Mathematics

Serhud [2]3 years ago
5 0

Answer:

Arc length is 12436.8m

Step-by-step explanation:

arc length  = \frac{M degree}{360degree} * πD

where M is the angle measure of the arc

and D is the diameter

considering the earth as a circle and half the earth as a semi circle the angle measure of the arc will be = 180 degrees

\frac{180}{360} * π * 7917.5 = 12436.8m

Explain whether each equation is a linear equation.
Aleksandr-060686 [28]

Answer:

3. Not linear

4. Linear

Step-by-step explanation:

3. The equation has an exponent on the x. Since x is squared the graph is a parabola. The graph is a curve, not a line, so it is not linear.

4. Both the x and y have no exponent (which is an exponent of 1) The graph will be a line. This is a linear function.
