3/4min=3/8ft
4/4(1)=3/8+(1/4x3/8)
1min=3/64ft
pretty sure i did that right...if not I'm sorry
To convert to a decimal, divide by 100.
75 / 100 = .75
Sin 2θ = sin θ
2sin θ cos θ = sin θ
2cos θ = 1
cos θ = 1/2
θ = arccos(1/2) = 60° and 300°
θ = 60° and 300°
Answer:
Step-by-step explanation:
- x^2+8x-7<0
- x^2 + 8x + 16 - 23 < 0
- (x + 4)^2 < 23
- |x + 4| < √23 ≈ 4.8
