Answer:
The correct option is A.
Step-by-step explanation:
If a line passes through two points  and
 and  , then the equation of line is
, then the equation of line is

Let y be the profit (in millions) after x years.
From the given graph it is clear that the line passes through the point (1,-100).
The company paid for these costs and made combined profits of $80 million after 4 years. It means the graph passes through the point (4,80).
The line passes through (1,-100) and (4,80). So, the equation of line is




Subtract 100 from both sides.


The function form is

Therefore, the correct option is A.
 
        
             
        
        
        
Answer: The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle.
The formula for calculating the radius is different from calculating the diameter 
Find radius
r= diameter/ 2 
Radius is half of a diameter 
 While diameter is 
d=2r

Answer:
(x+1)^2 + (y-3)^2 = 16
Step-by-step explanation:
The equation of a circle is given by
(x-h)^2 + (y-k)^2 = r^2
Where (h,k) is the center and r is the radius
(x--1)^2 + (y-3)^2 = 4^2
(x+1)^2 + (y-3)^2 = 4^2
(x+1)^2 + (y-3)^2 = 16
