Find the y-intercept for the parabola defined by this equation: y= 4x2 – 7x-2

Marina CMI [18]

Answer:

(0,-2); The y-intercept is y=-2.

Step-by-step explanation:

Recall that the y-intercept is simply (0, y). In other words, we simply need to plug zero into the equation to acquire the y.

Thus:

$y=4x^2-7x-2$

$y=4(0)^2-7(0)-2$

$y=-2$

The number of possible seats is an illustration of permutation

There are 1728 possible sitting arrangements

<h3>How to determine the number of seats</h3>

From the question, we have the following highlights:

Chris can only take 1 seat (i.e. the central seat)
Jo can take 2 seats (i.e. the seats adjacent the central seat)
Alex, Barb and Dave can take 3! number of seats
Eddie, Fred, and Gareth can take 3! number of seats on the right of Chris.
The remaining 4 adults do not have preference, then they can seat in 4! ways

So, the number of sitting arrangement is:

$n = 1 * 2 * 3! * 3! * 4!$

Evaluate the product

$n = 1728$

Hence, there are 1728 possible sitting arrangements
