Answer:
The speed from the observer is 8 mph.
Step-by-step explanation:
When the boat is going downstream with full force, its speed will be the one the oarsman can row on still water added by the flow of the river. In this case he can row the boat at speed of 3 mph, while the stream is 5 mph, so the speed from the observer standpoint is:
The speed from the observer is 8 mph.
Answer:
Original price of bicycle = $864
Step-by-step explanation:
Given:
Rate of tax = 20%
Price pay by Mathew = $1,080
Find:
Original price of bicycle
Computation:
Original price of bicycle = Price pay by Mathew[1 / (1-20%)]
Original price of bicycle = 1,080[1 / (1-20%)]
Original price of bicycle = 1,080[1 / (1-0.2)]
Original price of bicycle = 1,080[1 / (0.8)]
Original price of bicycle = 1,080[1.25]
Original price of bicycle = 1,080[1.25]
Original price of bicycle = $864
Answer:
3
Step-by-step explanation:
4x3=12
now, by traditional method, as "x" progresses towards the positive infinitity, it becomes 100, 10000, 10000000, 1000000000 and so on, and notice, the limit of the numerator becomes large.
BUT, notice the denominator, for the same values of "x", the denominator becomes larg"er" than the numerator on every iteration, ever becoming larger and larger, and yielding a fraction whose denominator is larger than the numerator.
as the denominator increases faster, since as the lingo goes, "reaches the limit faster than the numerator", the fraction becomes ever smaller an smaller ever going towards 0.
now, we could just use L'Hopital rule to check on that.
notice those derivatives atop and bottom, the top is static, whilst the bottom is racing away to infinity, ever going towards 0.
