Answer:

Step-by-step explanation:
The vertex form of a parabola:

(h, k) - vertex
We have the vertex at (3, 2) → h = 3 and k = 2.
Substitute:

The point (4, 6) is on athe parabola. Put the coordinates of this point to the equation:
<em>subtract 2 from both sides</em>


Finally:
<em>vertex form</em>
<em>use (a - b)² = a² - 2ab + b²</em>
<em>use the distributive property</em>

<em>standard form</em>
Answer:
Step-by-step explanation:
The shaded area is the difference of the total area and the white triangle.
The white triangle has base of 9 cm and height of 4 cm.
<u>Its area is:</u>
<u>Area of rectangle:</u>
<u>The shaded area:</u>
Step-by-step explanation:
divided 20 by 5 times that by 4
20 divided by 5 is 4
4x4 is 16 its 16 you got it right
We use the graph of

as an example. The graph is shown in the first picture below
Let's take 2 as the value of the constant 'c'
The transformation of

gives the effect of halving the x-coordinates, as shown in the second picture.
The transformation of

, as shown in the third picture, gives the effect of doubling the y-coordinate
In conclusion,

gives the effect of halving the x-coordinates while

gives the effect of doubling the y-coordinates
419.10>419.099 419.10 is greater than 419.009
