Find the amount and compound interest of 1½ years at 10%.p. a, compounded half-yearly​

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

- "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."

a ≈ 172.05
