The answer is True.
One radian is the central angle that subtends an arc length of one radius (s = r). Since all circles are similar, one radian is the same value for all circles. The arc measure of the central angle of an entire circle is 360º and the radian measure of the central angle of an entire circle = 2π.
Answer:
Equation -3x² - x + 3 = -3x² can not be solved using quadratic formula.
Step-by-step explanation:
1. -3x² - x + 3 = -3x²
Simplify above equation,
-3x² + 3x² - x + 3 = 0
or -x + 3 = 0 , Sine x² terms cancelled each other.
Hence this equation can not be solved using quadratic formula.
2. 0 =x² , yes here we can use quadratic formula
3. 0 = 2x²-1
Simplifying the above equation,
0 = 2x² - 1
1 = 2x²
x² =
Hence we can use quadratic formula here.
4. x²+3x-2 = 4x²- 5x - 1
Simplifying given equation,
x²+3x-2 = 4x²- 5x - 1
or x² - 4x² +3x +5x -2 + 1 = 0
or -3x² + 8x - 1 = 0
since x² term is here, hence we can solve this using quadratic formula.
75% of 500 is 375
so there are 375 seats filled.
so that mean's there 125 seats left
