Answer:
, 
Step-by-step explanation:


Here a=1, b=2 and c=8
To solve this problem you must apply the proccedure shown below:
1. You have that the <span>parabola is 12 meters high at the vertex and at a height of 10 meters, the width is 8 meter.
2. Therefore, you have:
x^2=-4a(y^2-k)
4</span>^2=-4a(10-12)
16=-40a+48
16=8a
a=16/8
a=2
y=0
x^2=-8(0-12)
x^2=96
x=√96
x=9.79x2
x=19.58
3. Therefore, as you can see, the answer is: 19.58 meters.<span>

DSM stands for Diagnostic and Statistical Manual of Mental Disorders. DSM is aclassification system for the mental disorders and indicates how the disorder can be distinguished from other. The DSM-5 recognized anxiety disorders are: generalized anxiety disorder, phobic disorder, panic disorder and obsessive compulsive disorder. <span>Approximately 3 percent of the population are diagnosed with panic disorder using DSM criteria.</span>
The outlier is the number that’s farther away from the others, in this case it’s 9. The mean is the average of all the data points so it is 77/20 or 3.85. Finally, the range is the highest number minus the lowest number, so the range is 8.
