Answer:
The correct option is D) No solution.
Step-by-step explanation:
Consider the provided equation.
We need to solve the above equation for x.
Subtract 16 from both the sides.
The absolute value of a real number "<em>a"</em> is the non-negative value of "<em>a"</em> without regard to its sign. It cannot be a negative number.
Thus the equation has no solution.
Hence, the correct option is D) No solution.

Answer:
distance = 994.75 miles
Step-by-step explanation:
given data
City A = 36°6′ = 36° + = 36.1° = 36.1° ×
= 0.6297 rad
City B = 21°42′ = 21° + = 21.7° = 21.7° ×
= 0.3785 rad
multiply by π/180 to convert the degree to radian
radius of Earth = 3960 miles
to find out
distance between City A and City B
solution
we first get here central angle between A and B city is
central angle between A and B city = 0.6297 rad - 0.3785 rad
and
now by arc length so we get distance
distance = 3960 miles × (0.6297 rad - 0.3785 rad )
distance = 994.75 miles
