Which two complex numbers when added together and written in standard form equal 10-3i?

dedylja [7]

Answer:

A -3 − 4i C 13 + i

Step-by-step explanation:

We add the real part and the imaginary part separately.

Adding A and C will give us 10 - 3i:

-3 - 4i + 13 + i

= -3 + 13 - 4i + i

= 10 - 3i.

area of semi-circle= ½πr²

½π(3)²

= 9/2π

area of isosceles trapezoid= ½(b1+b2)h

½(15+6)8

=84

area of figure= 9/2π +84

Given the function: f(x) = 2|x-2| + 3 Describe how the function is transformed A. Moves to the right by 2 and up by 3 units B. M

Ivahew [28]

In the general form:

$f(x)=A|x-B|+C$

$A$ is a stretch
$B$ is the horizontal shift
$C$ is the vertical shift

So in your case:

$A=2$
$B=2$
$C=3$

So you have a stretch by 2
A horizontal shift right 2
And a vertical shift up 3

Please include the steps that took you to get your answer. I am very confused on what to do with the 1/2.

Juliette [100K]

First let's review how to expand this!

(ax+b)^2=a^2*x^2+2abx+a^2

In this case

(2x^2+1/2)^2=2^2*x^2+2*1/2*2x+(1/2)^2

=4x^2+2x+1/4

Done!
