Answer:
paprell lines
Step-by-step explanation:
No bc the width of the circular ring is only 12.67 inches
knowing circumference = pi * diameter, we can make the formula:
39.8 = (3.14)(diameter)
divide 39.8 by 3.15
diameter = 12.67 inches
12.67 inches is not greater than or equal to 18 inches
39/40 as a decimal is 0.975
Answer:
78.0 ft
Step-by-step explanation:
pythagoras theorem =
a² + b² = c²
a² + 36² = 85.9²
a² + 1296 = 7378.81
a² = 7378.81 - 1296
a² = 6082.81
a = √6082.81
a = 77.992....
so, a (rounded) = 78 ft :)
Answer:
where i^2 = -1 (minus one)
So, i^2 = -1
i^4 = (i^2)^2 = (-1)^2 = -1 X-1 = 1
like ;
i^32 = (i^2)^16 = (-1)^16 = -1 X -1 X-1 X -1 X-1 X -1 X-1 X -1 X-1 X -1 X-1 X -1 X-1 X -1 X-1 X -1 X
= 1
