You should calculate( the area of a circle of radius 15 cm ) minus the area of the circle of radius (15 cm - width of the frame). I am not able to read the number, sorry.
That is the surface area of the frame.
Then, if area of circle radius is 100%, the % of face of the clock is:
(100xareaCircle(15cm-widthframe))/areaCircle15cm
The second table, because -1 x 3 = -3
-3 - 3 = -6 therefore, the second table matches the equation y= 3x -3
Answer:


Step-by-step explanation:
Given

Required
Determine: 
First, we calculate f(x + h)



So, we have:






Times the two to get your answer.
