Answer:

Yes.

Step-by-step explanation:

Though x and y can be achieved in a system of equations. The equation

x (t)=0.0411905(t^2)+(-0.164619)t+28.0114

And

y (t)=-0.024127(t^2)+(-0.591143)t+(-87.4403)

Are not system of equations but rather two different models of equations. Nevertheless

To find t in the first equation, x(t) has to be equal to zero.

When the t is substituted in the second equation, t will completely disappear. Given the value of y(t) and vice versa.

Exp.

100 $;
<span> discount of 20% => 80$;
</span> discount of <span>12%</span>% => 80 - 80*(12/100) = 71.4 $;

100 - (x/100)*100 = 71.4 => x = 29.6 => a single discount of 29.6%;

Find the value of f(-6).yy = f(x)108642-10-8-6-422468.10-2-4-6-8

Gennadij [26K]

The given graph is a downward parabola.

The roots of the equation is -2 and -8, and the vertex is (-5,7).

The general root form of parabola will be,

a(x-(-2))(x-(-8))=a(x+2)(x+8).

The value of a can be determined from the coordinate of vertex,

$\begin{gathered} y=a(x+2)(x+8) \\ 7=a(-5+2)(-5+8) \\ 7=a\times(-3)(3) \\ a=\frac{-7}{9} \end{gathered}$

Thus, the required quadratic is,

$f(x)=\frac{-7}{9}(x+2)(x+8)$

The value of f(-6) can be determined as,

$\begin{gathered} f(-6)=\frac{-7}{9}(-6+2)(-6+8) \\ =6.22 \end{gathered}$

Thus, the requried value of f(-6) is 6.22.
