The inner loop of insertion sort is designed in a way that puts an element into its final position. Therefore, the given statement is 'true'.
Insertion sort is a simple sorting algorithm that works similarly to the way you sort playing cards in your hands. In the insertion sort, the array is virtually split into a sorted and an unsorted part. Values from the unsorted part of the array are picked and placed at the final position in the sorted part.
So in conclusion, it is stated that in the insertion sort algorithm, the inner loop picks an element and places it into its correct position.

It is false that the first-fit memory allocation algorithm is slower than the best-fit algorithm (on average).
The operating system must maintain a list of each memory location, noting which ones are free and which ones are busy, for both fixed and dynamic memory allocation schemes. The available partitions must then be assigned as new workloads are added to the system.
Allocating Memory First-Fit:
The free/busy list of tasks is maintained using this strategy, which maintains low-ordered to high-ordered memory organization. This method assigns the first work the first memory space that is greater than or equal to its size. Instead of looking for a suitable partition, the operating system simply assigns the task to the closest memory partition that is large enough.

explain the variety of transforms that are used to convert from object coordinates to 2d screen coordinates
In computer graphics, 2D transformation is the process of changing and repositioning the already-existing visuals in two dimensions. There are three primary rigid transformations: reflections, rotations, and translations. Transformations aid in changing an object's location, size, orientation, shape, and other attributes.
Transformations come in a variety of forms, including translation, rotation, scaling up or down, and shearing. A transformation is referred to as a 2D transformation when it occurs on a 2D plane. The object coordinates that we used to define the object must be converted into the world coordinate system that we are using for the scene before we can place it there. Our required change is referred to as a modeling transformation. When a figure is translated, it is moved in any direction. Flipping a figure over a line is called reflection. Rotation is the process of turning a figure a specific amount around a point. When we dilate a figure, we increase or decrease its size.
