प्रश्न
Divide. Write the quotient and the remainder.
21m2 ÷ 7m
उत्तर
21m2 ÷ 7m
`(21m xx m)/(7m) = 3m`
3m
`7m")"overline(21m^2)`
-21m2
0
So, quotient = 3m and remainder = 0.

The figure given alongside shows the path of a diver, when she takes a jump from the diving board. Clearly it is a parabola.
Annie was standing on a diving board, 48 feet above the water level. She took a dive into the pool. Her height (in feet) above the water level at any time‘t’ in seconds is given by the polynomial h(t) such that h(t) = -16t2 + 8t + k.
At what time will she touch the water in the pool?
An asana is a body posture, originally and still a general term for a sitting meditation pose, and later extended in hatha yoga and modern yoga as exercise, to any type of pose or position, adding reclining, standing, inverted, twisting, and balancing poses. In the figure, one can observe that poses can be related to representation of quadratic polynomial.
The graph of parabola opens downwards, if:
