Answer:
cosθ = -√(35/36)
tanθ = -1/√35
Step-by-step explanation:
We know that
sin²θ + cos²θ = 1
(1/6)² + cos²θ = 1
1 - (1/6)² = cos²θ
35/36 = cos²θ
sec θ = 1/ cosθ
1/ secθ = cos θ
Because secθ < 0, 1/ secθ would also be < 0, so cos θ < 0
cosθ = -√(35/36)
tanθ = sinθ/cosθ = (1/6)/-√(35/36)
= (1/6) / -(√35/6)
= -1/√35
60 seconds into a minute so the equation is 22 x 60 = 1320
10/12 - 9/12 = 1/12 is the answer. you had to change the denominator so that they are the same
Ei = 9r......E = (9r)/ i
i = 18
r = 5
now we sub
E = (9 * 5) / 18
E = 45/18
E = 2.5......the pitchers ERA is 2.5
The first equation tells you that . If you substitute this expression for in the second, we have
And we can deduce
