Answer:
Step-by-step explanation:
You can’t just substitute 0 for θ. 0 is a constant, not a variable.
secθ = -13/5
cosθ = 1/secθ = -5/13
sin²θ = 1 - cos²θ = 144/169
sinθ = -12/13
cscθ = 1/sinθ = -13/12
tanθ = sinθ/cosθ = 12/5
cotθ = 1/tanθ = 5/12

Answer:
406 ml
Step-by-step explanation:
P1V1 = P2V2
(1) (.315) = (.775)(V2)
V2 = .406
1/6 acres in 1/4 hour
1/6 * 4 = 4/6 = 2/3
she mows 2/3 acres per hour
