When randall wakes up on thursday morning there are 15 inches of snow. the metrologist reports that because the air temperature is slowly increasing the snow melts at 1.5 inches per day for next 8 days the extremely cold temperature over the following 3 days will prevent the snow from melting anymore . however the on day 11 of this streak of winter weather the metrologist predicts steady snow for next 5 days but only 1/2 of an inch will accumulate per day. let d represent the time in days science thursday and let h represent the height of snow
graph the function for the height of snow overtime
describe each interval of increase interval of decrease or constant interval

Statement reason 1. δabc is similar to δced. given 2. 3. definition of slope 4. slope of slope of definition of slope 5. slope of × slope of multiplying the slopes 6. slope of × slope of substitution property of equality 7. slope of × slope of simplifying the right side the table contains the proof of the relationship between the slopes of two perpendicular lines. what is the reason for statement 2? a. parallel line segments that meet a common perpendicular line are proportional in length. b. the lengths of vertical and horizontal sides in congruent triangles are in a common ratio. c. trigonometric identities determine the lengths of the legs in a right triangle. d. corresponding side lengths in similar triangles are proportional in length.
