Answer:

The constant of variation for the direct variation is 2.

Step-by-step explanation:

The given line passes through the origin (0, 0) and (3, 6)

The constant of variation for the direct variation means the slope of the line.

The slope can be calculated from the the two coordinates that are on the lines, i.e (0, 0) and (3, 6)

x₁ = 0

y₁ = 0

x₂ = 3

y₂ = 6

Putting the values,

Therefore, the constant of variation for the direct variation is 2.

Two complex numbers are given byz1= 3 +j4 andz2= 2 +j3. Determine in both polar andCartesian forms
Marat540 [252]

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)

Shaniqua is 25% less money than her older sister Jennifer Shaniqua has $180 how much does Jennifer have
Kazeer [188]

Answer:

Jennifer have $240.

Step-by-step explanation:

It is given that Shaniqua is 25% less money than her older sister Jennifer.

Let Jennifer have x dollars.

Shaniqua have = (x - 25% of x) dollars

It is given that Shaniqua has $180.

x-\dfrac{25}{100}\times x=180

x-0.25x=180

0.75x=180

Divide both sides by 0.75.

x=\dfrac{180}{0.75}

x=240

Therefore, Jennifer have $240.
