8 + 4(x - 15) = 42
8 + 4x - 60 = 42
4x - 52 = 42
+ 52 + 52
4x = 94
/4 /4
x = 23.5

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.

konstantin123 [22]

Answer:

Equation of the line with m=3  and b = 8.25 is y=3 x+8.25

Step-by-step explanation:

m = 3 and b = 8.25

To get equation of line we use y=mx+b

Where m represents the slope = 3

b represents the y intercept = 8.25

Plug in the values in y=mx+b

y= 3x + 8.25

Equation of the line with m=3  and b = 8.25 is y=3 x+8.25
