Aparabola is represented by the equation x2 = 4y.

what are the coordinates of the focus of the parabola?

(0,4)
(0,1)
(1,0)
(4,0)

The answer is (B) (0, 1).

Step-by-step explanation: We are given to find the co-ordinates of the focus of the parabola represented by the following equation:

We know that the standard form of a parabola is given by

where the co-ordinates of the focus is (h, k + p).

In standard form, the parabola (i) can be written as

Comparing it with the general form (ii) of a parabola, we have

Therefore, the co-ordinates of the focus are

(h, k + p) = (0, 0 + 1) = (0, 1).

Thus, (B) is the correct option.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
