If the vertex is at the maximum point they dy/dx=0 at that point...
dA/dx=-2x+4
dB/dx=-2x+8
dC/dx=2x-4
dD/dx=2x-8
So both B and D have a zero velocity at x=4, but only B is equal to 3 when x=4
B. is the correct quadratic with the vertex at (4,3)

Answer:
24
Step-by-step explanation:
EF+FG=EG
5x+9=8x
9=3x
3=x
EG=8x=8*3=24
Answer:
B. 12/13
Step-by-step explanation:
Hypotenuse=
hypotenuse=13
opposite= 5
adjacent= 12
Cosine= adjacent/hypotenuse
cosine= 12/13
