<span>A parabola that has a horizontal directrix is a parabola that opens up or down.
Here are some of its components:
1) Standard equation of a parabola with a horizontal directrix: (x-h)^2 = 4a(y-k),
a = distance from vertex to focus
2) Vertex at (h,k)
3) Focus(h,k+a)
4) Directrix: y = k-a
5) Axis of symmetry: x = h
A parabola that has a vertical directrix opens to the right or left and is on its side.
Here are some components
1) Standard equation of a parabola with a vertical directrix: (y-k)^2 = 4a(x-h)
2) vertex (h,k)
3) focus (h+a,k)
4) directrix: x = h-a
5) Axis of symmetry: y = k

Answer:
D
Step-by-step explanation:
three meters is 118.11 inches, so if you were to round that you would get 120 inches. That means the answer is D.

Times, and conquer.
Step-by-step explanation:
First half the picture, for the circle and square. so we know the base is 28m, and the length including the circle is 24. So now times the two numbers and bam your answer.
Answer:
Step-by-step explanation:
Let the number of bags of potatoes be x.
We have been given that a grocery store receives a 180-pound crate containing six 10-pound bags of potatoes and an unknown number of 5-pound bags of potatoes.
The weight of 6 potato bags of 10 pound each will be 
pounds.
We can write an equation for the number of bags of potatoes by equating the weight of six 10-pound bags of potatoes and x 5-pound bags of potatoes with 180 pounds.
Therefore, the equation that represents the number of bags of potatoes in the crate is .
