30 - 29 = 1 for the first one.
Answer:
-1/9
Step-by-step explanation:

For simplicity, let's multiply top and bottom by 3x:

Factor out a -1:

Divide top and bottom by x−3:

Evaluate the limit:

It's important to note that the function doesn't exist at x = 3. As x <em>approaches</em> 3, the function <em>approaches</em> -1/9.
Answer:
0.84
Step-by-step explanation:
hope this helps, brainliest appreciated!
Realize the tangent function has a period of 180°, so when your calculator (or memory) tells you
.. θ = arctan(-1)
.. θ = -45°
you can translate that value into the desired range by adding multiples of 180° to get the two solutions ...
.. θ = 135°
.. θ = 315°
Answer:
16 + 2n
Step-by-step explanation:
n + n is twice of a number, but 2n is simplified. "16 increased by" just represent addition
