Determine the graph of the polar equation r=4/(1-1/2cosx(theta))
crimeas [40]

Answer:

  see below

Step-by-step explanation:

We assume you want the graph of ...

  r=\dfrac{4}{1-\frac{1}{2}\cos{(\theta)}}

A graphing calculator or spreadsheet is useful for this.

__

You know cos(θ) = cos(-θ), so the graph is symmetrical about the x-axis. You can evaluate the function at a few points to find the general outline.

  r at 0° = 8

  r at 30° ≈ 7.05

  r at 45° ≈ 6.19

  r at 60° ≈ 5.33

  r at 90° = 4

  r at 120° = 3.2

  r at 135° ≈ 2.96

  r at 150° ≈ 2.79

  r at 180° ≈ 2.67

Simplify each expression.
MrRa [10]
1)B -26-27x
steps :distribute ,-9 times 3 =-27 , -9 times 3x = -27x , now combine like terms :you have a 1 and a -27 ,1-27=-26,and you left with -27



2)D 11-49x
steps :distribute , positive 7 times 1= 7 and then positive 7 times negative 7x =-49, now combine like terms ,since you have a positive 4 combine it with positive 7 which is 11 and finally put it together with -49x which it would look like 11-49x

Create an equation to solve for x, then solve to find its value.
Amanda [17]

Answer:

Equation: x + 16 + 13 + x = 21 ; x = -4

Step-by-step explanation:

x + 16 + 13 + x = 21 (Given)

2x + 29 = 21 (Added like terms)

2x = -8 (Subtracted 29 on both sides)

x = -4 (Divided 2 on both sides)

If 9: x= x-4, then x=<br> 0 36<br> 18<br> 0 24<br> 6
madam [21]

Answer:

2±√13

Step-by-step explanation:

9/x=x-4

x² -4x - 9=0

x² -4x +4- 13=0

(x -2)²=13

x-2= ±√13

x= 2±√13
