Answer:
k = 4 + 5.10i , 4 - 5.10i
Step-by-step explanation:
8k - k^2 = 42
k^2 - 8k + 42 = 0
Completing the square:-
(k - 4)^2 - 16 +42 = 0
(k - 4)^2 = -26
k- 4 = +/-sqrt26
k = 4 + sqrt26 or 4 - sqrt26
k = 4 + 5.10i , 4 - 5.10i
A Proper fraction is where the numerator of a fraction is smaller than the denominator. Which means that the fraction will be less than 1
