Answer:
D
Step-by-step explanation:
The range is the values of y covered by the graph
The graph on the left shows y going to - ∞
The graph has its maximum value at 4 ( turning point )
The range is therefore
- ∞ < y ≤ 4
Answer:
They are proportional
Step-by-step explanation:
Cross multiply, if the results are the same, they are proportional. If not, well then they're not proportional.
25 × 27 = 675
45 × 15 = 675
They have the same result
They are proportional
In your "<span>^25Log27=a , then ^3log5," your " ^ " has been twice misplaced. The symbol " ^ " always goes between your base (on the left) and your exponent (on the right." Would you please go back to the original question and ensure that you have copied this problem exactly as it was given.</span>
If they meet after 8 hours, then the sum of their average speeds is 600/8=75 km per hour. If one is 5 km per hour faster than the other, then if we set the speed of the slower man to x, we have:
2x+5=75
So:
2x=70
x=30
The fastest man is 5 km per hour faster than the slower, so he travels 35 km per hour.
Answer:
C) The third table. K= 5
Step-by-step explanation:
1) Below there are the missing data:
A proportional relationship through a constant k. It is obtained when we divide:
2)In this case, when we divide the temperature (T) by the time (h).
3)So, examining the table below we are searching for a ratio k common to all measures (temperatures over hour).
