You have 160 yards of fencing material. if you want to construct a rectangular pen whose width is between 10 and 20 yards, inclusive, what is the longest that such a pen can be, in yards?

70 yards

Step-by-step explanation:

we know that

The perimeter of the rectangular pen is equal to

we have

The width is between 10 and 20 yards inclusive

we know that

The longest pen will be for the smaller value of W

so

For W=10 yd

substitute in the equation of perimeter

solve for L

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

step-by-step explanation:

hope this !

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
