Answer:
3 ft/s
Explanation:
given,
distance in west, d₁ = 18 ft
distance in south, d₂ = 24 ft
time taken to travel 42 ft = 10 s
speed of boat in north = x ft/s
Speed of the boat when heading west = (x - 3) ft/s
again using the above formula
now, total time
t = t₁ + t₂
on simplifying
10 x² -72 x + 72 = 0
On solving the above equation we get
x = 6 ft/s
Hence, speed of boat in west direction, 6 -3 = 3 ft/s
speed of boat in south direction = 6 ft/s
Answer;
Uniformitarianism
Explanation;
-Uniformitarianism is the principle suggesting that Earth's geologic processes acted in the same manner and with essentially the same intensity in the past as they do in the present and that such uniformity is sufficient to account for all geologic change. For example, at an active volcano we can observe lava cooling to form layers of basalt.
James Hutton suggested that deep soil profiles were formed by the weathering of bedrock over thousands of years. He also suggested that supernatural theories were not needed to explain the geologic history of the Earth.
Answer:
Deductive
Explanation:
Deductive reasoning or logic is the form of logic where the reasoning process from which the conclusion is reached is based on one or more premises. Deductive logic, is a top down logic, where premises are linked with conclusion, such that true premises give a true conclusion which is reached by a process of narrowing the focus based on certainty
The question bases the conclusion on the premise that the Big Bang theory which is based on scientific evidence is several billions of years old and if the theory is correct the universe <em>(as it is today)</em> was not created six days
