Derive the equation of the parabola with a focus at (6,2) and a directrix of y=1
nydimaria [60]
Distance from focus to vertex=distance from vertex to directix

from (6,2) to y=1, the distance is 1
the focus is 1/2 higher than the vertex
vertex=(6,1.5)

for
(x-h)^2=4p(y-k)
vertex=(h,k)
p=distance from vertex to directix

vertex=(6,1.5)
ditance=0.5

(x-6)^2=4(0.5)(y-1.5)
(x-6)^2=2(y-1.5) is the equation
or
y=0.5x^2-6x+19.5 or
y=0.5(x-6)^2+1.5

Tory and Quentin are the same age. Tory’s younger sister is the same age as Quentin’s younger brother. Tory is 3 years older tha
wariber [46]
Let Tory’s sister age = x

Since Tory is 3 years older than her sister ,

Tory = (x + 3)

let Quentin’s brother age = x

( because quentin’s brother & tory’s sister are the same age , we can let both their ages be x )

Since Quentin is 8 years less than twice his brother’s age ,

Quentin = (2x -8)

Since Quentin and Tory are the same age ,

x + 3 = 2x - 8

-x = -8-3
x = 11

Ans : 11 years old :)


I’m so sorry if this is incorrect

Caleb and Sergio stacked boxes on a shelf. Caleb lifted 14 boxes and Sergio lifted 12 boxes. The boxes that Sergio lifted each w
PilotLPTM [1.2K]

each box weighed 10 more pounds 

and he lifted 12 boxes

 so if you multiply 12 x the weight and then 12 times 10 more pounds each you would have 12c +12*10

which uses the equation 12(c+10)
