Answer:
Step-by-step explanation:
The standard form of a circle is

If we are given x and y as 0 and 5 respectively, and we are also told that the center is (0, 0), our h and k are both 0. Filling in x, y, h, and k we can find the radius. So let's do that:
 and
 and
 so
 so
 Our circle's equation is
  Our circle's equation is
 
 
Since the point in question, (4, 4), lies in the first quadrant, we will concentrate on that quadrant only. To fall within the circle, we can set up an inequality and test the point (4, 4). If it lies ON the circle then the equality would be true. Let's try that first:

Obviously, 16 + 16 does not equal 25, so that point (4, 4) does not lie ON the circle. In fact from that statement alone, we can determine that the point lies outside the circle because

If the inequality < were true then the point would lie inside.
 
        
             
        
        
        
Answer:
F(-1/4)=4x-18
F(-1/4) = 4 (-1/4) - 18
F(-1/4) = -19
Step-by-step explanation:
You would have to replace the given numbers and just do the math

8/15 x 5/6 
•multiply across the numerator and denominator. 
= 40/90 
• then find a common factor that will go into both the numerator and denominator equally.
Common factor: 5 
= 8/18
•there is another common factor, which is 2
Simplified:
=4/9
