Answer:
D
Step-by-step explanation:
To convert from polar to rectangular form
• x = rcosΘ , y = rsinΘ
• r =
⇒ r² = x² + y²
Given
r = 8cosΘ
r = 8 ×
( multiply both sides by r )
r² = 8x, hence
x² + y² = 8x ⇒ D
Answer:
y = -3x + 19
Step-by-step explanation:
Once you start graphing for this equation you will see that -5,4 is one of the points.
Answer:
D = 13 units
Step-by-step explanation:
<u><em>Using Distance Formula to find the length.</em></u>
Distance Formula = 
D = 
D = 
D = 
D = 
D = 13 units
B) -7 because the dominator must be different by 0.
2(x + 7) ≠ 0 |divide both sides by 2
x + 7 ≠ 0 |subtract 7 from both sides
x ≠ -7
Answer:
θ = 85.93° (≈ 86°)
Step-by-step explanation:
arc length : 2πr = θ : 360°
7.5 : 2πr = θ : 360°
θ = (7.5 * 360°) / (2π*5) = 2700 / 31.42 = 85.93°
θ ≈ 86°
