First you have to define what a rational and irrational number is and they would be:
a / b, where b can never be 0.
Irrational are the numbers with non-periodic decimals, how the roots are not exact, the number pi, etc.
The student says "the difference of any irrational number and any rational number is rational"
The student's mistake is to use "any" since not any rational number would be the case that fulfills this.
That is, the correct thing is that there is an irrational number and a rational number in such a way that their difference is rational.
Answer:
67.5 deg
Step-by-step explanation:
A full circle is 2(pi) radians. It is also 360 degrees.
2(pi) radians = 360 deg
pi radians = 180 deg
3(pi)/8 rad * (180 deg)/(pi rad) = 67.5 deg
he result of adding two polynomials will always be another polynomial. A polynomial is an algebraic expression made up of the sum of monomials, which are products of numbers (coefficients) and variables in positive integer exponents.
Your answer would be A)
Hope this helps (:
Answer:
631
Step-by-step explanation:
4x105=420
102*102=204
Rewrite the equation:
