Hey there. Discrete data is usually date which is counted. Continuous data is data that can be measured, and can take any type of value. So for this, a) Continuous, b) Discrete c) Continuous, d) Discrete
Hopefully this should be right! :)
For this case we must find the perimeter of the fence, in a circular way, knowing that the perimeter of a circle is given by:
Where "r" represents the radius of the circle, in this case 
Substituting in the perimeter equation we have:
Rationalizing we have:
Taking out common factor

Answer:
Option C
36 inches are in one yard, 48 inches is 1.3 yards, 1.3 multiply by $3.75 would be approximately $4.87
Answer:
Answer:
A. 2 sinx cosx - 1 + 2 sin^2 x.
Step-by-step explanation:
sin2x = 2 sinx cosx
cos2x = cos^2x - sin^2x
So sin2x - cos2x = 2 sinx cosx - ( cos^2x - sin^2x)
But cos^2 x = 1 - sin^2 x, so we have:
2 sinx cosx - (1 - sin^2 x - sin^2x)
= 2 sinx cosx - 1 + 2 sin^2 x.
