The regular period is 2pi. If you look up or type in a graphing calculator you can see that's when the sine function starts to repeat itself.
The answer is C: 
Starting with the given formula for the area, A = 1/2hb, the first step is to isolate h by using the multiplicative inverse of b, which is 
on both sides of the equation:
The result will be:
The last step is to use the multiplicative inverse of 
, which is 2 or 
to further isolate the variable <em>h </em>:
The formula for h will be:
which is the option C in your question.
Answer:
y=3/4x-2.5
Step-by-step explanation:
This is a straight line, so it would follow the equation y=mx+b. You can find the b value by looking at the y-intercept of the equation (where x=0), which in this case would be -2.5. Then, you can find the m value by comparing the two given points' locations. Slope is rise over run, so first you can find the rise. The y value moves from y=-4 to y=2, which is a value of 6 units upward. The points move from x=-2 to x=6, which is a distance of 8 units. Finally, put it into the rise over run pattern, giving you 6/8, which simplified is 3/4. This is your m value. Finally, plug in your two variable values into y=mx+b and you'll get y=3/4x-2.5.
