The given expression :
For coordinates:
put x = 0 then :
Coordinate : (x, y) = (0, 1)
Put x= 1 and simplify :
Coordinate : (x, y) = ( 1, 0.5)
Put x = (-2) and simplify :
Coordinate : (x, y) = ( -2, 4)
Put x = (-3) and simplify :
Coordinate : (x, y) = (-3, 8)
Substitute x = (-1) and simplify :
Coordinate : (x, y) = ( -1, 2)
So, the coordinates are :
The graph is :
Answer:
Θ = 46°
Step-by-step explanation:
the angle between a tangent and a radius at the point of contact is 90° , so
∠ ABO = 90°
since OB = OD ( radii of circle ) then Δ BOD is isosceles and
∠ OBD = ∠ ODB = 22°
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ AOB is an exterior angle of the triangle , then
∠ AOB = 22° + 22° = 44°
the sum of the 3 angles in Δ AOB = 180° , then
Θ + 44° + 90° = 180°
Θ + 134° = 180° ( subtract 134° from both sides )
Θ = 46°
