Lin has a drawing with an area of 20 in squared. If she increases all sides by a scale factor of 4, what will the new area be?
diamong [38]

The new area will be 320 in²

<em><u>Explanation</u></em>

Lin has a drawing with an area of 20 in² and she increases all sides by a scale factor of 4.

<u>The general rule</u> we need to use here.......

"<em>If the lengths of the sides in a shape are all increased by a scale  factor of  k, then the area will be increased by a scale factor of  k^2"</em>

Here the sides are increased by a scale factor of 4. So, the area will be increased by a scale factor of  (4)^2 =16

Thus, the new area will be:  (20*16)in^2 = 320in^2

The equation of a parabola is given.y=1/8x^2+4x+20 What are the coordinates of the focus of the parabola?
Lena [83]
He equation of a parabola is x = -4(y-1)^2. What is the equation of the directrix? 
<span>You may write the equation as </span>
<span>(y-1)^2 = (1) (x+4) </span>
<span>(y-k)^2 = 4p(x-h), where (h,k) is the vertex </span>
<span>4p=1 </span>
<span>p=1/4 </span>
<span>k=1 </span>
<span>h=-4 </span>

<span>The directrix is a vertical line x= h-p </span>
<span>x = -4-1/4 </span>
<span>x=-17/4 </span>

<span>------------------------------- </span>
<span>What is the focal length of the parabola with equation y - 4 = 1/8x^2 </span>
<span>(x-0)^2 = 8(y-4) </span>
<span>The vertex is (0,4) </span>
<span>4p=8 </span>
<span>p=2 (focal length) -- distance between vertex and the focus </span>
<span>------------------------------- </span>
<span>(y-0)^2 = (4/3) (x-7) </span>
<span>vertex = (7,0) </span>
<span>4p=4/3 </span>
<span>p=1/3 </span>
<span>focus : (h+p,k) </span>
<span>(7+1/3, 0)</span>
