Answer:
32
Step-by-step explanation:
80 x 40 = 3,200
3,200 / 100 = 32
You take 20 / 12 for the inches in a foot and get 1.6 then times by 500 and get 833.3
The function is :
y = √(x-12), x≥12
To find the inverse function, we interchange x and y, and then make y the subject again.
So interchanging x and y we have:
x = √(y-12)
Squaring both sides gives;
x² = y-12
Now making y the subject we have,
y = x² +12
x≥0.
Therefore the inverse function is;
y = x² +12, x≥0.
Hence the correct answer is C.
