Answer:
Step-by-step explanation:
Dimensions: 1 x 1 x 36 or 12 x 3 x 1 or 9 x 4 x 1 or 9 x 2 x 2
We will solve for
x
using the very basic properties of natural logarithms. I'll illustrate it below.
Explanation:
We have,
ln
(
x
−
2
)
2
=
6
Using the property,
ln
m
n
=
n
ln
m
,
We have,
ln
(
x
−
2
)
2
=
6
⇒
2
ln
(
x
−
2
)
=
6
⇒
ln
(
x
−
2
)
=
3
⇒
x
−
2
=
e
3
In the last step, we used the concept of inverse of the natural logarithms,
ln
m
=
n
⇒
m
=
e
n
Thus,
x
=
e
3
+
2
Where e is the base of natural logarithms.

Answer:
600
Step-by-step explanation:
The circumference of a tire is the distance around it. The distance around these tires is 1 m. Since the tires revolve 15 times per second, this means every second the tires travel 15 m. This means that in 40 seconds, the tires travel15(40) = 600 m.
15 x 40 = 600
Geometric progression, first term 5, common ratio 3.
