Which complex number is represented by the point graphed on the complex plane below

See this explanation:

for the given point x=3 and y=-4.

It means, z=3-4i. Answer; C.

Option (c)

Step-by-step explanation:

A complex number is a combination of a real number and an imaginary number.

Real number be represented on X axis and imaginary number be represented on Y axis.

Here real part of the complex number is 3 and the imaginary part is -4.

So, the complex number is 3 - 4i.

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
