Zinaida [17]

Answer:

y=-0.215x^2+35

Step by Step:

Let, $h=0$ , $k=35$ , $x=8$ , $y=21$

We know that, the general equation of the parabola.

$y-k = a(x-h)^2$

$\Rightarrow y=a(x-h)^2+k .........(i)$

Substitute the value of $h, k, x, y$ in equation $(i)$ and find the value of $a.$

$21=a(8-0)^2+35$

$\Rightarrow 21=a\times 8^2+35$

$\Rightarrow 21=64a+35$

$\Rightarrow 64a=21-35$

$\Rightarrow 64a=-14$

$\Rightarrow a=\frac{-14}{65}$

$\Rightarrow a=-0.215$

Hence, the equation of the parabola is:

$y=-0.215x^2+35$

which inequality does the graph represent??? if you could answer that would greatly be appreciated (∧_∧)

tiny-mole [99]

When there is a dotted line it means its either this symbol < or this one >. The y-intercept is 25. Now go up 4 spaces and one space to the left that is your slope. We call that "Rise over Run". So the last choice is your final answer.
I hope this helps love! :)
