Convert the polar representation of this complex number into its standard form: z=4(cos5pi/6 + i sin 5pi/6)
The complex number z = 4(cos(5pi/6) + isin(5pi/6)) is given as z = -3.464 + 2i in standard form
What is a complex number?Complex numbers are the numbers which is in the form of:
a + ib where, a,b are real numbers and 'i' is an imaginary number.
The complex number can also be represented in polar form as:
z = r(cosФ + isinФ)
Given the complex number:
z=4(cos(5pi/6) + isin(5pi/6)), hence converting to standard form gives:
z = -3.464 + 2i
The complex number z = 4(cos(5pi/6) + isin(5pi/6)) is given as z = -3.464 + 2i in standard form

x = 4
2x + 4y = 36
Step-by-step explanation:
2x + 4y = 36
2 × 4 + 4y = 36
8 + 4y = 36
4y = 36 - 8
4y = 28
y = 28 ÷ 4

Answer:
x = 3 oz of seeds
y = 7 oz of seeds
Step-by-step explanation:
1. x + y = 10 oz (total amount of snack mix in ounces; oz)
2. $1.50x + $2.50y = $22 (how much the seeds and dried fruit costs)
3. Solve the system of equations using algebra.
$1.50 x + $1.50y = $15
$1.50 x + $2.50y = $22
There are $1.50x's in both of the equations, so cancel them out.
Subtract $2.50y by $1.50y and $22 by $15. y = 7
4. Plug in the y value in one of the equations.
x + 7 = 10; x = 3

The length of a box is twice the width and thrice the height. If the volume of the box is 288 m then find the dimensions of the box
Answer:
length = 12 mwidth = 6 mheight = 4 mStep-by-step explanation:
Let the height be x.
Length is 3 thrice the height, so length ⇒ 3xLength is twice the width, so width ⇒ 3x/2We know the formula for volume of the box.
V = lwhV = (3x)(3x/2)(x)288 = 9x³/29x³ = 576x³ = 64x = 4 mDimensions
