Answer:

  a) <8.356, 9.959>

  b) <-0.605, -1.663>

  c) <-5.023, 2.9>

Step-by-step explanation:

Many calculators can perform polar ⇔ rectangular conversion. Attached is the result from one of them. Of course, you can also program a spreadsheet to do it. (The ATAN2( ) function is useful for finding the correct angle.)

If you want to do these calculations by hand, the conversion is ...

  <r, θ> ⇒ <r·cos(θ), r·sin(θ)>

In the attached, the rectangular coordinates are shown as complex numbers. The imaginary component is the y-component of the vector.

Answer:

n = 2 or n = 3/2 thus A. is the Answer

Step-by-step explanation:

Solve for n:

2 n^2 - 7 n + 6 = 0

The left hand side factors into a product with two terms:

(n - 2) (2 n - 3) = 0

Split into two equations:

n - 2 = 0 or 2 n - 3 = 0

Add 2 to both sides:

n = 2 or 2 n - 3 = 0

Add 3 to both sides:

n = 2 or 2 n = 3

Divide both sides by 2:

Answer: n = 2 or n = 3/2

I think the answer is 80 because I’m point 2 it’s is 40 and in point 3 is 60 and in point 5 is 100 so I am guessing each goes by 20 so what is between 60 and 100 if you can’t by 20s would be 80 I don’t know if I am correct tho

find the width of a rectangular prism if the volume is 165,000 mm3 the length is 100mm and the height is 55 mm​
zepelin [54]

Answer:

Width is 30mm

Step-by-step explanation:

Volume = L×W×H

Volume= 165,000 mm³

Length= 100mm

Height= 55mm

Width= ?

L×H

100mm×55mm= 5500mm

volume ÷ L×W

165,000÷5500=30

width= 30mm

L×W×H=V

100×55×30=165000
