True
Explanation:
In order to apply and experience the beauty of mathematics, a good comprehension of the discipline is required.
In fact, this is general to anything in life. To fully maximize any potential, one must be well groomed about what exactly that thing is.
Mathematics is a science that deals with the logic of shapes and numbers. There are different branches of this discipline with real world adoption.
The tenets of mathematics cuts across business, science, arts, e.t.c.

Yes, the answer is in fact C. All of the above.
Variable stars are stars that change in brightness. The change could be due to the physical change in the star or it could also be caused when another star crosses another, or in other words eclipse.
Answer:
Explanation:
Given that,
Initial Angular velocity w=500rpm
Converting from rpm to rad/s
1rev =2πrad
1minutes =60secs
500rpm=500rev/mins
w = 500×2π/60
wi=52.36rad/s
The final angular velocity wf=0rad/s
Time to stop is t=2.6sec
We want to find angular acceleration α
Using the equation of angular motion
wf = wi + αt.
0 = 52.36 + 2.6α
-52.36=2.6α
α = -52.36/2.6
α = -20.14rad/s²
The angular acceleration is negative because it is decelerating.
Then, α=20.14rad/s²
