O square prism
O square pyramid
O cone
The solution is Option C.
The figure represents a square pyramid
The total surface area is the summation of the areas of the base and the three other sides. A = B + ( 1/2 ) ( P x h ), where B is the area of the base of the pyramid, P is the perimeter of the base, and h is the slant height of the pyramid
Surface Area of Pyramid = B + ( 1/2 ) ( P x h )
Volume of Pyramid = ( 1/3 )a²H
where B is the area of the base of the pyramid, and h is its height.
Given data ,
Let the figure be represented as A
Now , the figure A is not a triangular prism as the base of the prism is not a triangle
And , the figure A is not a square prism as the top of the prism is not a square
Furthermore , the figure A is a square pyramid as the base of the pyramid is a square
And , it is not a cone because the base is not circular in shape
Hence , the figure is a square pyramid

b) Find the y-coordinate of the vertex. Show all work leading to your answer and write the answer in simplest form.
c) What does the vertex represent for this situation? Write 1 - 2 sentences to explain your answer.
Answer:
Step-by-step explanation:
We can find the vertex either by completing the square or taking advantage of the simple formula x = -b / (2a), which provides the x-coordinate of the vertex.
Here a = 2, b = -20 and c = 100. Then the x-coordinate of the vertex is at
x = -(-20) / (2*2), or x = 5.
Next, evaluate y = 2x^2 - 20x + 100 to find the y-coordinate of the vertex. It is y(5) = 2(5^2) - 20(5) + 100, or y(5) = 50 - 100 + 100, or 50. y = 50.
The vertex is at (5, 50). This states that the stock reaches its minimum value, $50 per share), after 5 months. From that time on, the stock appreciates (increases) in value.
