Answer:
x = - 
Step-by-step explanation:
the equation of a circle centred at the origin is
x² + y² = r² ( r is the radius )
The radius of a unit circle is r = 1
substitute (x, -
) into the equation and solve for x
x² + (-
)² = 1²
x² +
= 1 ( subtract
from both sides )
x² = 1 -
=
( take square root of both sides )
x = ±
= ± 
since the point is in the 3rd quadrant then x < 0
x = - 
Answer:
It would cost $18 to ride the taxi 10 miles.
Based on function transformations, the graph of y= cos(2θ), is the same as the graph of <span>y= cos(θ), with a component B of 2, in which case, it means the period is the only thing that differs
well the period for this function will then be </span>

so, the graph of is, the same as y= cos(θ), just shrunk by half horizontally
