<p>Page 531 #5 can someone please explain to me how to solve the equation. I got the two side measurements to be 4 and then the formula is 1/2<em>B</em>H but I don't know how to finish it.</p>
<p>Then Page 532 #8 I don't understand how to do that one at all. </p>
<p>All help is appreciated, thank you.</p>
<p>lucky you, i just finished this section.</p>
<p>p. 531, #5:
first of all you don't need the two side measurements b/c ur finding area.
Thus, your just finding AC and the height which can easily be seen as 4.</p>
<p>height = 4
base = (5k-2k) = 3k</p>
<p>= 1/2 * 4 * 3k
= 2*3k
= 6k
6k = 18 ; k = 3. pwned.</p>
<h1>8, i got wrong. but its easy as ****.</h1>
<p>its a parabola, so one side of the parabola has an equal side.</p>
<p>so they give u f(3) and they want you to find b.</p>
<p>if f(3) is = to that point on the right side of the parabola, f(b) is on the complete opposite side. </p>
<p>f(b) = -1</p>
<p><strong>assuming u know functions.....</strong> which u should.</p>
<p>oh wow, very easy thanks for the help. I think i got thrown off on #8 because they weren't labeled and thats what I am used to. Thanks for the help.</p>
<p>yeah no problem. thats what this forum is for, giving help and receving help.</p>
