If the temperature drops 3 degrees ever hour, and she monitors it for 5 hours, then the equation would be 3 x 5 = 15. So the temperature ultimately has dropped 15 degrees during the past 5 hours.
        
                    
             
        
        
        
Answer:
The base would be the same since it's the same number. (Base is 7).
You would then subtract 10 by 3 and you would get 7. Answer is 7 to the power of 2.
Hope this helps (:
 
        
             
        
        
        
Answer:
d
Step-by-step explanation:
Given
f(x) = 5x , then substitute x = - 1, that is
f(- 1) = 5 × - 1 = - 5 → d
 
        
                    
             
        
        
        
Answer:
59.4 times greater to the nearest tenth.
Step-by-step explanation:
5,028,000,000,000,000,000,000,000
= 5.028 * 10^24
So the required ratio =  5.028 * 10^24 / 8.46 * 10^22
= 0.594326 * 10^2
= 5.94326 * 10
= 59.4326.
