Answer:

X=39

Step-by-step explanation:

180 - 107 = 73

180 - 68 = 112

73 + 68 = 141

180 - 141 = 39

Convert r = 8cos θ to rectangular form.
skelet666 [1.2K]

Answer:

D

Step-by-step explanation:

To convert from polar to rectangular form

• x = rcosΘ , y = rsinΘ

• r = \sqrt{x^2+y^2} ⇒ r² = x² + y²

Given

r = 8cosΘ

r = 8 × \frac{x}{r} ( multiply both sides by r )

r² = 8x, hence

x² + y² = 8x ⇒ D

How many units long is a line segment whose endpoints have coordinates (-3,7) and (2,-5)?
Ilia_Sergeevich [38]

Answer:

D = 13 units

Step-by-step explanation:

<u><em>Using Distance Formula to find the length.</em></u>

Distance Formula = \sqrt{(x2-x1)^2+(y2-y1)^2}

D = \sqrt{(2+3)^2+(-5-7)^2}

D = \sqrt{(5)^2+(-12)^2}

D = \sqrt{25+144}

D = \sqrt{169}

D = 13 units

Which value of x must be excluded from the domain of the function, y = 9 / 2(x + 7)?
svlad2 [7]
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

I need help in this please! thanks​
svp [43]

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°
