Answer:

$\bold{2+\frac{5i}3-2i=2-\frac{1}3i}$

or if you mean (2 + 5i)/(3 - 2i) at complex numbers

$\bold{\dfrac{2+5i}{3-2i}=\dfrac{-4+19i}{13}=-\frac{4}{13}+1\frac{6}{13}\,i}$ .

Step-by-step explanation:

$\bold{2+\frac{5i}3-2i=2+\frac{5i}3-\frac{6i}3=2-\frac{1}3i}$

But I think you mean: (2 + 5i)/(3 - 2i) and complex numbers.

Then:

$\dfrac{2+5i}{3-2i}=\dfrac{(2+5i)(3+2i)}{(3-2i)(3+2i)}=\dfrac{6+4i+15i+10i^2}{9+6i-6i-4i^2}=\dfrac{6+19i-10}{9+4}=\dfrac{-4+19i}{13}$

Which statements are correct interpretations of this graph?

kupik [55]

Answer:

B. 3 pages are edited every five minutes

D. 6/10 of a page is edited per minute

Step by step:

Three pages are done at an interval of five minutes.

Six tenths of a page is done every minute

0.6 * 5 = 3 per five minutes

The other statements are false.

12/3 = 4, four done every minute, really?

5 pages are edited every three minutes.

This would disprove statement B.

And does not align with the graph.

Hope this helps.
