Answer:
Solve the inequality as though it were an equation. The real solutions to the equation become boundary points for the solution to the inequality. Make the boundary points solid circles if the original inequality includes equality; otherwise, make the boundary points open circles.
Step-by-step explanation:
Answer:
-3/9x
Step-by-step explanation:
You rearrange for 'y' so divide both sides by it's coefficient which is 9.
An= A1 + d(n-1)
An= 170 + (-85)(n-1)
An=170-85(n-1)
An= 170-85n+85
Answer: An=255-85n
Answer:
Area of the sector = 29.48 square miles.
Step-by-step explanation:
Given:
Radius of a circle = 13 miles
Angle bounded by the arc = 20 deg
To find
Area of the sector bounded by 20 degrees.
Note: Area of a sector = 
Plugging the values in the equation.
⇒
⇒ 
⇒ 
square-miles
So the area of the sector bounded by 20 degree arc is 29.48 square miles.
