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)

What is the sum of the zeros of the function: y= x^2 - 5x + 6?
yawa3891 [41]

Answer:

Step-by-step explanation:

The zeros are the values of x for which y = 0

Quadratic formula

x = [5 ± √(5² – 4·1·6)] / [2·1]

 = [5 ± √1] / 2

 = [5 ± 1] /2

 = 2, 3

sum of zeros = 5

The domain of the following relation: R {(6, -2), (1, 2), (-3, -4), (-3, 2)} is
monitta
The domain is the set of possible inputs, i.e. the x-coordinates of the points.

Here those are 6, 1 and - 3 which in order is -3, 1, 6.

Then the answer is {-3, 1, 6}.

By the way note that this relation is not a function. Do you know why?

Because the image of -3 is not stated unambiguosly.

A game consists of rolling a colored die with three red sides, two green sides, and one blue side. A roll of a red loses. A roll
Pavel [41]

The expected value of the game is $2.00.

To Find: The fair price to pay to play the game of rolling a colored die with three red sides, two green sides, and one blue side

Now the question arises how to find the Fair Price

We are told that in the game of rolling the colored die;

A roll of a red loses.

A roll of blue pays 5.00 and A roll of green pays 2.00.

Now, the best game to get the fairest price is to play; RRRGGB  i.e (RED, RED, RED, GREEN, GREEN,BLUE)

Fair price = 2(3/6) + 6(1/6) + 0(2/6)

Fair price = $2
