I'm not sure what it is that you're looking for.
That'sa trinomial expression you've got there.
Its value depends on the value of theta.
Answer: Circle.
Depending on the angle and the place of intersection, when a plane intersects a cube, the sections created may be a square, a pentagon, a trapezoid, a triangle or a rectangle (even you can obtain an octagon), but you will never get a circle.
Answer:
The Ferris wheel rotates 18° between successive cars being at the bottom.
Explanation:
Angle inside a circle = 360°
No of cars in a Ferris wheel = 20
When the bottom of the ride is replaced by the next car, the angle rotated by Ferris wheel is same as the angle between two consecutive cars towards center of Ferris wheel.
Angle between two consecutive cars of Ferris wheel = 360/20 = 18°
The Ferris wheel rotates 18° between successive cars being at the bottom.
Hello! When you want to find the result of 5m+2 subtracted from 9m would equal -2m. Hope this helps. :)
