Answer:
(5,11)
(0,1)
(-2,-3)
Step-by-step explanation:
y=2(5)+1
y=10+1
y=11
so... (5,11)
y=2(0)+1
y=0+1
y=1
so... (0,1)
y=2(-2)+1
y=-4+1
y=-3
so... (-2,-3)
The cross-section cut by the plane yields a quadrilateral with length and width equal to the length and width of the face that is parallel to the plane.
Answer:
(B) Talia is correct. The lateral area can be found by approximating one large triangle, which can be found using the expression 4 (one-half (8) (6.9))
Step-by-step explanation:
Base of the Pyramid = 8 Inches
Height of the Triangular Face = 6.9 Inches
In any solid shape, the Lateral surface area is the sum of all sides except its top and bottom bases.
Since the four triangles are congruent:
Lateral Surface Area = 4 X Area of One Triangle
Area of a Triangle = 
Area of one Triangular Face 
Therefore:
Lateral Surface Area 
Therefore, Talia is correct.
