(i) Find the value of m if the line K : mx - y + m -1=0 is 8 units
distance from the point (7.-5).
(ii)
Hence, find the measure of the acute angle between the line K and the line
3x-y+2=0.

Acompany is testing in comparing to lightbulb designs the box plot shows the number of hours that each lightbulb design last before burning out which statement is best supported by the information of the plot

Enter the number of complex zeros for the polynomial function in the box. f(x) = x+ + 5x² +6

F(x) = x2 − 9, and g(x) = x − 3 f(x) = x2 − 4x + 3, and g(x) = x − 3 f(x) = x2 + 4x − 5, and g(x) = x − 1 f(x) = x2 − 16, and g(x) = x − 4 h(x) = x + 5 arrowright h(x) = x + 3 arrowright h(x) = x + 4 arrowright h(x) = x − 1 arrowright
