Answer:
D) {112, 6, 24, 20, 44, 15, 29}
Step-by-step explanation:
Range is the largest number minus the smallest number in the set.
Below I have found the range of each of the following answers. Once you figure out the ranges, the largest one is your answer.
A) 44 - 8 = 34
B) 119 - 16 = 103
C) 31 - 9 = 22
D) 112 - 6 = 106
A. Factor the numerator as a difference of squares:
c. As
, the contribution of the terms of degree less than 2 becomes negligible, which means we can write
e. Let's first rewrite the root terms with rational exponents:
Next we rationalize the numerator and denominator. We do so by recalling
In particular,
so we have
For
and
, we can simplify the first term:
So our limit becomes
+2
-8-(-10
You can just add a plus in the middle
-8+(10=+2
