Jim read 24 pages in 40 minutes on Tuesday and 18 pages in 24 minutes on Wednesday. Are the ratios of pages read to minutes on T

IRISSAK [1]

Answer: Not proportional

Step-by-step explanation:

Ratio of pages read by Jim on Tuesday to minutes = $\frac{24}{40}=\frac{3}{5}=3:5$

Ratio of pages read by Jim on Wednesday to minutes = $\frac{18}{24}=\frac{3}{4}=3:4$

But $\frac{3}{5}\neq \frac{3}{4}$

Therefore, the ratios of pages read to minutes on Tuesday and Wednesday are not proportional.

Which is the inverse of the function f(x) = x2 − 4?

Rudiy27

The function is not one-to-one function, hence the inverse doesn't exist for the whole domain of the function. But if we restrict the domain to $x\in(-\infty,0]$ or $x\in[0,\infty)$ , then we can give the inverse.

$f(x)=x^2-4\\\\y=x^2-4\\\\x^2=y+4\\\\x=\sqrt{y+4} \vee x=-\sqrt{y+4}\\\\f^{-1}(x)=\sqrt{x+4}\vee f^{-1}(x)=-\sqrt{x+4}$

So, when $D_{f(x)}:x\in(-\infty,0]$ , the inverse is $f^{-1}(x)=-\sqrt{x+4}$ and when $D_{f(x)}:x\in[0,\infty)$ , the inverse is $f^{-1}(x)=\sqrt{x+4}$ .
