Jace ordered a banner in the shape of a parallelogram from a print shop. A parallelogram is shown. The length of the sides are 9 feet, and the length of the top and bottom sides are 12 feet. A diagonal is drawn from one point to the opposite side. The length of the diagonal is 19 feet. Heron's formula: Area = StartRoot s (s minus a) (s minus b) (s minus c) EndRoot The print shop charges $1.10 per square foot for banners of any shape and size. What is the approximate cost of the banner before tax? $41.95 $46.14 $83.90 $92.30

92.30

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."
