Hello from MrBillDoesMath!
Answer:
1/ 91.4
Discussion:
Evaluate 1/ ( 3x^3 + 5.2y) when x = 3, y = 2.
1/ (3 (3)^3 + 5.2(2)) =
1/ ( 3 * 27 + 10.4) =
1/ ( 81 + 10.4) =
1/ (91.4) =
.0109 (approx)
Thank you,

Answer:
1767.1 inches cubed
Step-by-step explanation:
The volume of a ball, or a sphere, is:
, where r is the radius.
Here, the radius is r = 7.5. So, plug in this value: 
562.5 pi is about 1767.1 inches cubed.
Thus, the volume is 1767.1 inches cubed.
Hope this helps!
For this case we have that by definition of multiplication of powers of the same base, the same base is placed and the exponents are added:

So, we can rewrite the given expression as:

So, if
:
