The key features of polynomials are the vertex, axis of symmetry, x and y intercepts.

1. The degree will help you find the end behavior.

2. The vertex shows you where it changes concavity.

3. X and y intercepts give you a couple of points of reference.

4. Axis of symmetry is only applicable to even degree polynomials.

What’s the circumference, to this problem ?

yawa3891 [41]

Answer:

The formula to get the circumference of a circle is $C=2*\pi * r$ but in this case we see that a diameter is being used therefore we can get rid of the 2 and the r because that is what the diameter and just replace d into there like this $C=d*\pi$ .

We can then input the value and we get that $C=5*\pi$ which then just narrows down to $C=15.708$ .

Hope this helps! Let me know if you have any questions

Simplify (15x2 – 24x + 9) ÷ (3x – 3) = ?

larisa86 [58]

$\frac{15x^{2} - 24x + 9}{3x - 3} = \frac{3(5x^{2}) - 3(8x) + 3(3)}{3(x) - 3(1)} = \frac{3(5x^{2} - 8x + 3)}{3(x - 1)} = \frac{5x^{2} - 5x - 3x + 3}{x - 1} = \frac{5x(x) - 5x(1) - 3(x) - 3(-3)}{x - 1} = \frac{5x(x - 1) - 3(x - 1)}{x - 1} = \frac{(5x - 3)(x - 1)}{x - 1} = 5x - 3$

I believe the answer is the first one ! Keep in your mind that the first part of the ordered pair is always the domain , and the second part of the ordered pair is the range !!
