Find the area of the following shape. You must show all work to receive credit.

statuscvo [17]

Answer:

8 unit ^2 or 8cm^2

Step-by-step explanation:

area 1

1/2 ( 3 x 3 ) = 4.5 unit ^2

area 2 we split the triangle into half

= 1/2 ( 2 x 2) = 2 unit ^2

we know the other half is also 2 unit ^2 but we add then subtract

1/2 (1 x 1) = 0.5^2

To get

4.5 + 2+ 2 - ( 0.5) = 8 unit ^2

What is the product of z1 and its conjugate?

Tems11 [23]

From the plot, we see that $z_1=-4-3i$ . Its conjugate would be $\bar{z_1}=-4+3i$ , so that the product of the two is

$z_1\bar{z_1}=(-4-3i)(-4+3i)=16-9i^2=16+9=25$

More generally, note that if $z=x+yi$ , then

$z\bar z=(x+yi)(x-yi)=x^2+y^2=|z|^2$
