Question

HELP ASAP PLEASE!!!!

Answer 1

Answer:

1: negative square root of 18 (-4.2)

2: negative square root of 7 (-2.6)

3: pi/2 (1.57)

4: square root of 15 (3.9)

some are approximate calculations, but you only need the order of from smallest to largest number

Answer 2

Simplify numbers to layman terms.

$\frac{\pi}{2}$ will be a little more than $\frac{3}{2}$, since $\pi$ is 3.14.

$-\sqrt{18}$ will be a little less than -4, since $-\sqrt{18}$.

$\sqrt{18}$ will be a little more than 4, since $\sqrt{18}>\sqrt{16}$

$-\sqrt{7}$ will be a little less than -2, since $-\sqrt{7}$

Now we can order them.

$-\sqrt{18},-\sqrt{7},\frac{\pi}{2},\sqrt{18}$

Hope this helps.

頑張って!
