Answer:
5 inches per hour
Step-by-step explanation:
For this case we have that the volume of the square pyramid is given by:
V = ((L ^ 2) * (h)) / 3
Where,
L: side of the base
h: height
Substituting values we have:
V = ((230 ^ 2) * (147)) / 3
V = 2592100 m ^ 3
Answer:
the volume of the pyramid is:
V = 2592100 m ^ 3
Answer: How many greeting cards he sells
Step-by-step explanation:
The cards are 5 dollars each. 1.99 for shipping is all the same. The only thing that changes is the amount that he sells. So the amount of Greeting cards sold is the dependent variable.
A parabola is a mirror-symmetrical U-shape.
- The equation of the parabola is

- The focus is

- The directrix is

- The axis of the symmetry of parabola is:

From the question, we have:


The equation of a parabola is:

Substitute the values of origin and vertex in 



Collect like terms

Solve for a

Substitute the values of a and the vertex in 

The focus of a parabola is:

Substitute the values of a and the vertex in 




The equation of the directrix is:

So, we have:
----- the directrix
The axis of symmetry is:

We have:

Expand

Expand


A quadratic function is represented as:

So, we have:


Recall that:

So, we have:


This gives


Hence, the axis of the symmetry of parabola is:
