The area of the washer will be the area of the smaller circle SUBTRACTED from the area of the larger circle.
Area of a circle = pi * r^2 where r is your radius (which is half the diameter).
Larger circle area = pi *(diameter/2) ^2.
Smaller circle area = pi * (13.2/2)^2 = pi * 6.6^2 = 136.8484....
So...the area of the washer = larger circle area - 136.4848...
Ion even know lol ask your teacher
Answer:
g(x) = 2x – 3 is the function has an inverse that is also a function.
The correct option is A.
Inverse function;
The inverse of a function is the equation where x and y have switched places.
Here g(x) = 2x - 3 has inverse x = 2y - 3 which simplifies to;
k(x) = - has the inverse x = which simplifies to;
f(x) = |x+2| is an absolute value function.
w(x) = -20 does not have an inverse which is a function.
Therefore
The function has an inverse that is also a function is g(x) = 2x – 3.
