Answer:

  P(x) = -1/2(x -3)²(x +3)

Step-by-step explanation:

When q is a root of the polynomial, (x-q) is a factor. This polynomial will be ...

  P(x) = a(x -3)²(x +3)

For x=0, the y-intercept will be ...

  P(0) = 27a = -13.5

Then the value of a is ...

  a = -13.5/27 = -1/2

The formula for P(x) is ...

  P(x) = -1/2(x -3)²(x +3) . . . . . . factored form

  P(x) = -0.5x³ +1.5x² +4.5x -13.5 . . . . standard form

Need help with figuring out this zingoes problem asap, willing to give brainliest!
muminat

Answer:

The yellow trapezoid, blue rectangle, and whatever that purple thing is are zingoes

Step-by-step explanation:

As far as I can tell, all the correct examples are

1) Symmetrical

2) Have a line splitting them symmetrically and does not go above or below the shape (Does that make sense?)

The wrong examples don't have any of the characteristics told above. For example, the square would be wrong because it doesn't even have a line

(P.S- This isn't my picture, just found it on the web. Shout out to whoever owns this)

Which of the following situations is NOT best modeled by a linear function?
GalinKa [24]

The height is not linear depending on time. Then the incorrect option is D.

<h3>What is a linear equation?</h3>

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

In linear motion, the height of the object is given as,

u = √(2gh)

From the first equation on motion, we have

v = u - gt

0 = √(2gh) - gt

2h = gt²

h = gt² / 2

Thus, the height is not linear depending on time.

Then the incorrect option is D.

More about the linear equation link is given below.
