To find the surface area of a pyramid, we need to find the area of all the faces and add them up.
4 * 6 = 24
24 / 2 = 12
There are four sides (not including the base) in this pyramid, so we should multiply this by 4.
12 * 4 = 48
Now, we find the area of the base.
6 * 6 = 36
We add up all of the numbers:
48 + 36 = 84
84 in^2 is the answer.
Hope this helps!
Answer:
1. -15
2. 35
3. -60
4. 5
Step-by-step explanation:
n = 16:
-5/6(2+16)
-5/6(18)
-15
n= -44:
-5/6(2-44)
-5/6(-42)
35
n = 70:
-5/6(2+70)
-5/6(72)
-60
n = -8:
-5/6(2-8)
-5/6(-6)
5
Step-by-step explanation:
Since we have a vertical directrix, the equation of the parabola is

Where p is the distance from the vertex to the directrix.
or the distance from the vertex to the focus.
Since we have a sideways parabola, let use the point for the directrix is (-6,0). So let find the midpoint of (-6,0) and (6,0). That would be our vertex.


So our vertex is (0,0).
So our equation become

The distance from the focus and directrix is 6.
So p=6.

So p is 6.
Since p is 6,

6 x 60 x 5 would be the equation and all of that put together would be 1,800 vehicles would pass by in an hour.
