Answer:

1/10 per sec

Step-by-step explanation:

When he's walked x feet in the eastward direction, the angle Θ that the search light makes has tangent

tanΘ = x/18

Taking the derivative with respect to time

sec²Θ dΘ/dt = 1/18 dx/dt.

He's walking at a rate of 18 ft/sec, so dx/dt = 18.

After 3seconds,

Speed = distance/time

18ft/sec =distance/3secs

x = 18 ft/sec (3 sec)

= 54ft. At this moment

tanΘ = 54/18

= 3

sec²Θ = 1 + tan²Θ

1 + 3² = 1+9

= 10

So at this moment

10 dΘ/dt = (1/18ft) 18 ft/sec = 1

10dΘ/dt = 1

dΘ/dt = 1/10 per sec

Find the distance between the points (0,2) and (-4,-4)
Nutka1998 [239]
Distance formula : sqrt ((x2 - x1)^2 + (y2 - y1)^2
(0,2)....x1 = 0 and y1 = 2
(-4,-4)...x2 = -4 and y2 = -4
now we sub
d = sqrt ((-4 - 0)^2 + (-4 - 2)^2)
d = sqrt (-4^2) + (-6^2)
d = sqrt (16 + 36)
d = sqrt (52)
d = 7.2
