Webwork, TrigEquations, Problem #5

Find the principal root of this equation:

Tan(x) – 1 = 0

Tan(x) – 1 = 0
+1                  +1

Tan(x) = 1

(Tan-1 )Tan(x) = 1 (Tan-1 )

x = 45°

x = π/4

The Principal Root of this equation is π/4

Distance Formula, Midpoint and Circles, Perpendicular Bisector, Chapter 9, Section 9.1 Page 751, Question #5

Use the distance formula to find the distance between the two points. (6, 7) and (3, 2)

d = √ ( ( X2 – X1 )² + ( Y2 – Y1 )² )

d= √ ( ( 3 – 6 )² + ( 2 – 7 )² )

d= √ ( ( -3 )² + ( -5 )² )

d= √ ( 9 + 25 )

d= √ ( 34 )

Multiplication of Radicals, Chapter 6, Section 6.5 Page 528 Question #11

√2 * √10

=√(2* 10)

=√20

=√4 *√5

=2√5

Version D, Question 1

Ladies and gentlemen, welcome to the main event.  In the red corner,  majoring in Architectural technology, she hails from Rzeszow, Poland, and was rated by many professors with a passing grade – with 52 wins, 38 of them coming by the way of knockouts, and only one failed class- future student of a physics course, and future architect, she is, undefeated in five college classes, current City Tech student, Julia Prokop.
