The both on the right are the correct answers
Step-by-step explanation:
This is because rotational symmetry is defined as the property a shape has when it looks the same after some rotation by partial turns.
Answer: 40%
Step-by-step explanation: 100 ÷ 5 = 20 so 20 × 2 = 40
Answer:
1999
Step-by-step explanation:
y = 0.2313(y - 1992)^2 + 2.600(y - 1992) + 35.17
verify with known data point
y = 0.2313(2004 - 1992)^2 + 2.600(2004 - 1992) + 35.17
y = 0.2313(12)^2 + 2.600(12) + 35.17
y = 27.9873 + 28.6 + 35.17
y = 99.6772 which verifies our equation
65 = 0.2313x² + 2.6x + 35.17
0 = 0.2313x² + 2.6x - 29.83
quadratic formula
x = (-2.6 ±√(2.6² - 4(0.2313)(-29.83))) / (2(0.2313))
x = (-2.6 + 5.86) / 0.4626 = 7.05 years
7.05 = y - 1992
y = 1999.05
Volume of a cylinder is
![\pi r^2h](https://tex.z-dn.net/?f=%20%5Cpi%20r%5E2h)
, where r is the radius and h is the height.
This comes from the area of a circle being
![\pi r^2](https://tex.z-dn.net/?f=%20%5Cpi%20r%5E2)
. A cylinder is the area of the base circle multiplied by its height.
Using this formula, the volume of the given cylinder is
