The vertex is (0,-8)
im not sure about axis of symmetry but i don’t think it has one
Answer:
C= b+ 0. 7
Step-by-step explanation:
C= b+ 0. 7
C= b+ 0. 7
Option B is correct
Why
3x=21
3(7) =21
21=21
Step-by-step explanation:
From the trigonometry:
tan θ = (sin θ) / (cos θ)
cot θ = (cos θ) / (sin θ)
∴ tan θ + cot θ = (sin θ) / (cos θ) + (cos θ) / (sin θ)
= [ sin² θ + cos² θ]/( sin θ cos θ) = 1 /( sin θ cos θ )
note : sin² θ + cos² θ = 1
