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?
Answer:
M = 45°
Step-by-step explanation:
a²=b²+c²-2bc Cos A
m² = n² + p² - 2np cos M
(5.1)² = (7.2)² + (5.3)² - 2(7.2)(5.3) cos M
26.01 = 51.84 + 28.09 - 76.32 cos M
-53.92 = -76.32 cos M
0.7065 = cos M
M = (0.7065)
M = 45°

Answer:
y=2x when x>5
Step-by-step explanation:
y=|x−5|+|x+5|
If x > 5 then x-5 is greater than 0 so we can remove the absolute value bars from the first term
x>5 then x+5 >0 so we do not need the absolute value bars on the second term
y = x-5 + x+5
Combine like terms
y = x+x-5+5
y = 2x
So the first step to solving this problem is to distribute the {1}{4}
to what's inside the parenthesis. This means multiply {1}{4} by 4x and 15.
After that, this is what you should have.
{4x}{4} + {15}{4} = 24
This should be simplified
1x = 24 - {15}{4}
{15}{4} is equal to 3.75
x = 20.25
20.25 is equal to {81}{4}
I think this is how it done
