In scientific notation, just move the decimal point over however many numbers are in the power. 
In 7.003 • 10^4, move the decimal point over 4 places to the right, (or left if it's negative) making it 70,030
        
                    
             
        
        
        
Answer:
m∠Q ≈ 53°
Step-by-step explanation:
To find the measure of ∠Q, the law of cosines will need to be used. Lowercase letters represent the side lengths, while upper case letters represent angles. 
In this situation, 'A' will be ∠Q. Therefore:
17² = 18² + 20² -2(18)(20)cosQ
Simplify:
289 = 324 + 400 -2(360)cosQ
Continue simplifying down:
-435 = -720cosQ
Divide both sides by '-720':
0.604 = cosQ

m∠Q ≈ 52.83 or 53° rounded to the nearest whole degree.
 
        
             
        
        
        
3.482 x 10^9.
-the coefficient must be under 10, and in this case it is the "3". Then you count the places after that to get your exponent
        
                    
             
        
        
        
Answer: -8
Step-by-step explanation:
When x = 5, f(x) = -8.
 
        
             
        
        
        
2 pieces of squid = $3.50 
Therefore 1 piece of squid = $1.75 (3.50÷2)
1 piece of eel = $3.25
3 pieces of tuna = $6.75
Therefore 1 piece of tuna = $2.25 (6.75÷3)
4 pieces of crab = $8.00 
Therefore 1 piece of crab = $2 (8÷4)
Put them in order of price and you get 
$1.75 , $2 , $2.25 , $3.25
