Answer is C
The conjugate of the complex number a+bi is a-bi
you just reverse the sign of the imaginary part of the number ; so it is 4-51i
Rectangles are similar figures, thus if scaled copies of each other then the ratios of corresponding sides must be equal
compare ratios of lengths and widths
rectangles A and B
k =
=
← ratio of lengths
k =
=
← ratio of widths
scale factors are equivalent, hence rectangle A is a scaled copy of B
rectangles C and B
k =
=
← ratio of lengths
k =
=
← ratio of width
scale factors (k ) are not equal, hence C is not a scaled copy of B
rectangles A and C
k =
=
← ratio of lengths
k =
← ratio of widths
the scale factors are not equal hence A is not a scaled copy of C
Answer:
800 full marks
Step-by-step explanation:
295 + 25 = 320 marks required to pass
320 / 0.40 = 800 full marks
