Explanation:
using the parabola formula:
y = a(x-h)² + k²
vertex = (h, k)
We are given a parebola equation of: y = x²+9
comparing both equations to get the vertex:
y = y
a = 1
(x-h)² = x² 
x² = (x + 0)²
(x-h)² = (x + 0)²
h = 0
+k = +9
k = 9
The vertex of the parabola as (x, y): (0, 9)
 
        
             
        
        
        
The equation given in the question is
13 + (w/7) = - 18
(91 + w) / 7 = - 18
91 + w = - 126
w = - 126 - 91
    = - 217
I hope that the procedure is clear enough for you to understand. I also hope that this is the answer that you were looking for and the answer has actually come to your desired help.
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
To see if two events are independent you can use the formula P(a|b) = P(a) 
In this problem P(C|Y) = 35/75 = .4667 and P(C) = 110/300 = 3.667, 
therefore C and Y are not independent events because P(C∣Y) ≠ P(C). 
The answer is choice D

These are vertical angles, meaning they're always the same length.
