Answer:

Rounded to the nearest hundredths: 11.69.
Step-by-step explanation:
I would use the Pythagorean theorem for this problem.
The difference between the highest point and the lowest point of AD is 9.8-7.2 = 2.6, so that would be the height of the triangle. The length/base of the triangle would be 11.4.
Now, just solve using Pythagorean's theorem:

Rounded to the nearest hundredths: 11.69.
I hope this helped you.
 
        
             
        
        
        
Let the complex number be x + iy
Then by the pythagoras therem
17  = x^2 + y^2
D will satisfy this equation
4^2 + (-1)^2  = 17
answer is D  4 - i
        
                    
             
        
        
        
Answer:
C(t) = $28,000(0.811)^t  (Answer A)
Step-by-step explanation:
The value of the car is decreasing.  Thus, by the end of the first year of ownership, the car will have the value $28,000(1 -0.189)^1, where the "-0.189" represents DECAY instead of GROWTH.
Please use " ^ " to indicate exponentiation. 
Then the desired formula is C(t) = $28,000(0.811)^t  (Answer A)
 
        
             
        
        
        
Answer: "B. 
Step-by-step explanation:
The given monomial :  
 
Degree of this monomial = Sum of powers of variables=2+8+1= 11
Let's check all the options
A   
Degree = 8
 B 
Degree = 6+5 =11
C 
Degree = 5+3+2=10
D 
Degree =4+2+3+3=12
We can see that only option B has degree 11.
So, the monomial has the same degree as  is "B.
 is "B.  "
