Answer:
d. vertical line
Step-by-step explanation:
A line with an undefined slope is a vertical line
Slope is the change in y over the change in x
When the slope is undefined, it means that the x does not change, which is a vertical line
 
        
                    
             
        
        
        
Answer:
45 square inches
Step-by-step explanation:
Akira receives the prize at the science fair for having the most informative project her trophy is in the shape of a square pyramid and is covered in shiny gold foil how much gold foil did it take to cover the trophy including the bottom
Total surface  =  surface area of the base square + area of 4 triangles
Calculate the surface area of the base square
 surface area of the square =  s^2
where s= side length
s=3 in
The surface area of the base  =s^2 
=3^2 
= 9 square inches
The surface area of the side triangles
The area of the triangle = (1/2)* side length* slant height
Side length=3 in
Slant height=6 in
substituting the values,
The area of the triangle =1/2*3*6
= 18/2
= 9 square inches
There are 4 triangles
The area of 4 triangles  =  4 x 9  
= 36 square inches
Therefore,
Total surface  =  surface area of the base square + area of 4 triangles
 =  9 + 36
 = 45 square inches
