Answer:
B) Parabola
Explanation: The function sunrise can be seen as the function
F( t = day of the year ) = hour of the day when the sun appears.
There are two important days in a year: - 21 of July, the summer solstice, and, -21 of December, the winter solstice.
The 21 of July is the day of the year when the sun appears the earliest, and, the 21 of December is the day of the year when the sun appears the latest.
We measure the sunrise in on year, i.e, 366 days, we begin to measure the 21 of December and end our measurements the 21 of December of the next year. Hence, t=0 corresponds to the 21 of December, t=366 corresponds to the 21 of December of the next year and t_mid=366/2 corresponds to the 21 of July.
It holds that F(0)=F(366) is the minimum of the function and F(t_mid) is the maximum of the function. Between t=0 and t_mid F(t) is decreasing, also between t_mid and t=366 F(t) is increasing. Moreover, by the way that the earth travels around the sun, we can assume that F(t) is symmetric with respect to t_mid. Finally, by plotting or drawing F(t), for t between 0 and 366, looks like a parabola facing downwards.
False, graphs are always used for comparisn
Answer:
Both more-developed and less-developed regions have become increasingly urbanized since 1950
Explanation:
since all bars are rising increasingly over time it show that urbanization of reagions has greatly increased from 1950 showing that more people live in more urban regions now than back then
<span>Selection (a) is the best answer. Rainforests, through their ecosystems, are able to mitigate the effects of prolonged rain events and droughts that could take place in the areas in which they reside. The expansive canopies and tall trees hold in the moisture that does fall to make sure that the areas within them receive sufficient moisture for growth.</span>
Answer:
As San Francisco and other cities in the Bay Area commemorate the anniversary of the 1989 Loma Prieta earthquake, we are reminded once again of the need to get prepared for the next natural disaster. The 6.9 magnitude earthquake not only resulted in collapsed homes, displacement of residents, but it also was a terrifying reminder of the need to reinforce the structures we use every single day.
I hope this helped, have an awesome day!
