The answer is b I really. Don’t know don’t trust me
Answer:
![S=(\frac{9}{2},-\frac{3}{2})](https://tex.z-dn.net/?f=S%3D%28%5Cfrac%7B9%7D%7B2%7D%2C-%5Cfrac%7B3%7D%7B2%7D%29)
Step-by-step explanation:
The missing details are:
![T= (0,4)](https://tex.z-dn.net/?f=T%3D%20%280%2C4%29)
--- Midpoint of ST
Required
Determine the coordinates of S
To do this, we apply the mid-point formula:
![M(x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)](https://tex.z-dn.net/?f=M%28x%2Cy%29%20%3D%20%5Cfrac%7B1%7D%7B2%7D%28x_1%2Bx_2%2Cy_1%2By_2%29)
Where
![M(x,y) = (\frac{9}{4}, \frac{5}{4})](https://tex.z-dn.net/?f=M%28x%2Cy%29%20%3D%20%20%28%5Cfrac%7B9%7D%7B4%7D%2C%20%5Cfrac%7B5%7D%7B4%7D%29)
![T(x_1,y_1) - (0,4)](https://tex.z-dn.net/?f=T%28x_1%2Cy_1%29%20-%20%280%2C4%29)
The equation becomes:
![M(x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)](https://tex.z-dn.net/?f=M%28x%2Cy%29%20%3D%20%5Cfrac%7B1%7D%7B2%7D%28x_1%2Bx_2%2Cy_1%2By_2%29)
![(\frac{9}{4},\frac{5}{4}) = \frac{1}{2}(0+x_2,4+y_2)](https://tex.z-dn.net/?f=%28%5Cfrac%7B9%7D%7B4%7D%2C%5Cfrac%7B5%7D%7B4%7D%29%20%3D%20%5Cfrac%7B1%7D%7B2%7D%280%2Bx_2%2C4%2By_2%29)
![(\frac{9}{4},\frac{5}{4}) = \frac{1}{2}(x_2,4+y_2)](https://tex.z-dn.net/?f=%28%5Cfrac%7B9%7D%7B4%7D%2C%5Cfrac%7B5%7D%7B4%7D%29%20%3D%20%5Cfrac%7B1%7D%7B2%7D%28x_2%2C4%2By_2%29)
Multiply through by 2
![2*(\frac{9}{4},\frac{5}{4}) = 2*\frac{1}{2}(x_2,4+y_2)](https://tex.z-dn.net/?f=2%2A%28%5Cfrac%7B9%7D%7B4%7D%2C%5Cfrac%7B5%7D%7B4%7D%29%20%3D%202%2A%5Cfrac%7B1%7D%7B2%7D%28x_2%2C4%2By_2%29)
![(\frac{9}{2},\frac{5}{2}) = (x_2,4+y_2)](https://tex.z-dn.net/?f=%28%5Cfrac%7B9%7D%7B2%7D%2C%5Cfrac%7B5%7D%7B2%7D%29%20%3D%20%28x_2%2C4%2By_2%29)
By comparison:
![x_2 = \frac{9}{2}](https://tex.z-dn.net/?f=x_2%20%3D%20%5Cfrac%7B9%7D%7B2%7D)
![4 + y_2 =\frac{5}{2}](https://tex.z-dn.net/?f=4%20%2B%20y_2%20%3D%5Cfrac%7B5%7D%7B2%7D)
![y_2 =\frac{5}{2}-4](https://tex.z-dn.net/?f=y_2%20%3D%5Cfrac%7B5%7D%7B2%7D-4)
![y_2 =\frac{5-8}{2}](https://tex.z-dn.net/?f=y_2%20%3D%5Cfrac%7B5-8%7D%7B2%7D)
![y_2 =-\frac{3}{2}](https://tex.z-dn.net/?f=y_2%20%3D-%5Cfrac%7B3%7D%7B2%7D)
Hence, the coordinates of S is:
![S=(\frac{9}{2},-\frac{3}{2})](https://tex.z-dn.net/?f=S%3D%28%5Cfrac%7B9%7D%7B2%7D%2C-%5Cfrac%7B3%7D%7B2%7D%29)
Answer:
triangle
Step-by-step explanation:
Cross sections perpendicular to the base and through the vertex will be triangles. Below, you can see a plane cutting through the pyramid, part of the pyramid removed, and the cross section. You could also take a slice parallel to the base. Cross sections parallel to the base will be hexagons
