A skydiver is 1,200 meters above the ground when she opens her parachute. After opening the parachute, she descends at a constant speed of 7 meters per second. Write an equation to model the height of the skydiver above the ground, using h to represent her height above the ground and s to represent the number of seconds since she opened her parachute. Choose the correct number to fill in the blank h = s +

step-by-step explanation:

i just used a calculator

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
