Webwork, TrigEquations, Problem #5
Find the principal root of this equation:
Tan(x) β 1 = 0
Tan(x) β 1 = 0
+1 +1
Tan(x) = 1
(Tan-1 )Tan(x) = 1 (Tan-1 )
x = 45Β°
x = Ο/4
The Principal Root of this equation is Ο/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 = β ( ( X2 β X1 )Β² + ( Y2 β Y1 )Β² )
d= β ( ( 3 β 6 )Β² + ( 2 β 7 )Β² )
d= β ( ( -3 )Β² + ( -5 )Β² )
d= β ( 9 + 25 )
d= β ( 34 )
Multiplication of Radicals, Chapter 6, Section 6.5 Page 528 Question #11
β2 * β10
=β(2* 10)
=β20
=β4 *β5
=2β5
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 β 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.
