Step-by-step explanation:

18 minutes in total.

4 1/2 minutes per pot.

so, all we need to do is find out how often 4 1/2 fits into 18. that is what division is for.

18 / (4 1/2)

4 1/2 = 2×4/2 + 1/2 = 8/2 + 1/2 = 9/2

18 / 9/2 = 18/1 / 9/2 = 2×18 / 9×1 = 36/9 = 4

there are 4 coffee pots.

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:

$y=-0.215x^2+35$
