The original price is $1624.242424 more than likely it was $1,624.25.
        
             
        
        
        
It would either be 9*(10^3) which would be <em>9000</em>.
Or, it would be (9*10)^3, which equals <em>729000</em>.

First third and last answer
        
             
        
        
        
F(x) = sin(x) + icos(x)
|f(x)| = sqrt(sin^2(x) + cos^2(x)) = sqrt(1) = 1
Therefore, |f(x)| = 1
        
             
        
        
        
Hello!
Here are some rules to determine the number of significant figures. 
- Numbers that are not zero are significant (45 - all are sigfigs)
- Zeros between non-zero digits are significant (3006 → all are sigfigs)
- Trailing zeros are not significant (0.067 → the first two zeros are not sigfigs) 
- Trailing zeros after a decimal point are always significant (1.000 → all are sigfigs) 
- Trailing zeros in a whole number are not significant (7800 → the last two zeros are not sigfigs) 
- In scientific notation, the exponential digits are not significant, known as place holders (6.02 x 10² → 10² is not a sigfig) 
Now, let's find the number of significant figures in each given number. 
A). 296.54 
Since these digits are all <em>non-zero</em>, there are 5 significant figures. 
B). 5003.1 
Since the two <em>zeros are between non-zero digits</em>, they are significant figures. Thus, there are 5 significant figures. 
C). 360.01 
Again, the two zeros are between non-zero digits. There are 5 significant figures. 
D). 18.3 
All of these digits are non-zero, hence, there are 3 significant figures.
Therefore, expression D has the fewest number of significant figures being 3.
