Suppose you just purchased a digital music player and have put 15 tracks on it. After listening to them you decide that you like

Lilit [14]

The given case is an example of permutation problem because the order is important given that you should like the first two songs. The sample space is calculated through the equation,
15P2 = 210
Then, there are 3 songs that you liked, the probability of picking 2 out of them is,
3P2 = 6
Dividing the latter by the earlier result will give us an answer of 1/35.

What function equation is represented by the graph? f(x)=14x+3 f(x)=−4x−3 f(x)=−14x−3 f(x)=14x−3

Vladimir [108]

See the explanation

<h2>Explanation:</h2>

Remember you have to provide complete questions in order to get exact answers. Here I'll provide a general explanation, so:

<h3>First.</h3>

$f(x)=14x+3$

The slope is:

$m=14$

The y-intercept is:

$b=3$

By using graphing tool, we get the first graph shown below.

<h3>Second.</h3>

$f(x)=-4x-3$

The slope is:

$m=-4$

The y-intercept is:

$b=-3$

By using graphing tool, we get the second graph shown below.

<h3>Third.</h3>

$f(x)=-14x-3$

The slope is:

$m=-14$

The y-intercept is:

$b=-3$

By using graphing tool, we get the third graph shown below.

<h3>Fourth.</h3>

$f(x)=14x-3$

The slope is:

$m=14$

The y-intercept is:

$b=-3$

By using graphing tool, we get the fourth graph shown below.

F(3)= 5x^2 - 4x + 9<br> evaluate this quadratic function

Neporo4naja [7]

Answer:

$f(3) = 38$

Step-by-step explanation:

Given the quadratic function

$f\left(x\right)=\:5x^2\:-\:4x\:+\:9$

Evaluating the quadratic function

$f\left(x\right)=\:5x^2\:-\:4x\:+\:9$

substitute x = 3

$f\left(3\right)=\:5\left(3\right)^2\:-\:4\left(4\right)\:+\:9$

$f(3) = 45-16+9$

$f(3) = 38$

Therefore,

$f(3) = 38$
