A compass and straightedge are supposed to be part of the required equipment for your class. You are expected to use them here. Your assignment paper should be complete with pencil marks and holes from the compass point. Nobody can do it for you on-line.
Here is a picture of the first one worked. The remaining ones are just like it. The whole assignment should take about 3 minutes, tops.
Answer:
a10 = 25
Step-by-step explanation:
I'm not certain that I have interpreted the question in the way it was intended; however, if I have:
a
10 = 3
(10
) − 5 =
30 − 5 = 25
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
<h3>ANGLE OF ELEVATION</h3>
☞ An angle of elevation is the angle between the horizontal line of sight of the observer to the object above.
<h3>ANGLE OF DEPRESSION</h3>
☞ An angle of depression is the angle between the horizontal line of sight of the observer to the object below.
