Step-by-step explanation:
X in litres is 67% herbicide
y in litres is 46% herbicide
{x+y=42
{0.67x+0.46y=42*0.55
{67x+46y=2310
{46x+46y=1932
21x=378
x=18 litres
A. She need to use 18L
Answer:

(h,k)=(8,-8)
Step-by-step explanation:

From the given equivalent forms of the function g(x), we are to pick which form quickly reveals the vertex.
The vertex form of a parabola is given:
, where (h, k) is the vertex of the parabola.
Therefore, Option A,
quickly reveals the vertex.
From the above, h=8, k=-8. Therefore the vertex (h,k)=(8,-8)
