Solution Summary: The author calculates the distance between A and B when the police officer is hiding between two bushes.
A police officer hiding between two bushes
50
ft from a straight highway sights two points
A
, and
B
. The angle from the police car to
A
is
62
°
and the angle to point
B
is
72
°
.
a. Find the distance between
A
and
B
. Round to the nearest foot.
b. Suppose that a motorist takes
2.7
sec to pass from
A
to
B
. Using the rounded distance from part (a), find the motorist's speed in ft/
sec
. Round to
1
decimal place.
c. Determine the motorist's speed in mph. Round to the nearest mph.
For the system consisting of the lines:
and
71 = (-8,5,6) + t(4, −5,3)
72 = (0, −24,9) + u(−1, 6, −3)
a) State whether the two lines are parallel or not and justify your answer.
b) Find the point of intersection, if possible, and classify the system based on the
number of points of intersection and how the lines are related. Show a complete
solution process.
