Suppose you have 74 feet of fencing to enclose a rectangular dog pen. the function a=37x-x^2, where x = width, gives you the area of the dog pen in square feet. what width gives you the maximum area? what is the maximum area?

a). width = 37ft; area =721.5
b). width = 18.5ft; area = 342.3
c). width = 37ft; area = 342.3
d). width = 18.5ft; area =1026.8

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 shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1
