Create a model to represent how much in commission the sales person makes on their daily total sales. Assume, the
sales clerk sold $1,200 worth of merchandise today and
earns 7% on their total sales.

cosine

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."

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
