Answer:
5/4 is rational , 100 square root is irrational , 7.3 rational , 0.00247 is rational , 4/9 square root is irrational ,2/24 square root is irrational and 0.01 is rational :)
+ <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
Have fun
Answer:
73/39
Step-by-step explanation:
The slope of the given line is the coefficient of x in the given equation, which we recognize as being in slope-intercept form.
The slope of the perpendicular line will be the opposite reciprocal of this:
-1/(-39/73) = 73/39 . . . . slope of the perpendicular line
Answer:
The answer is A. the range is the set of all real numbers
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:

or

notice how neither the numerator or denominators are decimals?
