Answer: D
Step-by-step explanation:
If the equation is f(x) = 9x^2 -12, you can solve for the inverse by switching the x and y like this.
x = 9y^2-12.
Then you solve for y.
x = 9y^2-12.
x+12=9y^2
y^2=(x+12)/9
y=sqrt((x+12)/9)
y=sqrt((x+12))/3 which is D
Answer:
Step-by-step explanation:
If the price od 1 scallions weight 6ounces, 6 bunches of scallion wwill weight 6(6) i.e 36 ounces.
Cost price = 36 ounces.
%Loss = 19%
Get the selling price
%Loss = 36-Sp/36 * 100
19 = 36-Sp/36 * 100
0.19 = 36-Sp/36
0.19 * 36 = 36-Sp
7.41 = 36-Sp
Sp = 7.41 + 36
Sp = 43.41 ounces
If after cleaning you have 29.5 ounces of cleaned scallions, then then;
% gain = 43.41-29.5/29.5 * 100
%gain = 13.91/29.5 * 100
%gain = 47.2%
Hence the yield percent id 47.2%
