Based on the residual plot shown, is a linear model appropriate for comparing tree age to basal area?
A forest management agency collects measurements
from beech trees in a public park. The age of many of
the trees is known, and the basal area—the area of land
occupied by the trunks of the trees-is also measured. A
least-squares equation that compares the basal area to
the age of each tree is given by area = 0.439(age) +6.226.

Is there a direction u in which the rate of change of f(x,y)equals=x squared minus 3 xy plus 4 y squaredx2−3xy+4y2 at p(1,2) equals 14? give reasons for your answer. choose the correct answer below. a. no. the given rate of change is smaller than the minimum rate of change. b. no. the given rate of change is larger than the maximum rate of change. c. yes. the given rate of change is larger than the minimum rate of change and smaller than the maximum rate of change.
