Answer: Since it is not a perfect square my answer is the square root of 261 or 16.16 which is rounded to the nearest hundredth.
Step-by-step explanation:
10^2 + b^2 = 19^2
100 + b^2 = 361
-100 -100
b^2 = 261
b=
Rational numbers are numbers that can be expressed as a fraction (ratio). Irrational numbers can not be expressed like that (like sqrt(2)).
To prove your statement, assume the opposite until you have a contradiction.
If the result of adding them would be rational, then your irrational number can be expressed as the difference of two rational numbers, which itself is also a rational number. That cannot be, because it should be an irrational number. This contradiction forces that rational + irrational = irrational.
You can reason the same way for multiplication. Suppose rational * irrational = rational, you find that your irrational can be expressed as the fration of two rationals, which is a contradiction.
we are given that
Michelle plotted 3 points from the equation y = 6 on this coordinate grid
It means that y-value will be 6 irrespective of any value of x
for exp: (1,6) (2,6) (3,6) ...
so, y-value must be fixed as 6
and x-value can be anything
so, we can see that the only point which has y-value =6 is (+4, +6)
so,
option-C........Answer
Length of an arc = theta/360 * 2pi * r
Distance traveled by the tape = 72/360 * 2pi * 18/2 = 18pi / 5
