<span>The best and most correct answer among the choices provided by the question is the third choice "f−1(2) = 10"</span>
<span>
(f)^−1(2)<span>
means find the value of f_inverse when it is given 2 as its input.
they don't give you f_inverse, they give you f(x).</span>
I hope my answer has come to your help. God bless and have a nice day ahead!</span>
Answer: -1
Step-by-step explanation:
1-(-1^2)+(-1^3) = 1-1+(-1)= -1
We have solutions of 20% acid and 40% acid.
We need 60 liters of 40% acid.
"t" is liters of 20% and "f" is liters of 40%
We have to set up two equations:
A) t + f = 60
B) .20t + 1.0f = (60*.40)
Multiplying equation A) by -.2
A) -.2t -.2f = -12 then adding that to B)
B) .2t + f = (24)
.8f = 12
forty per cent volume = 15 liters
A) t + f = 60
Twenty per cent volume = 45 liters
