Answer:

Step-by-step explanation:

If you think in degrees easier than in radians, then make this conversion.

pi = 180 degrees

(3/2)*pi = (3/2) * 180 = 180 * 3/2 = 270

Sin(270) = -1

cos(270) = 0

==========

sin(270) * cos(270) = -1 * 0 = 0

fredd [130]

Answer:

37.5 miles per hour

Step-by-step explanation:

The question might be trying to confuse the reader. Point (1) which states the difference in weight does not show any evidence on how it affects the speed of both cyclist. Point (2) show an important point where the distance traveled is 75 miles.

Cyclist B, who leave point X at 2pm overtook cyclist A at 4pm, showing that the time it took for B to overtook A is 2 hours

Speed = distance / time

= 75 miles / 2 hours

= 37.5 miles per hour

Graph the system of inequalities
mihalych1998 [28]
Answer: To graph a linear inequality in two variables (say, x and y ), first get y alone on one side. Then consider the related equation obtained by changing the inequality sign to an equality sign. The graph of this equation is a line. If the inequality is strict ( < or > ), graph a dashed line.
