Let t and n be the tangent and normal lines to the ellipse x 2 + y 2 = 1 , < at any point p on the ellipse in the first quadrant. let xt and yt be the x- and y-intercepts of t and xn and yn be the intercepts of n. as p moves along the ellipse in the first quadrant (but not on the axes), what values can xt, yt, xn, and yn take on

Monthly water bills for a city have a mean of $108.43 and a standard deviation of $32.09. find the probability that a randomly selected bill will have an amount greater than $155, which the city believes might indicate that someone is wasting water. would a bill that size be considered unusual?

Eric has challenged himself to walk 24,000 steps in 4 days. if eric walks the same number of steps each day, which function represents the number of steps eric still needs to walk to reach his goal with respect to the number of days since he started his challenge? a. y = 8,000x − 24,000 b. y = -8,000x + 24,000 c. y = 6,000x − 24,000 d. y = -6,000x + 24,000
