The points N(-3,-3)(−3,−3), O(-3,-9)(−3,−9), and P(5,-3)(5,−3) form a triangle. Plot the points then click the "Graph Triangle" button. Then find the perimeter of the triangle. Round your answer to the nearest tenth if necessary.

Perimeter = 30.42

Step-by-step explanation:

Using Distance Formula, √((x2-x1)^2 + (y2-y1)^2)

Find the Distance Between NO, OP, and NP

√((-3 - -3)^2 + (3 - 9)^2) - NO = 6

√((-3 - 5)^2 + (9 - -3)^2) - OP = 14.42

√((-3 - 5)^2 + (3 - -3)^2) - NP = 10

Sum All of Them = 10 + 6 + 14.42 = 30.42

step-by-step explanation:

f

- "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."
