<span>Find the focus and directrix of the parabola with the given equation. Then graph the parabola.
y^=-12x
**
y^2=-12x
This is an equation of a parabola with a horizontal axis of symmetry.
Its standard form: (y-k)^2=4p(x-h), with (h,k) being the (x,y) coordinates of the vertex.
For given equation:
Vertex(0,0)
4p=12
p=3
Focus:(-3,0)
Directrix: x=3
see the graph below as a visual check on the answers:
..
y=±(-12x)^.5</span>
√52-√13+√117
sqrt (4*13) - sqrt (13) + sqrt (13*9)
sqrt(4)sqrt(13) -sqrt(13)+sqrt(13)sqrt(9)
2sqrt(13) -sqrt(13)+3sqt(13)
sqrt(13)[2-1+3]
4sqrt(13)
Choice A
Answer:
Arithmetic
Step-by-step explanation:
It is arithmetic because it keeps adding 6.




therefore, being Arithmetic.
Hope this helped!
brainliest please!
Answer:
yeah it is
y is directly proportional to x
proportionality constant is 9
120% of
85 is 102
Change the percentage to a decimal by dividing it over 100:

Divide 102 by 1.2:
