1 km = 1000 meters and 1 hour = 3600 seconds.
9x1000= 9000
9000/3600= 2.5
Your answer would be 2.5 meters per second.
Answer:
1. AAS 2. sorry
Step-by-step explanation:
1. Those angles that are marked are the same. The lengths of the lines too. And the angle H(both) are the same.
2. sorry (what are the choices?)
"Which ... " undoubtedly means "Here are some choices. Pick
the correct one.". Sadly, you decided not to tell us the choices.
There are an infinite number of them.
Here are a few:
(3, 2)
(6, 6)
(9, 10)
(12, 14)
(15, 18)
(18, 22)
(21, 26)
(333, 442)
Answer:
A) f'(t) is negative
B) degc/min
c ) At 20 minutes after the coffee was put on the counter its temperature is 56degc and will decrease by about 1.125 in the next 45 seconds
Step-by-step explanation:
A ) f'(t) is Negative because as the cup of coffee is placed on the counter there is loss of heat from the cup of coffee to the surrounding as t increases hence f'(t) is negative
B ) The units of f'(20) = degc/min
C) At ║f'(20)║ = 1.5 and f'(20) = 56
║f'(20)║ = 1.5 represents the rate of change of temp every 20 minutes = 1.5
therefore after 45 seconds = 3/4 mins. change in temp = (3/4 * 1.5) = 1.125
At 20 minutes after the coffee was put on the counter its temperature is 56degc and will decrease by about 1.125 in the next 45 seconds
