Step-by-step explanation:
A transformation may be defined as taking a basic function and then changing it slightly with the predetermined methods. This changes will cause the required graph of that function to shift, move or stretch, which depends on the type of the transformation.
For example:
Let a function be :
For any constants m and n, the function shifts the parent function.
- vertically n units and in same direction of the sign of n.
- horizontally m units and towards the opposite direction of the sign of m.
- The y-intercept becomes ()
- The horizontal asymptote becomes y = n.
- the reflection about x -axis becomes
Answer:
Area of the square base: 144 in²
Area of each triangular face: 66 in²
Amount of paint needed: 408 in²
Step-by-step explanation:
We basically want to find the surface area of this square pyramid.
First, find the areas of the 4 triangular sides. The area of a triangle is denoted by: , where b is the base and h is the height.
Here, the base coincides with the side length of the square, so b = 12. The height is 11, so h = 11. Plug these in:
* 12 * 11 = 66 inches squared
Each triangular face is thus 66 inches squared.
Since there are 4 triangles, multiply 66 by 4: 66 * 4 = 264 inches squared
Now, find the area of the square base. The area of a square is: A = s * s, where s is the side length. Here, the side length is 12, so s = 12. Plug this into the equation:
A = s * s
A = 12 * 12 = 144
So, the square base is 144 inches squared.
Finally, add 144 to 264 to get the total area Gabriel needs to paint:
144 + 264 = 408 inches squared
