Find two complex numbers that have a sum of 10i, a difference of -4 and a product of -29

HACTEHA [7]

Let these two numbers be $z$ and $w$ . Their sum is $10i$ , their difference is -4, and their product is -29:

$z+w=10i$

$z-w=-4$

$zw=-29$

Add the first two equations together to eliminate $w$ :

$(z+w)+(z-w)=10i-4\implies 2z=-4+10i\implies z=-2+5i$

Then

$w=10i-z\implies w=10i-(-2+5i)=2+5i$

Just to confirm this is correct, check their product:

$(-2+5i)(2+5i)=-4+25i^2=-4-25=-29$

A book with 650 pages has 3 pages with diagrams.

Mrac [35]

The pages that have diagrams is an illustration of proportions

0.46% pages have diagrams

<h3>How to determine the percentage</h3>

The given parameters are:

Total = 650 pages

Diagrams = 3 pages

The percentage of page that has diagram is then calculated as:

$Diagram\% = \frac{Diagrams}{Total} * 100\%$

So, we have:

$Diagram\% = \frac{3}{650} * 100\%$

Evaluate the product

$Diagram\% = \frac{300}{650} \%$

Divide

$Diagram\% = 0.46 \%$

Hence, 0.46% pages have diagrams
