Answer:
Step-by-step explanation:
The surface area of a square pyramid is the sum of the area of the squared base + 4 times the area of each triangular face, therefore:
where:
is the area of the base, where
L is the length of the base
is the area of each triangular face, where
h is the height of the face
Substituting,
For the model in this problem,
L = 12
h = 8
Therefore, the surface area here is:
A) i think is correct andewmer
<span>Yes, it is a parallelogram because the slope of segment AB equals the slope of segment DC, which equals negative start fraction four over three end fraction, and AD = BC = 10 units.</span>
Answer:
y = 23x-82
Step-by-step explanation:
The equation is written in the form y = mx+b
We need to find the slope
m = (y2-y1)/(x2-x1)
= (79-56)/(7-6)
= 23/1
The slope is 23
y= 23x +b
Put in a point for x and y to determine b
10 =23(4) +b
10 =92 +b
Subtract 92 from each side
10-92 = 92-92 +b
-82 =b
The equation is
y = 23x-82
