The probability is just 1/2 that the disc will result with the white side landing up.

There are two sides to the disc. If they are equally likely to happen, then the chance of either side is 1/2. It does not matter which number the flip is.

Which statement is true?
Nataliya [291]

Answer:

D

Step-by-step explanation:

We can see in the graph f(x) that the x intercept is (1,0).

In the table of g(x), we can see that the x intercept is (-1,0).

Since 1>-1, the x intercept of the graph f(x) is greater than the x intercept of graph g(x).

The graph of a quadratic function has roots at -3 and -7 and a vertex at (-5,4). What is the
ollegr [7]

The equation of the function in vertex form is y = -(x + 5)² + 4

<h3>What is quadratic equation?</h3>

A quadratic equation is a second-order polynomial equation in a single variable x , ax2+bx+c=0. with a ≠ 0 .

Given that the quadratic function has roots at -3 and -7 and a vertex at (-5,4).

We need to find the equation of the function in vertex form

equation of the function in vertex form.

As per the information given in the question,

The given roots of the function are -3 and -7,

y = a (x + 3) (x + 7)

y = a (x² + 10x + 21)

y = a (x² + 10x + 25 − 4)

y = a (x² + 10x + 25) − 4a

y = a (x + 5)² − 4a

The vertex is (-5, 4),

So, a = -1.

y = -(x + 5)² + 4

Hence, y = -(x + 5)² + 4  is the equation of the function in vertex form
