Answer:
The answer to your question is 12.55 cm
Step-by-step explanation:
Data
Adam Cara
height = 159 cm height = 140 cm
shadow = 105 cm shadow = x
Process
1.- To solve this problem use the Thales' theorem
Cara's shadow / Cara's height = Adam's shadow / Adam's height
- Substitution
x / 140 = 105 / 159
-Solve for x
x = 105 (140) / 159
-Simplification
x = 14700 / 159
x = 92.45 cm
Cara's shadow is 92.45 cm long.
2.- If both shadows are in line, then Cara must walk forward
105 - 92.45 cm
12.55 cm
Answer:
-103
Step-by-step explanation:
So we have the sequence:
14, 11, 8, 5...
First, note that this is an arithmetic sequence because there is a common difference.
Each subsequent term is three less than the previous term.
To find the 40th term, we can write an explicit formula.
The standard form for an explicit formula for an arithmetic sequence is:

Where a is the initial term, d is the common difference, and n is the nth term.
We know that the initial term is 14. The common difference is -3 because each term is <em>minus</em> 3 the previous one.
Substitute in a and d:

We want to find the 40th term. So, substitute 40 for n:

Subtract:

Multiply:

Subtract:

So, the 40th term is -103.
Answer:
I think its different from each other because maybe combining like terms in a inequality your trying to compare them? Or maybe they're just advanced. Can someone give me an example of an inequality please so I can try finding out the difference?
Answer: The answer is Iπ + √17|.
