Answer:
∠5=∠7=∠6=∠8=143°
∠4=∠2=∠1=37°
Step-by-step explanation:
∠4=180-∠6=180-143=37°
Answer:
Area = length * width
Area = (x+6)(3x-1)
Area = 3x^2 - x + 18x - 6
Area = 3x^2 + 17x - 6 cubic units
Answer:
hyperbola
Step-by-step explanation:
A graphing calculator shows the equation is that of a hyperbola.
__
Multiplying by the denominator gives ...
r(2 -3sin(x)) = 1
2r -3y = 1 . . . . . . . . substituting y=r·sin(x)
2r = 1 +3y . . . . . . . .isolating r
4r² = 1 +6y +9y² . . squaring both sides
4(x² +y²) = 1 +6y +9y² . . . . . substituting x²+y² = r²
4x² -5y² -6y -1 = 0 . . . . . . . . general form equation of a hyperbola
