Jacob has a certain amount of fencing he wants to use to make a dog run. If he makes the length 36 feet, the width will be 9 feet, but if he makes the length 40 feet, the width will be only 5 feet. Write an equation in the form y = mx + b that can be used to find the width, y, for any given length x.

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126

Which function can be used to model the monthly profit for x trinkets produced? f(x) = –4(x – 50)(x – 250) f(x) = (x – 50)(x – 250) f(x) = 28(x + 50)(x + 250) f(x) = (x + 50)(x + 250)

Find the solution on the interval [0, 2pi)
