For each value of k specified in parts (a)–(e), plot the set of points in the plane that satisfy the equation
x2 / k + y2 = 1.
a. k = 1
b. k = 2
c. k = 4
d. k = 10
e. k = 25
f. describe what happens to the graph of
x2k+ y2 = 1 as k → [infinity].

Suppose a least-squares regression line is given by modifyingabove y with caret equals 4.302 x minus 3.293. what is the mean value of the response variable if xequals20?

Anature center offer 2 guided walks. the morning walk is 2/3 miles. the evening walk is 3/6 mile. which is shorter

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
