Squares have equal side lengths, so that is why the question is only asking for one side length.
The area of a square is calculated using the formula s^2, where s stands for a side of the square.
To find the length of one side of the park, you can take the given area (3,600 m^2) and square root it. This would give you the length of one side of the square park.
√3,600 = 60
The length of one side of the park is 60 meters.
A central angle is an angle made by 2 radii. Seeing as they want the measure of the angle that represents industry pollution, that would be 40% of the total 360 degrees.
40% = 0.4
0.4 × 360 = 144
The measure is 144 degrees.
Answer:
4.09
Step-by-step explanation:
4.09 is your answer because all you need to do is add 3.34 and 0.75.
0.75 + 3.34 = 4.09
(9-3x^2)+(-8x^2+4x+5)=(-3x^2)+(-8x^2)+4x+9+5=-11x^2+4x+14
The answer is -11x^2+4x+14
