A candle holder is in the shape of a triangular pyramid. The area of the base is 15 in2
2 answers:
The volume of candle holder is 30 inches cubed.
Step-by-step explanation:
Given,
Area of base = A = 15 square inches
Height of candle holder = H = 6 inches
As the holder is in shape of triangular pyramid, therefore,
Volume of candle holder =
Volume of candle holder =
Volume of candle holder =
The volume of candle holder is 30 inches cubed.

Answer:
Step-by-step explanation:
If you plot the vertex and the point that it goes through, the point it goes through is above the vertex, so the vertex is a positive one that opens upwards. The general vertex form of a parabola of this type is
We have the x, y, h, and k. We will plug all those in and solve for a. That looks like this:
which simplifies to
-5 = 4a - 13 and
8 = 4a so
a = 2
That means that the paraobola in vertex form is
