<h2>
Answer:</h2>
option: B is the correct answer.
B. complex numbers.
<h2>
Step-by-step explanation:</h2>
We know that a complex number is always written in the form of :
a+ib
where a and b are real numbers and i is the square root of -1.
i is called an imaginary number.
If a>0 and b>0 then the point lie in the first quadrant.
if a>0 and b<0 then the point lie in the fourth quadrant.
if a<0 and b>0 then the point lie in the second quadrant.
if a<0 and b<0 then the point lie in the third quadrant.
6.51 - 9.32h = 1.02
9.32h = 6.51 - 1.02 = 5.49
h = 5.49/9.32 = 0.589
The unit of ratio is expressed as none. Ratio comprises of similar type of quantities so the units cancel out each other and thus there is no unit for a ratio. There is no unit for ratio. The numbers in the ratio will be of same unit - the unit can be meter or gram or litre or any such unit.
Answer:
On the circle
Step-by-step explanation:
Centre: (0,0)
Radius = sqrt(45)
Distance of (6,-3) from the centre is
Sqrt(6² + 3²) = sqrt(45)
Since the distance is equal to the radius, it's on the circle
