Answer:
400 units³
Step-by-step explanation:
The volume (V) of the square pyramid is
V = 
area of base × height (h)
where h is the perpendicular height.
Consider the right triangle formed by a segment from the vertex to the midpoint of the base and the slant height ( the hypotenuse )
Using Pythagoras' identity on the right triangle
h² + 5² = 13²
h² + 25 = 169 ( subtract 25 from both sides )
h² = 144 ( take the square root of both sides )
h = 
= 12
Area of square base = 10² = 100, hence
V = × 100 × 12 = 4 × 100 = 400

Answer:
y=1/2x+5/2
Step-by-step explanation:
4-3=1
3-1=2
m=1/2x
So now you have y=1/2x
Insert into equation
y=1/2x+?
Now sub you slope in to last points, and you get 5/2
So now you final answer is:
y=1/2x+5/2
