Answer:
Step-by-step explanation:
Given
Solving (a): Set of ordered pair
A function y = f(x) is represented as (x,y)
So, the ordered pair of V is:
Order the alphabets in increasing order
Solving (b): The domain and the range
In a function 
The domain and the range are represented as:
So, we have:
Ni : Zn: Cu = 7:2:9 =7x : 2x : 9x
7x+2x+9x = 3.8
18x=3.8
x=3.8/18=1.9/9≈0.21
Ni: 7x=7*0.21=1.47 ≈1.5 kg
Zn: 2x=2*0.21=0.42≈0.4 kg
Cu: 9x=9*0.21=1.89 ≈1.9 kg
Check 1.5+0.4+1.9 =3.8 True
51.5 Hectograms + 5100 Grams
51,500 Decigrams = 5100 Grams
They have same mass because they equal each other.
Answer:
The answer 2.456*10^11
Step-by-step explanation:
To to this we have to count how many decimals from the back of the number
245,600,000,000
We can actually count 11 decimal points from the back
Hence in standard form or scientific notation we have
2.456*10^11
