Answer:
ln (27 x²)
Step-by-step explanation:
Given in the question an expression
3 ln 3 + 2 ln x
Step1
Apply power rule
ln 3³ + ln x²
Step2
Apply multiplication rule
ln (3³ . x²)
3³ = 27
so
ln (27x²)

Answer:
I got 45
Step-by-step explanation:
so I did the triangle first I did 5 times 6 divided by 2 and got 15 then I did 5 times 6 and got 30 then I added the 30 and 15 together.
Answer:
4.4 x 10^9
Step-by-step explanation:
(8.8 x 10^6)(5 x 10^2)
Multiply the 8.8 and 5
8.8 x 5 = 44
Add the powers (don't touch the 10s)
6 + 2 = 8
Right now we have: 44 x 10^8 but this isn't in scientific notation. The decimal must have a SINGLE digit to the left of it; no more no less.
Move the decimal over one place to the left.
44 turns into 4.4
This action adds another power
8 + 1 = 9
Thus our final answer is: 4.4 x 10^9
Christopher's distance from his starting point is 3.6 km
Since Christopher initially walks South 5 km and then walks on a bearing of of 036º until he is due east of his starting point, His distance South, his distance from his starting point and his distance from his 036º bearing, all form a right-angled triangle with opposite side to the angle 036º, as his distance from his starting point, x and the adjacent side to the angle 036º, as his distance 5 km south.
Since we have both the opposite and adjacent sides of a right-angled triangle,
From trigonometric ratios,
tanФ = opposite/adjacent
tanФ = x/5 km
Now Ф = 036º
So, tan36º = x/5km
x = 5 km(tan36º)
x = 5 km (0.7265)
x = 3.633 km
x ≅ 3.6 km to 1 decimal place.
So, Christopher's distance from his starting point is 3.6 km.
