Answer:
15 or 16. 54 is not listed.
Step-by-step explanation:
pretend that 11 is 0. that means 54 is 43.
then you do 43 divided by 3 or 43/3
but looks like the number 43 isn't divisible. it is 14.33333 repeating decimal.
Same if you really use your time and count. So i dont know if u meant 53 it will be 53 if you meant 56 it will be 16.
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
