P and q are complex numbers such that |p|=2/5x+1 , |q|=x+1 , and |p+q|=3x+2 .

On what interval must x fall?

[−5/2,0]
[−1,∞)
(−∞,−5/2]
[−1,0]

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

1. supplementary angles

2. acd and bcd

step-by-step explanation:

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
