Question 13 of 20 Martina is a skydiver. She jumps out of a plane and free-falls for almost 80 seconds, reaching a terminal velocity. Then she opens her
parachute and slows down, reaching another terminal velocity. Finally, she lands. The graph of her velocity (in meters per second) over
the time (in seconds) of her dive is sketched,

Whit h equation best represents this situation the number 98 increased by an unknown number equal to 120

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.
