An ellipse has vertices along the major axis at (0, 1) ) and ( -9)The foci of the ellipse are located at (0, - 1) and ( -7) The equation of the ellipse is in the form below. Which is a correct value for one of the variables shown in the equation ? ((y - k) ^ 2)/(a ^ 2) + ((x - n) ^ 2)/(b ^ 2) = 1 a = 10 b = 4 h = 3 k = 0

Isuck at math ; ^; m a student solved this problem and said the answer is 3 feet. chase had a roll of ribbon that contained 7 7/8  feet of ribbon. he cut off one piece that was 3 5/8  feet long and another piece that was 1 1/4  feet from the roll. how much ribbon was left on the roll? is the student's answer reasonable? yes, the answer is reasonable. no, the answer is not reasonable. it should be about 2 feet. no, the answer is not reasonable. it should be about 13 feet. no, the answer is not reasonable. it should be about 4 feet.

The customer price index(cpi), which measures the cost of a typical package of customer goods,was 208.8 in 2011 and 244.1 in 2016.let x=11 corresponding to the year 2011 an estimate to cpi into 2013 and 2014. assume that the data can be modeled by a straight line and the trend to continue idenfinitely.use data points to find such a line and then estimate the requested quantities
