Two complex numbers are given byz1= 3 +j4 andz2= 2 +j3. Determine in both polar andCartesian forms

Mathematics

Answer:

Cartesian

z₁= 3 +4*j

z₂= 2 +3*j

Polar

z₁=5 * e^ (0.927*j)

z₁=√13 * e^ (0.982*j)

Step-by-step explanation:

for the complex numbers z the cartesian form of is

z= x + y*j

then

1) z₁= 3 +4*j (cartesian form)

2) z₂= 2 +3*j (cartesian form)

the polar form is

z= r* e^jθ

where

r= √(x²+y²) → r₁ = √(3²+4²) = 5 ,  r₂ = √(2²+3²) = √13

and

θ = tan⁻¹ (y/x)  → θ₁  = tan⁻¹ (4/3)= 0.927 rad , θ₂  = tan⁻¹ (3/2)= 0.982 rad

then

z₁=5 * e^ (0.927*j)

z₁=√13 * e^ (0.982*j)

Discuss the differences between the measurement of the surface area and the measurement of the volume of a right rectangular pri
yKpoI14uk [10]
Given: 
Right Rectangular Prism.
It has its length, width, and height.

Surface area of a right rectangular prism has this formula:
SA = 2 (wl + hl + hw)

Volume of a right rectangular prism has this formula
V = whl

Formula of Surface Area is different from Volume.

Surface area measures the area the whole rectangular prism surface. It computes for the area of all 6 faces that a right rectangular prism has.

Volume measures the area within the rectangular prism. It is the space that is enclosed within the rectangular prism.

Solve the equation for the bold variable (h)
Aleonysh [2.5K]

This is the formula for the surface area of a cylinder including the ends, like the total surface area of a can of peas.

S = 2·π·r² + 2·π·r · H

Divide each side by 2·π·r :

S/2·π·r = r + H

Subtract r from each side :

H = (S/2·π·r) - r

or

H = (S - 2·π·r²) / (2·π·r)

A square has a side length equal to 5x-3y inches. What is the area of this square
erastovalidia [21]

Answer:

D.

Step-by-step explanation:

The area is the product of 2 adjacent sides:

Area = (5x - 3y)(5x - 3y)     as the sides of a square are all equal.

= 5x(5x - 3y) - 3y(5x - 3y)

= 25x^2  - 15xy - 15xy + 9y^2

= 25x^2 - 30xy + 9y^2.

The image shows a ray of light bending at the boundary of a glass block. According to a law of optics, = n, where n is a constan
Salsk061 [2.6K]
The law of optics applicable in this scenario is the Snell's Law which states that the ratio of the index of refraction of two media is equal to the ratio of the sine of the angle of reflection and sine of the angle of refraction. In equation form:
n₁ / n₂ = sin b / sin a
