\text{Hello there! :)}

3. \sqrt{2} \\\\\text{4.  0}\\\\\text{5.  dne}

\text{To find the overall limit, they must approach the same y-value from each side:}

\\\\3.  \lim_{x \to \frac{\pi }{4} } 2sinx ={\sqrt{2}

\text{Therefore:}\\\\3.  \lim_{x \to \frac{\pi }{4} } f(x)= {\sqrt{2} }

\text{For this question, evaluate the limit from the RIGHT-HAND side:}\\\\4.   \lim_{x \to \pi +} f(x)\\\\ \text{Use the equation tanx to evaluate since it involves values greater than \pi:}\\\\

\lim_{x \to \pi +} tanx = 0\\\\\text{So:}\\\\ \lim_{x \to \pi +} f(x) = 0

5.  \\\\\text{Evaluate the overall limit. Make sure both sides approach the same y=value:}\\\\ \lim_{x \to \pi } 2cosx= -2\\\\ \lim_{x \to \pi } tanx = 0\\\\ \text{ Therefore:}\\ \lim_{x \to \pi } f(x) = dne \text{ (Does not exist})

Andre took 6 kicks and made 4 goals: 4 out of six. Tom wants to take more than 20 kicks and make a equivalent fraction to Andre.
Zanzabum

Answer:

Tom can either take 24 kicks and make 16 goals or 30 kicks and make 20 goals.

Step-by-step explanation:

Andre made 4 goals out of 6 kicks.

Tom wants to take more than 20 kicks and to make an equivalent fraction to Andre.

<u>Possibility 1:</u>

Let Tom makes 24 kicks.

To get 24, we need to multiply the denominator of Andre's fraction by 4.

So, \frac{4}{6} =\frac{16}{24}

Therefore, Tom can take 24 kicks and make 16 goals.


<u>Possibility 2:</u>

Let Tom makes 30 kicks.

To get 30, we need to multiply the denominator of Andre's fraction by 5.

So, \frac{4}{6} =\frac{20}{30}

Therefore, Tom can take 30 kicks and make 20 goals.
