Explain how you know that 7/12 is greater than 1/3 but less than 2/3

velikii [3]

Well, it's greater than 1/3 because 1/3 of 12 is 4, and it's more than 4/12.
It's less than 2/3 because 2/3 of 12 is 8, and 7/12 is not 8/12.

Answer:

Part A

Eagle = 6 lbs * 60%

= 6 * 0.6

= 3.6 pounds

Bear = 105 lbs * 25%

= 105 * 0.25

= 26.25 pounds

3.6 + 26.25 = 29.85 pounds

Part B

Percent Increase = Change/Original * 100

= 10/105 * 100

= 9.52%

Find the values of b such that the function has the given maximum value.

gizmo_the_mogwai [7]

So, the equation has a leading term with a negative coefficient, and is a quadratic, meaning is a parabola opening downwards, so it goes up and up and up and then makes a U-turn then down down, so it has a maximum point, that is, at the vertex point

so.. where the dickens is the vertex at?
we're asked to make the vertex with a y-coordinate of 104, so the maximum value is 104

well
$\bf y = {{ a}}x^2{{ +b}}x{{ +c}}\qquad 
\left(-\cfrac{{{ b}}}{2{{ a}}}\quad ,\quad {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\right)\\\\
-----------------------------\\\\
\textit{so we want }\implies {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}=104
\\\\
\textit{let's take a peek at your equation}\quad 
\begin{array}{ccccllll}
f(x)=&-x^2&+bx&-17\\
f(x)=&-1x^2&+bx&-17\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}
\\\\
thus
\\\\
(-17)=\cfrac{b^2}{4(-1)}=104$

solve for "b"
