Consider an isosceles triangle a with base 10 and height 12. consider another triangle b formed using vertices which are the center of the sides of triangle a. consider another triangle c whose vertices are similarly formed from b. repeat this process ad infinitum. express the sum of the areas of all such triangles using a series and its closed form sum. compute the areas (a) by using only the first two terms of the series and (b) by using the closed form of the series sum. write a program to find the sums and use shifts to compute. what is the difference in the two computed sums?

step-by-step explanation:

- "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."
