The vertex of a parabola is (3,2). A second point on the parabola is (1,5).which of the following points is also on the graph?
vekshin1
+ <span>The vertex of a parabola is (3,2),
that means the parabola's equation is y=a(x-3)</span>²+2
+ <span>A second point on the parabola is (1,5) and we replace x=1 and y=5. We have: 
5</span>=a(1-3)<span>²+2  ,  so we have 4a=5-2 or a=3/4
So the equation is y=3/4 (x-3)</span>²+2

And by checking we have the point (5;5) is on the parabola

What makes 50.652 rational?
Ivanshal [37]
Remember a rational number is a number that can be written with two whole numbers in a fraction, for example, 0.25 can be written as 1/4 notice how, both, the numerator and denominator are whole numbers AKA Integers(numbers that aren't decimals or fractions).

any number that can't be written by whole numbers in the numerator or denominator is an irrational number, things like Pi, Pi cannot be written by two whole numbers in the fraction. 

50.652, is definitely rational because the fraction does not need decimal numbers in the numerator or denominator.

it can be written as:
50 \frac{50}{50} or \frac{12663}{250}

notice how neither the numerator or denominators are decimals?
