which equation is the quadratic variation equation for the relatonship? the variable y varies directly with x^2 and y=36 when x=

svetoff [14.1K]

For this case we have a direct variation of the form:

$y = kx ^ 2$

Where,

<em>k: proportionality constant </em>

We must find the value of k.

For this, we use the following data:

$y = 36\\x = 3$

Therefore, replacing values we have:

$36 = k (3) ^ 2$

Rewriting:

$36 = 9k$

Clearing the value of k we have:

$k = \frac {36} {9}\\k = 4$

Therefore, the direct variation equation is given by:

$y = 4x ^ 2$

Answer:

The quadratic variation equation for the relatonship is:

$y = 4x ^ 2$

Answer:

Step-by-step explanation:

Your exponential formula is in the form y = ab^x. In this form, the coefficient 'a' is the initial value, the y-intercept, the value when x=0. The value 'b' is the growth factor, which is 1 more than the growth rate per increment of x. This problem is asking for the growth rate to be expressed as a percentage.

__

Given p(x) = 78500(1.02^x), we can compare to the exponential function form to see that ...

a = 78,500
b = 1.02 = 1 +0.02 = 1 +2%

The value of x is zero in the year 2000, so the population that year is ...

p(0) = a = 78,500

The increase per year is the value of 'b' with 1 subtracted:

growth rate = 2% per year
