Answer:

\frac{2\pi}{ 3}  = 120 \: degrees

arc PR = 2\pi.r( \frac{120}{360} )

= 2\pi(8) \times  \frac{1}{3}

=  \frac{16\pi}{3}

a hiking path is represented by the equation y=3/8x on a coordinate map. The county would like to create a parallel path for bik
stepladder [879]

Answer:

The equation of the bike path on a coordinate map is represented by y = \frac{3}{8}\cdot x +1.

Step-by-step explanation:

From Analytical Geometry, we know that resultant parallel line is a translated version of parent line. Two lines are parallel to each other when they share the same slope. The resultant line can be construted from slope-point form:

y-y_{o} = m_{\parallel}\cdot (x-x_{o})

Where:

x_{o}, y_{o} - Components of known point, dimensionless.

m_{\parallel} - Slope of the parallel line, dimensionless.

In addition, a line has also this form:

y = m\cdot x + b

Where:

x - Independent variable, dimensionless.

y - Dependent variable, dimensionless.

m - Slope, dimensionless.

b - y-Intercept, dimensionless.

Given that parent function is y = \frac{3}{8}\cdot x, the slope of the resulting line is m_{\parallel} = \frac{3}{8}. Now, if x_{o} = 16 and y_{o} = 7, we obtain the equation of the line:

y-7 = \frac{3}{8}\cdot (x-16)

y = \frac{3}{8}\cdot x +1

The equation of the bike path on a coordinate map is represented by y = \frac{3}{8}\cdot x +1.
