Answer:
Directrix equation: y = 11/2
y = k - c = 6 - 1/2 = 11/2
Step-by-step explanation:
y=(1/2) x^2+6x+24
factor this
y = (1/2)* [ x^2 + 12x ] + 24
y = (1/2)* [ x^2 + 12x + 36 - 36] + 24
y = (1/2)* [ (x + 6)^2 - 36] + 24
y = (1/2)* (x + 6)^2 - 18 + 24
y = (1/2)* (x + 6)^2 + 6
y - 6 = (1/2)* (x + 6)^2
2*(y - 6) = (x + 6)^2
4c = 2, (h, k) = (-6, 6)
c = 1/2
Directrix equation: y = k - c = 6 - 1/2 = 11/2

mike's final position relative to the ground is 3 feet's underground
Step-by-step explanation:
We take positive value when he is above the ground and then take negative value when he is below or underground
6 feet's underground = -6
He climbs up 14 feet = +14
He climbs down 11 feet = -11
We are required to find his last position relative to ground level
= -6+14-11
= (-6) + (-11) + 14
= -17 + 14
= -3
So we have it that mike's final position relative to the ground is 3 feet's underground
