Answer: B - help map the ocean floor
Explanation: GPS which is an acronym for Global Positioning System is a global satellite based location and navigation system owned by the US Government. It was first used by the US Air Force in 1978. It's main purpose is to show a GPS user location and time information from anywhere on earth, where there is an unobstructed line of sight from the precise location to 4 or more GPS satellites. GPS is commonly used on land (obviously through every day use like when you use an uber) and in the air (pilots use GPS signals when they fly).
GPS can be used to track pets if there's a tracking device on their collars.
GPS is also used in taxis and can be used to track a cab after a hurricane.
Ordinary people can use GPS to collect information for scientists - an example of this would be taking a new undefined route on Google maps therefore adding to their archive of known routes/areas.
However GPS signals cannot penetrate water - sea water especially. Hence the answer is B

Less children are being born due to increased efforts to lower the CBR (crude birth rate) and improve contraceptive methods. This results in less children being born, meaning that the older people are increasing in dependency (because there's more older people in the older generations vs the newer)
Answer:
x = 101.1 yd
Explanation:
We are to find the value of x
Angle opposite to x = 11° (alternate angles are congruent)
Reference angle = 11°
Opposite = x
Hypotenuse = 530 yd
Apply trigonometric function, SOH, to find x.
Sin 11 = Opp/Hyp
Sin 11 = x/530
530 × Sin 11 = x
101.128767 = x
x = 101.1 yd (nearest tenth)
