Answer:

Q.2: 39, Q.3: 20 cups

Step-by-step explanation:

Q.2 Dog/Cat = 2/3

when Dog = 26,

26/cat = 2/3

cat = 26 x 3 / 2 = 39

Q.3 Sugar/Flour = 3/5

when sugar = 12 cups,

12/Flour = 3/5

Flour = 12 x 5 / 3 = 20 cups

I have 20 books. Some are English and some are French. If 15 books are French, what fraction of books are in English?

allsm [11]

15/20 are French so 5/20 are English
Simplified that’s 1/4
Only applies if all the books are either English or French

Question 5: prove that it’s =0

Answer:

Proof in explanation.

Step-by-step explanation:

I'm going to attempt this by squeeze theorem.

We know that $\cos(\frac{2}{x})$ is a variable number between -1 and 1 (inclusive).

This means that $-1 \le \cos(\frac{2}{x}) \le 1$ .

$x^4 \ge 0$ for all value $x$ . So if we multiply all sides of our inequality by this, it will not effect the direction of the inequalities.

$-x^4 \le x^4 \cos(\frac{2}{x}) \le x^4$

By squeeze theorem, if $-x^4 \le x^4 \cos(\frac{2}{x}) \le x^4$

and $\lim_{x \rightarrow 0}-x^4=\lim_{x \rightarrow 0}x^4=L$ , then we can also conclude that $\im_{x \rightarrow} x^4\cos(\frac{2}{x})=L$ .

So we can actually evaluate the "if" limits pretty easily since both are continuous and exist at $x=0$ .

$\lim_{x \rightarrow 0}x^4=0^4=0$

$\lim_{x \rightarrow 0}-x^4=-0^4=-0=0$ .

We can finally conclude that $\lim_{\rightarrow 0}x^4\cos(\frac{2}{x})=0$ by squeeze theorem.

Some people call this sandwich theorem.
