Find the values of x and y<br><br> 1-2i/ 2+i + 4-i/3+2i = x+iy
lina2011 [118]

Answer:

x=\frac{10}{13} and y=-\frac{24}{13}

Step-by-step explanation:

The given complex number equation is:

\frac{1-2i}{2+i}+\frac{4-i}{3+2i}=x+yi

We simplify the LHS and compare with the RHS

We collect LCD on the left to get:

\frac{(1-2i)(3+2i)+(4-i)(2+i)}{(2+i)(3+2i)}=x+yi

\frac{3+2i-6i+4+8+4i-2i+1}{6+4i+3i-2}=x+yi

Simplify to get:

\frac{16-2i}{4+7i}=x+yi

Rationalize the LHS:

\frac{(16-2i)(4-7i)}{(4+7i)(4-7i)}=x+yi

Expand the numerator using the distributive property and the denominator using difference  of two squares.

\frac{64-112i-8i-14}{16+49}=x+yi

Simplify to get:

\frac{50-120i}{65}=x+yi

\frac{10-24i}{13}=x+yi

\frac{10}{13}-\frac{24}{13}i=x+yi

By comparing real parts and imaginary parts; we have;

x=\frac{10}{13} and y=-\frac{24}{13}

LOOK HOW MANY POINTS!!! PLEASE HELP ASAP A cell phone company tests 75 cell phones and finds that 3 of them have defects. Out of
kozerog [31]

Answer:

Out of 450 phones 18 of them will have a defect.

Step-by-step explanation:

As we know that out of 75 phones 3 of them will have a defect, this means that we are able to calculate how many defects there will be from 450 phones. You can do this by first dividing 450 by 75, this gives you 6. This means that 75 will go into 450 6 times.

From this we are able to work out the number that will have defects. This is because we know that 75 goes into 450 6 times and that for each 75 phones there will be 3 defects. So to work out the number of phones out of 450 that would be defects you would simply multiply 3 by 6, this gives you 18. This shows that out of 450 phones 18 of them will have a defect.

1) Divide 450 by 75.

450/75=6

2) Multiply 6 by 3.

6*3=18
