Answer:
You are right
Step-by-step explanation:
So basically find the absolute maximum of the graph that the function creates, the highest peak is the spot with the greatest y-value, in this case is (60, 1600).
The x-value that creates the greatest y is also the x-value of the vertex for that function of yours (since your function has end behavior of both ends down). To find the x-value of the vertex, get the average of the 2 x-intercepts. So (20+100)/2, which is 60.
I solved it on your other posting of it. x = 12
All of the steps are there
<span>The correct answer for this question is B - the greatest whole number that rounds to 456, 900 in this instant would be 456, 850. 456, 850 to the nearest 100 would be 465, 900. The alternative answers for this question all round to different whole numbers.</span>
You are just taking plus and minus numbers.
You start at 62.3
You go up 13.9
Then you go down - 21.5
End temperature = 62.3 + 13.9 - 21.5
Edm temperature = 54.7 <<<<< answer
Answer:
The sprinter
Step-by-step explanation:
Change cyclist to same units as sprinter (m/s)
20 km = 20x1000 m = 20000 m
1 hour = 60 minutes = 60 x 60 = 3600 sec
So 20 km/hr = 20,000 m / 3600 sec = 5.6 m/s
The sprinter is faster as he travels at 8 m/s.
(Similarly if you change the sprinter's speed into km/hr
you should get 28.8 km/hr)
