Consider the following. y1 = 1 − x2, y2 = x2 − 1 (a) find all points of intersection of the graphs of the two equations. point a (x, y) = ( ) (smaller x-value) point b (x, y) = ( ) (larger x-value) (b) find the unit tangent vectors to each curve at their points of intersection. point a y1 = ± (−1,2) √5 point a y2 = ± (1,2) √5 point b y1 = ± (1,2) 5 point b y2 = ± (1,−2) 5 (c) find the angles (0° ≤ θ ≤ 90°) between the curves at their points of intersection. (round your answers to two decimal places.) point a ° point b °

Which of the following lines is not parallel to the graph of y = 4x +7?

Which of the following multiplication expressions can be modeled by the tiles shown? check all that apply. 8(3) = 24 6(4) = 24 (3)(12) = 36 24(3) = 72 3(8) = 24 2(12) = 24

Use a calculator to verify that σ(x) = 62, σ(x2) = 1034, σ(y) = 644, σ(y2) = 93,438, and σ(x y) = 9,622. compute r. (enter a number. round your answer to three decimal places.) as x increases from 3 to 22 months, does the value of r imply that y should tend to increase or decrease? explain your answer. given our value of r, y should tend to increase as x increases. given our value of r, we can not draw any conclusions for the behavior of y as x increases. given our value of r, y should tend to remain constant as x increases. given our value of r, y should tend to decrease as x increases.
