So based on the given illustration above of different graphs, the graph that depicts a complex number with i as the imaginary part would be the last one, graph D. <span>i as the imaginary part is the same thing as 1i, which makes this one as the answer. Hope this answers your question. </span>
Answer:
<u>Option 90°</u>
Step-by-step explanation:
AB is the perpendicular bisector of XY
The result of intersection will give 4 right angles
So,the measure of the angle of intersection when AB is the perpendicular bisector of XY = 90°
See the attached figure.
Answer:
x = - 1
Step-by-step explanation:
The equation of the axis of symmetry for a parabola in standard form
y = ax² + bx + c : a ≠ 0 is found using
x = - 
y = - x² - 2x - 5 ← is in standard form
with a = - 1 and b = - 2, thus equation of axis of symmetry is
x = -
= - 1
Equation of axis of symmetry is x = - 1
