Answer:
F, I only
Step-by-step explanation:
We can see this is a quadratic equation and c is the constant. What changes when we change the constant? It will change the h intercept which we can see is also known as a y intercept (the y axis is renamed as h).
You can also use graphs to visualize this, try changing the constant in the equation and you can see the y intercept change.
so the answer is F, I only.

Answer:
18.84 meters. 
Step-by-step explanation:
The formula for a circle is πr^2. 
πr^2 = 28.26
3.14 * r^2 = 28.26
r^2 = 9
r = plus or minus 3. 
But since this deals with the area of a circle, there is no way a radius can be negative. So, the radius is 3 meters. 
The formula for the circumference is 2πr. 
2 * 3.14 * 3 = 6 * 3.14 = 18.84. 
So, the circumference of the circle is 18.84 meters. 
Hope this helps!
 
        
             
        
        
        
Answer:
Type II error
Step-by-step explanation:
According to the definition of type II error, the type II error arises when we wrongfully accept the null hypothesis. It means that when we accept our null hypothesis and null hypothesis is not correct then type II error arises. So according to situation we are accepting the null hypothesis that the food is safe but it is actually not safe. Hence the given situation represents type II error.
