Pi owns a cornfield and has placed fences around four polls, A, B, C, D that delimit the edges of the field. He needs to drive a

round the field every day to check whether anybody has tried to break in. The four poles are located at:
A (-2,1)
B (3,-11)
C (-2,-23)
D (-7,-11)

How many miles will pi drive if he starts at pole A and drives around the entire border of the field?

(please show the work)

Answer:

52 miles

Step-by-step explanation:

A to B:

sqrt( (3 - (-2))^2 + (-11 - 1)^2 )

sqrt( (5)^2 + (-12)^2 )

sqrt( 25 + 144 )

sqrt( 169 )

13

B to C:

sqrt( (-2 - 3)^2 + (-23 - (-11))^2 )

sqrt( (-5)^2 + (-12)^2 )

sqrt( 25 + 144 )

sqrt( 169 )

13

C to D:

sqrt( (-7 - (-2))^2 + (-11 - (-23))^2 )

sqrt( (-5)^2 + (12)^2 )

sqrt( 25 + 144 )

sqrt( 169 )

13

D to A:

sqrt( (-2 - (-7))^2 + (1 - (-11))^2 )

sqrt( (5)^2 + (12)^2 )

sqrt( 25 + 144 )

sqrt( 169 )

13

Adding:

13 + 13 + 13 + 13

Theoretical probabilities are Select one: a. the relative frequencies based on an experiment. b. the short-run relative frequenc
luda_lava [24]

Answer:

Theoretical probabilities are the long-run relative frequencies based on an experiment.

Step-by-step explanation:

Relative frequency or experimental probability is calculated from the number of times an event happens, divided by the total number of trials in an actual experiment.

With theoretical probability, you don't experiment. Instead, you use what you know about the situation to determine the probability of an event occurring.

Experimental probability approaches theoretical probability when the number of trials is extremely large.

Therefore, theoretical probabilities are the long-run relative frequencies based on an experiment.

9. Reflect figure OPQR over the x-axis.
erastovalidia [21]

Answer:

9) P' will be at (-3, -6)

10) T' will be at (0, -1)

11) Quadrant IV

Step-by-step explanation:

9) point P is 3 units away from the y-axis and 6 units away from the x-axis; after reflecting over x-axis it will still be the same distances away from each axis but will be in a different quadrant

10) T is at (5, 6); if translated it will be at (5-5 , 6-7) or (0, -1)

11) a point or shape moves to a new quadrant every 90 degrees
