Answer:
It means goes up by twos for example 2,4,6,8 all those numbers increase by 2s.
Step-by-step explanation:
A number decreased by three square is: (where x is the number)
x - 3^2
We know that
area of the circle=pi*r²
if 360° (full circle) has an area of-------------> pi*r²
110°------------------------------> 40 units²
pi*r²=40*360/110--------> pi*r²=130.91------> r²=130.91/pi-----> r²=41.69
r=6.46 units
the answer is
the radius is 6.46 units
F(13) means x equals 13.
Replace x in the equation with 13 and solve:
-13 + 3 = -10
F(13) = -10
Sorry if my handwriting sloppy.
I showed all of it step by step.
