To which subset of real numbers does the number 1/4 belong?

2 answers:

8 0

It belongs in rational numbers because if you converted it into a decimal, it would only be .25. If it was a number like pi, then it would be an irrational number because there is almost no end to it.

Answer:

289

Step-by-step explanation:

We don't need $g$ at all for this.

We will need to know $f(4)$ before continuing...

$f(4)$ can be found by replacing $x$ in $f(x)=x^2+1$ with $4$ :

$f(4)=4^2+1$

$f(4)=16+1$

$f(4)=17$

-------------------

Now let's find $[f(4)]^2$ :

$[f(4)]^2$

$[17]^2$

$17(17)$

$289$

1. add negative fraction with positive fraction

jok3333 [9.3K]

Given parameters:

1. $-\frac{7}{8} + \frac{1}{4}$

$-\frac{7}{8} + \frac{1}{4}$ ; find the LCM = 8

= $\frac{-7 + 2 }{8}$

= $\frac{-5}{8}$

2. $-\frac{12}{5} + 15.3$

Make the fraction decimal;

$-\frac{12}{5}$ = -2.4

So;

-2.4 + 15.3 = 12.9
