We are given the vertex of a parabola equal to (4, 0) and that the passes the point (6,1). In this case, it is assumed from the given that the parabola is facing upwards. In this case, the equation is (y-k) = 4a (x-h)^2 ; y = 4a (x-4)^2 when x is 6 and y is 1. then,
1 = 4a (6-4)^24a is equal to 1/4
the equation then is y = 1/4 (x-4)^2

What is the constant of proportionality for m=32•g

lina2011 [118]

Answer:

∴ Constant of Proportionality is 32

Step-by-step explanation:

Here Given;

$m=32\times g$ (equation-1)

$\frac{m}{g}=32$ (equation-2) (divide with 'g' on both side)

We know,

The Constant of Proportionality equation is given;

$y=k\times x$ (equation-3)

Where 'k' is known as Constant of Proportionality.

Comparing equation-1 and equation-3;

$y=m$ and $x=g$

Now equation-2 become;

$k=\frac{y}{x}$

Plug $y=m$ and $x=g$ in above equation;

$\frac{m}{g}=k$ (equation-4)

By comparing equation-2 and equation-4;

$k=32$

So Constant of Proportionality is 32
