Answer:
-96.45
Step-by-step explanation:
You take 71.25 and add it to 25.20 because you know that he had 71.25 in is accound already but he went into debt 
 
        
             
        
        
        
I'd say it is A but I think you have made a tpyo
It should be 2*PI*radius^2 + 2*PI*radius*height
        
             
        
        
        
Answer:
39 = r-13
Step-by-step explanation:
 
        
             
        
        
        
The equation of the vertical parabola in vertex form is written as

Where (h, k) are the coordinates of the vertex and p is the focal distance.
The directrix of a parabola is a line which every point of the parabola is equally distant to this line and the focus of the parabola. The vertex is located between the focus and the directrix, therefore, the distance between the y-coordinate of the vertex and the directrix represents the focal distance.

Using this value for p and (3, 1) as the vertex, we have our equation
 
 
        
             
        
        
        
(A)
Choice (B) is not the right answer because I
it's only 3rd order. But because f(x) goes to negative infinity when x goes to positive infinity means that the right answer is (A).
