Answer:
203/4
(decimal: 50.75)
Step-by-step explanation:
121/4 − −41/2=
121/4 + 41/2=
121/4 + 82/4=
121 + 82/4
= 203/4
There would be 4096 bacteria cells present.
2^12 = 4096
Let x be the first jug, y the second jug.
From first statement, subtracting 1 from x, makes them equal:
x - 1 = y
From second statement, subtracting 2 from y, makes it half of x:
x/2 = y-2
Solve system with substitution:
x/2 = (x-1) -2
x/2 = x - 3
x- x/2 = 3
x/2 = 3
x = 6
y = x-1 = 6-1 = 5
Therefore the largest jug contains 6 liters.
Answer:
(a) It is a function.
(b) D = [1,2,3,4,5]
(c) R = [40,80,120,160,200]
Step-by-step explanation:
(a) Is this a function?
Yes, in order to be a function we need two groups, in this case "time in days" and "total cost". From this group the first one is called the domain, while the other one is called range. The elements in the domain can only have one associated element in the range. By this definition the graph displays a function.
(b) What is the domain?
The domain of a function are the numbers which represent the possible input. In this case it is the group of integer numbers from 1 to 5, in order words D = [1, 2, 3, 4, 5].
c) What is the range?
The range is the group which represent the output of the function and in this case it is the group R = [40, 80, 120, 160, 200]
