Answer:
The value of f(-2) is 1/2 or it can be written as 0.5.
Step-by-step explanation:
The given function is

We have to find the value of f(-2).
Substitute x=-2 in the given function to find the value of f(-2).




Therefore the value of f(-2) is 1/2 or it can be written as 0.5.
 
        
             
        
        
        
Answer: 105.84 cm^2
To find the answer, first you have to start by finding the percent of the circle in the sector. Convert the radians given to 108 degrees. 108 out of 360 is 30%. 
Now, find the area of the circle. It's pi x r^2, so the area is 352.810.
Multiply this by 30% to find our area of 105.84 cm^2

Answer: option c
Step-by-step explanation:
 Find the x-intercept and y-intercept of each line.
 To find the x-intercept, substitute  into the equation and solve for "x".
 into the equation and solve for "x".
 To find the y-intercept, substitute  into the equation and solve for "y".
 into the equation and solve for "y".
 
 - For the first equation:
 x-intercept
 
  y-intercept
 
 Graph a line that passes through the points (7.25, 0) and (0, 9.66)
 - For the second equation:
  x-intercept
 
 
  y-intercept
  
 Graph a line that passes through the points (0.5, 0) and (0, -0.33)
 Observe the graph attached. You can see that point of intersection of the lines is (5,3); then this is the solution of the system. Therefore:
