Consecutive angles of a parallelogram are supplementary, so:

This means  and that
 and that  .
.
Since opposite angles of a parallelogram are congruent,

 
        
             
        
        
        
Answer:
Step-by-step explanation:
radius=diameter/2
=8/2
=4 m
volume of a cylinder =πr^2h
=3.14*(4)^2*13
=40.82*16
=653.12 m^3
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
20 times pop. of Panama = 20×(4×10⁶) = 80×10⁶ = 8×10⁷
Population of Thailand = 7×10⁷ < 8×10⁷
pop of Thailand is less than 20 times pop of Panama.
 
        
             
        
        
        
Answer:
2,-2
In mathematical analysis, the maxima and minima of a function, known collectively as extrema, are the largest and smallest value of the function, either within a given range, or on the entire domain.
 
        
             
        
        
        
Answer:
The function has been flipped due to the negative in front.
The function has been shifted 17 units to the left.
The function has been shifted 4.3 units down.
Step-by-step explanation:
When functions are transformed there are a few simple rules:
•	Adding/subtracting inside the parenthesis to the input shifts the function left(+) and right(-).
•	Adding/subtracting outside the parenthesis to the output shifts the function up(+) and down(-).
•	Multiplying the function by a number less than 1 compresses it towards the x-axis.
•	Multiplying the function by a number greater than 1 stretches it away from the x-axis.
The graph of  compares to
 compares to  in the following ways:
