Answer:
27 pi
Step-by-step explanation:
First find the area of a circle
A = pi r^2
A = pi ^^2
36 pi
We know this is 3/4 of a circle so multiply the area by 3/4
3/4 * 36 pi
27 pi
We do as follows:
let x = amount of 45% solution
y = amount of 30% solution
overall balance => x + y = 450
acid balance => .45x + .30y = .40(450)
Solving simultaneously, we will have:
x = 300 mL
y = 150 mL
This is assuming that partial molar properties does not affect the volume greatly. Hope this answers the question. Have a nice day.
Answer:

Step-by-step explanation:
The given inequality is;

Clear the fraction by multiply through by 30;

Expand;

Group like terms;


Divide through by -19 and reverse the sign.

The second and third function are missing and they are;
The second function; ((2^n) + n^(2))(n^(3) + 3^(n))
The third function is;
(n^(n) + n^(2n) + 5^(n))(n! + 5^(n))
Answer:
A) O((n^(3)) logn)
B) O(6^(n))
C) O(n^(n)(n!))
