A, B & C form the vertices of a triangle. CAB = 90°, ABC = 62° and AB = 8.7.
Calculate the length of BC rounded to 3 SF.

Find three consecutive numbers such that the sum of one-fourth the first and one-fifth the second is five less than one-seventh the third

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

How many solutions does the nonlinear system of equations graphed bellow have?
