1. 10
2. 5√2 in
1. The ratio for a 30-60-90 triangle is  x:x√3:2x 
x is the shortest leg  so 2*x =2*5 = 10
2. the ratio of a 45-45-90 triangle is x:x:x√2
x is one leg  so x * √2 = 5*√2 = 5√2
        
             
        
        
        
Answer:
See below.
Step-by-step explanation:
f(x) = -|x + 9|
compared to 
f(x) = |x|
has a graph that opens downward in an upside down V shape.
It has been moved 9 units left compared to the graph of f(x) = |x|.
It reflects over the x-axis.
 
        
             
        
        
        
This is your perfect answer
 
        
        
        
 You would do 3x60=180 since there is 60 minutes in each hour then dives 180 and 20 which gives you 9 batches of cookies. Hope this helps!
        
             
        
        
        
Answer:
See below. 
Step-by-step explanation:
A)
The end behavior is basically how the function behaves as it approaches negative or positive infinity. 
As the function approaches negative infinity, we can see that the graph is going up. In other words: 

As the function approaches positive infinity, we can see that the graph is going down. In other words: 

B)
In even-degree polynomials, both ends of the graph will be going the same way. In this graph, the two ends are going opposite ways so this is an odd-degree function. 
C)
The number of real zeros is simply the amount of times the graph crosses the x-axis. In the graph, the function does this three times. Thus, the number of real zeros is 3.
