Answer:
Step-by-step explanation:
A <u>helix</u> is a curve for which the tangent makes a constant angle with a fixed line. The shortest path between two points on a cylinder (one not directly above the other) is a fractional turn of a helix, as can be seen by cutting the cylinder along one of its sides, flattening it out, and noting that a straight line connecting the points becomes helical upon re-wrapping (see attached diagram for helix).
The parametrization for the helix is
where 
is the radius of the helix, 
is the constant, and 
is the parameter
Multiply the coefficients and the powers of 10 with each other:
The numeric part simply yields
As for the powers of 10, you have to add the exponents, using the rule
So, we have
So, the final answer is
Answer:
<A = 16.82 degrees
Step-by-step explanation:
Tan^-1 = opposite/adjacent
Tan^-1 (13/43) = 16.82 degrees
Answer:
It cost $42 to rent a chain saw for 12 hours.
Step-by-step explanation:
Plug in 12 for h.
c = 3(12) + 6
c = 36 + 6
c = 42
