Answer:
n = r - 2.5
Step-by-step explanation:
We have the following data:
7 4.5
8 5.5
10 7.5
12 9.5
Now, what we will do is what happens if we subtract each one:
7 - 4.5 = 2.5
8 - 5.5 = 2.5
10 - 7.5 = 2.5
12 - 9.5 = 2.5
The difference is always kept constant, therefore the equation would be:
n = r - 2.5
Answer:
2.6768·10^(-14) (Answer C)
Step-by-step explanation:
Problem 4: We ADD the powers of 10: 10^6·10^(-3) = 10^3. Also, 3.6·1.7 = 6.12. Therefore, Answer D is correct.
Problem 5: Again we ADD (combine) the powers of 10: 10^(-10)·10^(-5) =
10^(-15). 4.78·5.6 = 26.768. Our intermediary answer is thus:
26.768·10^(-15). This must be rewritten in the form x.xxxx, so here we have:
2.6768·10^(-14) (Answer C)
The answer is sunlight :)
