You can add the numbers together so:
12.6
3.1
<u>+ 5.4
</u> 21.1
<u>
</u>Since the sum of the numbers is 21.1, it is greater than 20<u>
</u>
A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers.
All numbers that are not rational are considered irrational. An irrational number can be written as a decimal, but not as a fraction.An irrational number has endless non-repeating digits to the right of the decimal point. Although irrational numbers are not often used in daily life, they do exist on the number line. In fact, between 0 and 1 on the number line, there are an infinite number of irrational numbers!
Answer:
18
Step-by-step explanation:
2(18)=36
because the angles are equal
For a given (x,√x) on the curve, its distance to (5,0) can be calculated by pythagoras as:
D = √((5-x)² + √x²) = √(x²-9x+25)
We have to find the lowest D. To calculate that, we can find the minimum of x²-9x+25 which is at 9/2 (remember the -b/2a formula).
So the distance is minimal at the point (9/2, 3/√2)
