Answer:
nitrogen is the solvent and oxygen is the solute
Step-by-step explanation:
Most of the time the solute will be present in a smaller quantity and the solvent will appear in a larger quantity.
The coordinates of the vertex are (h,k) so we can write:-
f(x) = a(x -2)^2 - 4
now when f(x) = -7 x = 1 so:-
-7 = a(1-2)^2 - 4
-7 = a - 4
a = -3
so the vertex formula is
f(x) = -3(x - 2)^2 - 4
standard form:-
f(x) = -3(x^2 - 4x + 4) - 4
= -3x^2 + 12x - 16
B. 10, C. 4.9, D. 5.1, E. 5
The area is length x width which means it would be 14 x 8
14 x 8 = 112 so the area of the rectangle is 112 square ft.
