Answer:
b
Step-by-step explanation:
x=2
<span>1.5 rev/s
Since angular momentum is conserved, the product of the moment of inertia and the rotational rate will remain a constant. So, assuming X as the desired rate of rotation we have:
X * 2.9 = 4.8 * 0.90
Now solve for X
X * 2.9 = 4.8 * 0.90
X * 2.9 = 4.32
X = 1.489655172
So when her arms and one leg go outward, her rotation slows to 1.489 rev/s. Rounding to 2 significant figures, gives 1.5 rev/s.</span>
Answer:
the number is 5
Step-by-step explanation:
in an equation it will be 4x-3=17
4x=17+3
4x=20
x=20/4
x=5
hope this helps plzz mark me brainliest
I think the answer is y = .38
