Answer: 2.75
Step-by-step explanation: 2.5 + 0.25 + 0.25 = 3
Answer:
Positive angles located in the fourth quadrant may be described as<u> 270≤Ф≤360
.</u>
The option is
4. 270≤Ф≤360
Step-by-step explanation:
When the terminal arm of an angle starts from the x-axis in the anticlockwise direction then the angles are always positive angles.
For Example.
Quadrant I - 0 to 90°
Quadrant II - 90° to 180°
Quadrant III - 180° to 270°
Quadrant IV - 270° to 360° ( 4. 270≤Ф≤360 )
Hence,Positive angles located in the fourth quadrant may be described as<u> 270≤Ф≤360
.</u>
When the terminal arm of an angle starts from the x-axis in the clockwise direction than the angles are negative angles.
Quadrant IV - 0° to -90°
Quadrant III - - 90° to -180°
Quadrant II - -180° to -270°
Quadrant I - -270° to -360°
Answer:C
Step-by-step explanation:
(x+y)^10=x^10+10x^9y+45x^8y^2+120x^7y^3+210x^6y^4+252x^5y^5+210x^4y^6+120x^3y^7+45x^2y^8+10xy^9+y^10
Therefore they coefficient of x^5y^5 is 252
Let Child ticket be x
for adult 2.25x
2.25x* 9=520
solve for it .....
and 3x=520
solve for it ....
and sum of that two adult ticket and children ticket will be the revenue generate in ticket sold for that day . hope u can solve it
