Answer:
The diagram of the question is missing, I found a matching diagram, and it is attached to this answer
The 3D object produced is a cone with height 8 and diameter 8 (radius 4)
Step-by-step explanation:
A 3 dimensional solid figure can be formed when a 2 dimensional object is rotated about a line without displacing the object.
when the object in the diagram is rotated about line m, the rotation forms an object with a circular base of diameter 8 units (radius 4) from the base of the triangle and height 8 units, and the 3D object formed is called a cone.
Answer:
Therefore,
The surface area is

Step-by-step explanation:
Shape is triangular prism,
Base = b = 9
Height = h = 7
The length of each side of the triangular prism ,
s₁ = s₂ = s₃ = 9
Width of the entire prism
Width = W = 7
To Find:
The surface area = ?
Solution:
Total Surface Area of Prism is given by,

Where,
b = Base
h = Height
s₁ , s₂ , and s₃ = length of each side of the triangular prism
W = width of the prism
Substituting the values we get

Therefore,
The surface area is

Answer:
for this case we have the following functions:
f (x) = x + 8
g (x) = -4x - 3
Subtracting the functions we have:
(f - g) (x) = f (x) - g (x)
(f - g) (x) = (x + 8) - (-4x - 3)
Rewriting:
(f - g) (x) = x + 8 + 4x + 3
(f - g) (x) = 5x + 11
Answer:
D. (f - g) (x) = 5x + 11
