Let z =8(cos (pi/3) + i sin (pi/3)) and w= 3(cos(pi/6) +isin (pi/6)

Which statement describes the geometric construction of the product zw on the complex plane?

Answers

Answer 1
Answer:

No statements are given...

At the very least, we can compute the product zw by multiplying the moduli and adding the arguments. That is, if

z = 8 (cos(π/3) + i sin(π/3))

w = 3 (cos(π/6) + i sin(π/6))

then their product is

zw = 8•3 (cos(π/3 + π/6) + i sin(π/3 + π/6))

zw = 24 (cos(π/2) + i sin(π/2))

zw = 24i

Answer 2
Answer:

The product of complex numbers z and w results in a point that is situated along the positive y-axis in the complex plane, being 24 units away from the origin.

In complex numbers, the geometric meaning of a product of two numbers, here zw, corresponds to the multiplication of the moduli and the addition of the arguments of the two numbers.

Here, z = 8(cos (pi/3) + i sin (pi/3)) and w = 3(cos(pi/6) + i sin (pi/6)), so the modulus of zw is 3*8 = 24.

The argument is the sum of the arguments (pi/3 + pi/6) which is pi/2. Hence, the product can be rewritten as zw = 24(cos(pi/2) + i sin(pi/2)). This geometric construction will situate the point along the positive y-axis in the complex plane, with a distance of 24 units from the origin.

Answer:

28 m

Step-by-step explanation:

1 m=100 cm

?=200 cm ...

200 cm=2m

area=lw

A=14 m*2 m

A=28 m

Answer:

28

Step-by-step explanation:

200 cm = 2m

Area = length × Width

So..

Area = 14×2

= 28

If y = x - 6 were changed to y = x + 8, how would the graph of the new function compare with the first one?

Answers

The graph of the new function compared with the first one is the graph would be shifted upward.

What is the equation?

In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

The given equations are;

y = x - 6

y = x + 8

To compare the equation substitute the value of x = 0 and solving for the value of y.

y = x - 6

x = 0

y = 0 -6

y = -6

And y = x + 8

y = 0 + 8

y = 8

So the function would be shifted upward.

Hence, the graph of the new function compared with the first one is the graph would be shifted upward.

The first one would have a y-intercept of (0,-6) and the second one would have a y-intercept of (0,8) and x (the slope) would still be the same.
y=x-6 would have points with (0,-6) (2,-4) (4,-2) (6,0)
y=x+8 would have points with (0,8) (-2,6) (-4,4) (-6,2)
In other words shifted up. Hope this helps!
