Find the quotient and express it in the simplest form

pychu [463]

2i(4+5i)(4-5i) =82i
4+i nothing more can be done it is at simplest form

so $\frac{82i}{4+i}$ = $\frac{82}{17} + \frac{328}{17} i$

so your answer is $\frac{82}{17} + \frac{328}{17} i$

Erik and Nita are playing a game with numbers. In the game, they each think of a random number from zero to 20. If the differenc

Mademuasel [1]

Let X is the random number Erik thinks of, and Y is the random number Nita thinks of.
Both X and Y are in the range from 0 to 20.
X<=20
Y<=20
If the difference between their two numbers is less than 10, then Erik wins.
The difference between the two numbers can be written X-Y, or Y-X depending on which number (X or Y) is greater. But we do not know that. In order not to get negative value, we calculate absolute value of X-Y, written |X-Y| which will give positive value whether X is greater than Y or not.
If |X-Y|<10 Erik wins.
If the difference between their two numbers is greater than 10, then Nita wins.
If |X-Y|>10 Nita Wins

Answer:

Length of side of rhombus is $x=\frac{ab}{a+b}$

Step-by-step explanation:

Given Rhombus ADEF is inscribed into a triangle ABC so that they share angle A and the vertex E lies on the side BC. We have to find the length of side of rhombus.

It is also given that AB=a and AC=b

Let side of rhombus is x.

In ΔCEF and ΔCBA

∠CEF=∠CBA (∵Corresponding angles)

∠CFE=∠CAB (∵Corresponding angles)

By AA similarity rule, ΔCEF~ΔCBA

∴ their sides are in proportion

$\frac{EF}{AB}=\frac{CF}{AC}$
