Answer: 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:

x^2=4y.~~~~~~~~~~~~~~~(i)

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

(x-h^)2=4p(y-k),~~~~~~~~~~~~~~~~(ii)

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

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

x^2=4y\\\\\Rightarrow (x-0)^2=4\times 1(y-0)^2.

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

h=0,~k=0,~p=1.

Therefore, the co-ordinates of the focus are

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

Thus, (B) is the correct option.

The equation of the parabola is x^2 = 4y
The graph of this parabola is curved upwards with the vertex at the origin. The general formula of a parabola is
x^2 = 4ay
So
4a = 4
a = 1
Therefore, the focus of the parabola is
(0,1)

Step-by-step explanation:

tan x = 3/4

Tangent is opposite over adjacent, so draw a right triangle with angle x where the opposite side is 3 and the adjacent side is 4.

Use Pythagorean theorem to find the hypotenuse:

c² = 3² + 4²

c² = 25

c = 5

Sine is opposite over hypotenuse, so:

sin x = 3/5
