is predicted to snow at a rate of 2 inches per hour for the first three hours of the storm. The storm is supposed to pause for three hours and then resume a rate of one hawfinch per hour for the next four hours. the depth, D, of the storm's the total number of inchesnof snow that has fallen at a given time. determine the piecewise linear function for D as a function of the number of hours t, since the storm began. There should be three formulas. the first two should be relativ

answer with step-by-step explanation:

a. ∠j is supplementary to ∠k - true:

(opposite angles of a trapezoid are supplementary which means that they add up to 180 degrees)

b. kl is parallel to jm - true:

(opposite sides are parallel to each other in a trapezoid)

c. jk is perpendicular to kl - false:

(clearly, jk does not make a right angle with kl)

d. jk is parallel to lm - false:

(jk and lm are two lines opposite in direction to each other so they cannot be parallel)

e. ∠j is congruent to ∠m - true:

(the angles on each side of the base are congruent)

f. ∠j is congruent to ∠k - false:

(the angles on the same side but opposite side of the base are not congruent)
