Please help me with this

Step-by-step explanation:

The geometric mean of 2 numbers a and b is

The third term is the geometric mean of the first and fifth terms, that is

a₃ = = 31.5

The second term is the geometric mean of the first and third terms, that is

a₂ = = 10.5

The fourth term is the geometric mean of the third and fifth terms, that is

a₄ = = 94.5

Thus the sequence is

3.5, 10.5, 31.5, 94.5, 283.5

- "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."

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
