Answer:
A. b2 – 4ac = 0
Step-by-step explanation:
Hey user☺☺
Option a is correct
Because the graph has only one solution.
As the graph touches the x-axis at one point that means that it will have only one solution for x. But we know that a quadratic equation has two solutions. So the graph will have two equal solution and therefore the discriminant will be 0.
Hope this will help☺☺
 
        
             
        
        
        
The next larger hundred is  5,100 .
The next smaller hundred is  4,900 .
5,000  is exactly midway between  4,900  and  5,100.
Neither of them is closer to  5,000  than the other one is.
So  5,000  is already rounded to the nearest hundred.
        
                    
             
        
        
        
Answer:
(- 2, 4 )
Step-by-step explanation:
A translation of 5 units left means subtract 5 from the original x- coordinate.
A translation of 6 units up means add 6 to the original y- coordinate.
Thus
(3, - 2 ) → (3- 5, - 2 + 6 ) → (- 2, 4 )
 
        
             
        
        
        
The number of bats that there would be in 2021 would be 768,000.
<h3>What would be the number of bats in 2021?</h3>
The formula that can be used to determine the future value of bats in 2021 is:
FV = P (1 + r)^n
Where:
- FV = Future value 
- P = Present value = 3000
- R = interest rate = 300%
3000(1 + 3)^4
3000 x 4^4 = 768,000
