4. Diego props a 10 ft ladder against a wall. How high up on the wall will the ladder reach, if the foot of the ladder is 5 feet away from the wall?
Pythagorean

- "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."

your question is incomplete, write all the numbers in the sequence that it tells you.  

step-by-step explanation:

faster, im not sure why but i know it is faster
