Answer:875
Step-by-step explanation:
Answer:
f(2) = -6
f inverse of 1/2 is 17/2
Step-by-step explanation:
We are given a function
To solve for part (a), we have to substitute x = 2 in f(x).
Therefore, f(2) is -6.
Now we solve for part (b), we see the notation which is a minor different similar to f(x). We see that there is exponent of -1 between f and 1/2. The part (b) indicates that the function is an inverse of f(x).
To solve for part (b), first we solve for x in the function. Let f(x) = y.
Multiply both sides by 2x-5.
Divide both sides by y-term.
Then swap x and y which we receive
Therefore,
Thus,

Answer:
Here is how to do it.
Step-by-step explanation:
First, find the area of the bigger circle. The equation to find the area for a circle is A=πr². You know that the diameter is 1.2 inches, so divide by 2 to find the radius.
Next, find the area of the smaller circles. Using the same process, find their area and multiply by 4, as there are four circles in the picture.
Subtract the total area of the smaller circles and the big circle to find the area.
Equation:
Total area of the big circle - total area of small circles = area of the button
