Use the parabola tool to graph the quadratic function f(x)=−5x2−2.

alexira [117]

$\text{Consider the quadratic function}\\
\\
f(x)=-5x^2-2\\
\\
\text{For a quadratic equation, }f(x)=ax^2+bx+c, \text{ we know that the x-coordinate}\\
\text{of the vertex (h,k) is given by}\\
\\
h=\frac{-b}{2a}\\
\\
\text{on comparing the given equation with standard equation, we have}$

$a=-5, b=0, c=-2\\
\\
\text{so the x-coordinate of the vertex is }\\
\\
h=-\frac{b}{2a}=-\frac{0}{2(-5)}=0\\
\\
\text{so plug this vlaue of the h in the given function to get the y-coordinate}\\
\text{of the vertex. so}\\
\\
f(x)=-5(0)^2-2=0-2=-2\\
\\
\text{hence the vertex of the parabola is: }(h,k)=(0,\ -2)\\
\\
\text{A second point on the graph can be found by putting x=1, so }\\
\\
f(1)=-5(1)^2-2=-5-2=-7\\
\\
\text{so one other point on the parabola is }(1,-7)$

The grpah of the quadratic function is shown below:

100 POINTS! :)

nasty-shy [4]

Answer: So we'll use trig to solve this because it's a right triangle. The hypotenuse is the ladder (h) and the two smaller sides are the ground and the vertical wall (w).

That angle ladder makes with the ground = €

SOH: sin € = opposite/hypotenuse

No the ladder won't be safe!!!

Now let's make it safe:

The ladder's length (w) is constant, so stays 12

So now let's ask in an inequality what height will be safe (75° or less)

what does that mean?? well as long as you put the ladder against the wall so that the height from ground to top of the ladder is < 11.6 ft!!

Hope that helps! :-D
