Answer:
<em>There are 20345.556... feet in 6.2 km.</em>
Step-by-step explanation:
Given that, 1 mile = 1.609 km and 1 mile = 5280 ft.
<u>That means we can say</u>, 1.609 km = 5280 ft.
So, 1 km = 
Now, for converting 6.2 km into feet, we will <u>just multiply 6.2 by 3281.541... ft</u>.
Thus, 6.2 km = 
So, there are 20345.556... feet in 6.2 km.
Answer:

Step-by-step explanation:
we are given a derivative

and said to figure out the first derivative
to do so
recall chain rule:

so we get

rewrite the derivative using the chain rule:

use square root derivative rule to simplify:

now we need to again use chain rule composite function derivative to simplify
where we'll take a new function n so we won't mess up two g's and we'll take 2x as n
use composite function derivative to simplify:

use derivative formula to simplify derivatives:

substitute the value of n:

substitute the value of g:

now we need our trigonometric skills to simplify
rewrite cot and csc:

simplify multiplication:

simplify multiplication:

Answer:
213 meters squared
Step-by-step explanation:
The surface area of a rectangular prism is found using the formula A=2(wl+hl+hw). Here substitute l = 6, w = 3.5 and h = 9.
A = 2((3.5*6) + (9*6) + (3.5*9))
A = 2(21 + 54 + 31.5)
A = 2(106.5)
A = 213
