(-2/5)7÷(-2/5)5=????

Harman [31]

Answer:

$\frac{4}{25}$

Step-by-step explanation:

Using the rule of exponents

$a^{m}$ ÷ $a^{n}$ ⇔ $a^{(m-n)}$

Given

$-2/5)^{7}$ ÷ $(-2/5)^{5}$

= $(-2/5)^{(7-5)}$

= $(-2/5)^{2}$

= - $\frac{2}{5}$ × - $\frac{2}{5}$ = $\frac{4}{25}$

if k is a half-plane determined by QR, then for every real number 0 < x < or = to 180, there is exactly one ray, QQP, that

zloy xaker [14]

Let me start from the meaning of half plane.you must have learned that there are two axes X and Y axes which includes positive X axes and negative X axes and there is positive Y axes and negative y axes. So there are four quadrants which i have explained in the figure. I have explained the meaning of Half plane in the Diagram also. Half plane=Figure obtained by covering any two adjacent regions of the coordinate axes.So we get four half planes.

Now your question is k is a half plane determined by QR, such that 0<x≤180 and there is exactly one ray QRP that lies in k

So, $0< \angle PQR \leq 180^\cir{0}$
