Answer: OB) 1cm: 7km
63/9=7
Step-by-step explanation:
Sum of cubes: a^3 + b^3 = (a+b)(a^2 - ab + b^2)
Sum of cubes: x^3*y^3 + 34, or (xy)^3 + (∛34)^3
This factors into (xy + ∛34)*( [xy]^2 - xy∛34 + (∛34)^2 )
Step-by-step explanation:
- -2. =
- -1 =
- 0 = 1
- 1. = 7
- 2. = 49
Answer:
Step-by-step explanation:
If you plot the focus and the directrix on a coordinate plane, because the parabola wraps itself around the focus away from the directrix, we know that this parabola opens to the left. That means its general form is
where h and k are the coordinates of the vertex and p is the distance between the vertex and either the focus or the directrix because both distances are the same. Knowing that both distances are the same, it logically follows that the vertex is directly in between the focus and the directrix. So the vertex is at the origin, (0, 0). p is 2 because the vertex is at an x value of 0 and the directrix is at the x value of 2, and because the focus is at an x value of -2. Filling in the equation, then:
which simplifies to
and, solving for x:
All you gotta do is calculate its volume by using the formula
LengthXWidthXHeightand then divide by 2
