Answer: not sure
Step-by-step explanation:
What does x represent?
If you want to round to the nearest thousand, you cannot look at the thousands place to round. You will have to look at the number in the hundreds place. The rules of rounding are
<em>5 and above-round up. Example-2743. 7 is greater than 5, so 2743 rounded to the nearest thousand is 3000.
</em>
<em>4 and below-round down. Example-4390. Three is less than 5, so 4390 rounded to the nearest thousand is 4000.
</em>
Apply these rules to your problem. 8 is greater than 5. So we will round up. You get 5000.<em>

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:
x ≥ -12
