I'm going to take a guess.
A 2-D object must have at least three sides (a triangle)
A 3-D object must have at least four sides (a triangular pyramid)
I'm going to guess that a 4-D object must have at least 5 sides, if the pattern holds...
4d is time...any moving object is 4d
3c - 4d = 6d + 4c Subtract 4c from both sides: -c - 4d = 6d Add 4d to both sides: -c = 10d or c = - 10d
no
It is a linear equation in one unknown, d.
A 4D object refers to an object with four dimensions, typically represented mathematically using four coordinates. In physics, time is often considered the fourth dimension alongside the three spatial dimensions. Visualizing or understanding 4D objects can be challenging because we are limited to perceiving three spatial dimensions.
We can think time as a 4D object, but we cannot visualize so easily a 4D object. But surely we know that a 4D object cannot live inside the 4D space, it will live in the 5th dimension space. We know that we can calculate the hyper-volumes by using integration (in our case) over a R4 domain which is not so easy to be visualize also. For example by hand we can construct a R3domain by using the xyz-coordinate system.
It depends on the context. It could mean 4 times d, or it could mean 4D - four-dimensional.
5+3 = 4d 4d = 8 Divide both sides by 4 to find the value of d: d = 2
That cannot be described as it is a 4D object. It can only be defined mathematically.
not yet, but with technological advancements, there could be.
The 4th dimension is commonly regarded as time. So a 4D cube could be considered a 3D cube as it exists over time.
8 - 4d = 12-4d = 4d = -1
