Answer:
48 , 21 , 75 - 4.5u
Step-by-step explanation:
The step is above!
Given a sequence; a₁,a₂,a₃...,an,
The common difference is d= a₂-a₁=a₃-a₂=a₄-a₃....
In this case:
a₁=1.05
a₂=1.1
d=a₂-a₁=(1.1)-(1.05)=0.05
Answer: The common difference is 0.05.
Answer: (1, 6) and (12, 72)
Step-by-step explanation:
When you plot the points and use the vertical line test, you'll see that none of the vertical lines go through two points. Therefore verifying that this set of points represents a function.
Calculate how many liters you need to be half full:
50 liters x 50% = 50 x 0.5 = 25 liters to be half filled.
Calculate how many liters are in the tank now:
50 x 0.30 = 15 liters
Now subtract to find how many more liters are needed:
25 - 15 = 10 more liters.
