Please help me with the below question.
tresset_1 [31]

We have the following three conclusions about the <em>piecewise</em> function evaluated at x = 14.75:

  1. \lim_{t \to 14.75^{-}} f(t) = 66.
  2. \lim_{t \to 14.75^{+}} f(t) = 10.
  3. \lim_{t \to 14.75} f(t) does not exist as \lim_{t \to 14.75^{-}} f(t) \ne  \lim_{t \to 14.75^{+}} f(t).

<h3>How to determinate the limit in a piecewise function</h3>

In a <em>piecewise</em> function, the limit for a given value exists when the two <em>lateral</em> limits are the same and, thus, continuity is guaranteed. Otherwise, the limit does not exist.  

According to the definition of <em>lateral</em> limit and by observing carefully the figure, we have the following conclusions:

  1. \lim_{t \to 14.75^{-}} f(t) = 66.
  2. \lim_{t \to 14.75^{+}} f(t) = 10.
  3. \lim_{t \to 14.75} f(t) does not exist as \lim_{t \to 14.75^{-}} f(t) \ne  \lim_{t \to 14.75^{+}} f(t).

You had a bag of fruit snacks that you shared with 4 friends. Each of you got at least 2 fruit snacks. The inequality x/ 5 ≥ 2 m
podryga [215]

Answer:

10 fruit snacks were in the packet.

Step-by-step explanation:

lets look at the numbers, we have 5 and 2. your answer is 8 because 5x2=10

it would basiclly be the same as dividing. say your question was you have a packet of fruit snacks, there are 10 fruit snacks in the packet and 4 friends and you how many did you each have the answer would be 2.

your probably wondering why its 5 and not 4 well the question says... You had a bag of fruit snacks that you shared with 4 friends, it says you shared so that is why its 5 and not 4.

HOPE THIS HELPS!!!!!! :)
