Answer:
f(x)=-4x+/4
let y=f(x)
y=-4x+4
interchange the role of x & y
x=-4y+4
x-4=-4y
(x-4)/-4=y
y=-(x-4)/4
f-¹(x)=-(x-4)/4
yeah you are right
Answer:
a) 11%
b) 56%
Step-by-step explanation:
a) A= πr^2 6^2π= 36π A= 18^2π = 324π
36π/324π = .111111111111111111111111 or 11%

b) A= πr^2 18^2 π = 324π
A= πr^2 12^2π = 144π
324 – 144 = 180
180π/324π = .5555555555555555555555556 or 56%

Answer:
7 batches
Step-by-step explanation:
Since they expect to put 16 songs, but actually end up putting 50% more, we can do 16 * 150 % which would equal 24 songs that they actually put on their CD.
During the editing process, they removed 75 % of the songs they put on their CD. Since they put 24 songs on their CD, we can do:
24 * 25 % (because this would equal the songs left after the editing process, and not the actual number of songs removed, which is 75 %) which would equal 6 songs.
There would be 6 songs left on their Final CD.
