An isometry is a transformation that preserves distance.
hope this helps, God bless!
        
             
        
        
        
Use distance formula 
=√(3-3)^2 +(-4-4)^2
=√64
=8
        
                    
             
        
        
        
Answer:
Claim is true that most medical malpractice lawsuits are dropped or dismissed.
Step-by-step explanation:
Given :In a study of 799 randomly selected medical malpractice lawsuits, it was found that 499 of them were dropped or dismissed. 
To Find : Use a 0.05 significance level to test the claim that most medical malpractice lawsuits are dropped or dismissed.
Solution:
n =  799
x = 499 
We will use one sample proportion test  

We are given that the claim is most medical malpractice lawsuits are dropped or dismissed.
Probability of dropped or dismissed is 1/2
  
Formula of test statistic = 
                                         =
                                        = 7.038
p value (z>7.038) is 0
α =0.05
So, p value < α
So, we reject the null hypothesis
So,claim is true
Hence most medical malpractice lawsuits are dropped or dismissed.
 
        
             
        
        
        
Answer:
Surface area = 10.7 in.²
Step-by-step explanation:
Surface Area of triangular pyramid = BA + P*L
Base Area (BA) = ½*nh
b = 2 in.
h = 1.7 in.
BA = ½*2*1.7 = 1.7 in.²
Perimeter (P) = 2 + 2 + 2 = 6 in.
Slant height (L) = 3 in.
Plug in the values 
Surface Area = 1.7 + ½*6*3
Surface area = 10.7 in.²
 
        
             
        
        
        
When the dilation is centered on the origin, you can multiply each of the individual coordinates by the scale factor. 
All the coordinates are ±5 and the scale factor is 1/5. Multiplying those gives ±1. The only selection with all coordinates being ±1 is 
.. Selection A.
You can check to see if the signs agree in detail. (They do.)
