Answer:
Step-by-step explanation:
The given equation is
If we isolate , we can find the constant
So, the constant is .
Another proportions that have the same constant as the given equation are
Answer:
The constant of variation is 3
Step-by-step explanation:
Given.
And y is directly related to x
∝
Here k is constant of variation
--------------(1)
Put the and value in equation 1.
So, the constant of variation is 3.
Me i recently finished doing transformations. What's your problem?
Answer:
the first one
Step-by-step explanation:
9514 1404 393
Answer:
(a, b, c) = (-0.425595, 11.7321, 2.16667)
f(x) = -0.425595x² +11.7321x +2.16667
f(1) ≈ 13.5
Step-by-step explanation:
A suitable tool makes short work of this. Most spreadsheets and graphing calculators will do quadratic regression. All you have to do is enter the data and make use of the appropriate built-in functions.
Desmos will do least-squares fitting of almost any function you want to use as a model. It tells you ...
a = -0.425595
b = 11.7321
c = 2.16667
so
f(x) = -0.425595x² +11.7321x +2.16667
and f(1) ≈ 13.5

<em>Additional comment</em>
Note that a quadratic function doesn't model the data very well if you're trying to extrapolate to times outside the original domain.
