Answer:

Step-by-step explanation:

We're looking for a number (x) that's less than 44

We can represent it by simply using the less sign, so x < 44

wel

f(0) = $\sqrt{2}$ · $\sqrt{2^{2(0) - 1}}$

= $\sqrt{2}$ · $\sqrt{2^{0 - 1}}$

= $\sqrt{2}$ · $\sqrt{2^{- 1}}$

= $\sqrt{2}$ · $\frac{1}{\sqrt{2}}$

= $\frac{\sqrt{2}}{\sqrt{2}}$

= 1

Find the distance between<br> 2-3i<br> And<br> 9+21i

Goryan [66]

2 - 3i is just another of writing (2, -3) in the cartesian plane, the 2-3i however is using the "imaginary axis" for the imaginary plane, is all however the imaginary axis is simply the equivalent of the y-axis. Likewise 9+21i is just (9,21), so let's just use the distance formula.

$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{2}~,~\stackrel{y_1}{-3})\qquad (\stackrel{x_2}{9}~,~\stackrel{y_2}{21})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ d=\sqrt{[9-2]^2+[21-(-3)]^2}\implies d=\sqrt{(9-2)^2+(21+3)^2} \\\\\\ d=\sqrt{7^2+24^2}\implies d=\sqrt{49+576}\implies d=\sqrt{625}\implies d=25$
