Multiple Choice

Plot the complex number and find its absolute value. ​
-5 + 9i
​


A) ​  Plot the complex number and find its absolute value. ​ -5 + 9i ​ A) ​   ​ |-5 + 9i| =  2 \sqrt { 19 }  B) ​   ​ |-5 + 9i| =  2 \sqrt { 7 }  C) ​   ​ |-5 + 9i| =  \sqrt { 106 }  D) ​   ​ |-5 + 9i| =  \sqrt { 22 }  E) ​   ​ |-5 + 9i| =  \sqrt { 86 } ​
|-5 + 9i| = 2192 \sqrt { 19 }
B) ​  Plot the complex number and find its absolute value. ​ -5 + 9i ​ A) ​   ​ |-5 + 9i| =  2 \sqrt { 19 }  B) ​   ​ |-5 + 9i| =  2 \sqrt { 7 }  C) ​   ​ |-5 + 9i| =  \sqrt { 106 }  D) ​   ​ |-5 + 9i| =  \sqrt { 22 }  E) ​   ​ |-5 + 9i| =  \sqrt { 86 } ​
|-5 + 9i| = 272 \sqrt { 7 }
C) ​  Plot the complex number and find its absolute value. ​ -5 + 9i ​ A) ​   ​ |-5 + 9i| =  2 \sqrt { 19 }  B) ​   ​ |-5 + 9i| =  2 \sqrt { 7 }  C) ​   ​ |-5 + 9i| =  \sqrt { 106 }  D) ​   ​ |-5 + 9i| =  \sqrt { 22 }  E) ​   ​ |-5 + 9i| =  \sqrt { 86 } ​
|-5 + 9i| = 106\sqrt { 106 }
D) ​  Plot the complex number and find its absolute value. ​ -5 + 9i ​ A) ​   ​ |-5 + 9i| =  2 \sqrt { 19 }  B) ​   ​ |-5 + 9i| =  2 \sqrt { 7 }  C) ​   ​ |-5 + 9i| =  \sqrt { 106 }  D) ​   ​ |-5 + 9i| =  \sqrt { 22 }  E) ​   ​ |-5 + 9i| =  \sqrt { 86 } ​
|-5 + 9i| = 22\sqrt { 22 }
E) ​  Plot the complex number and find its absolute value. ​ -5 + 9i ​ A) ​   ​ |-5 + 9i| =  2 \sqrt { 19 }  B) ​   ​ |-5 + 9i| =  2 \sqrt { 7 }  C) ​   ​ |-5 + 9i| =  \sqrt { 106 }  D) ​   ​ |-5 + 9i| =  \sqrt { 22 }  E) ​   ​ |-5 + 9i| =  \sqrt { 86 } ​
|-5 + 9i| = 86\sqrt { 86 }
