Answer:
x = 3π/4, 5π/4
Step-by-step explanation:
cos(x+2π) = -√2/2, [0,2π]
cos(x)cos(2π)-sin(x)sin(2π) = -√2/2
cos(x) = -√2/2
x = 3π/4, 5π/4
Remember that the cosine function is periodic, so cos(θ+2π)=cos(θ).
We wish to know how much faster Grant rows than Arianna.
d=G-A and we want our answer is miles/hour so
d=(6mi/36min)(60min/hr)-(3520yd/20min)(mi/1760yd)(60min/hr)
d=10mph-6mph
d=4mph
So Grant rows 4 miles per hour faster than Arianna.
Answer:
18.84
Step-by-step explanation:
c=2×3.14(pi) × 6(diameter)/2
c=2×3.14×6/2
c=18.84
