Answer:
Option 3- Polygons
Step-by-step explanation:
Given : The faces of the polyhedron
To find : Which term describes the faces of the polyhedron?
1) Circles
2) Spheres
3) Polygons
4) line segments
Solution :
A polyhedron is a three-dimensional figure with flat polygonal faces, straight edges and sharp corners or vertices.
or a polyhedron is a closed, solid object whose surface is made up of a number of polygonal faces.
The definition itself clear that term describe the faces of the polyhedron is a polygons.
Therefore,Option 3 is correct.
Answer:
36 units
Step-by-step explanation:
Area is the inside of the shape
so
2×2×2=6
6×6= 36
Answer:
b
Step-by-step explanation:
One A
y = e^x
dy/dx = e^x The f(x) = the differentiated function. Any value that e^x can have, the derivative has the same value. x is contained in all the reals.
One B
y = x*e^x
y' = e^x + xe^x Using the multiplication rule.
You want the slope and the value of the of y to be the same. The slope is y' of the tangent line
xe^x = e^x + xe^x
e^x = 0
This happens only when x is very "small" like x = - 4444444
y = e^x * ln(x) Using the multiplication rule again, we need the slope of the line with is y'
y1 = e^x
y1' = e^x
y2 = ln(x)
y2' = 1/x
y' = e^x*ln(x) + e^x/x So at x = 1 the slope of the line =
y' = e^1*ln(1) + e^1/1
y' = e*0+e = e
y = mx + b
y = ex + b
to find b we use y= e^x ln(x)
e^x ln(x) = e*x + b
e^1 ln(1) = e*1 + b
ln(1) = 0
0 = e + b
b = - e
line equation and answer.
y = e*x - e
