Answer:
6
Step-by-step explanation:
There are 2 triangular bases, so there are 6 vertices.
I would try using order of operations (PEMDAS) & that should help ! im not good at math tho so :o

Answer:
cot(θ) = 4/5
Step-by-step explanation:
In the polar/rectangular coordinate representation (x, y) ⇔ (r; θ), we know that ...
(x, y) = (r·cos(θ), r·sin(θ))
From the various trig definitions and identities, we also know that ...
cot(θ) = cos(θ)/sin(θ) = (x/r)/(y/r) = x/y
For the given (x, y) = (-4, -5), the cotangent is ...
cot(θ) = -4/-5 = 4/5
One is x = 1, the other is x = 0.
