Answer:
Step-by-step explanation:
81
=
3
4
and
27
=
3
3
, so this equation can also be written as
3
4
x
=
3
3
(
x
+
2
)
=
3
3
x
+
6
.
Since the bases are now the same, we can equate exponents to get
4
x
=
3
x
+
6
so that
x
=
6
(technically this equating of exponents requires the fact that exponential functions (with base not equal to 1) are one-to-one functions).

Answer: $2394.43
explanation: use equation A=Pe^rt. A=2000e^(0.03x6). A=2394.43
Because a beach volleyball is a sphere, so the volume formula is V= 4pi r^3/r
so the answer would be <span>24,429.024 </span>
