One angle of an isosceles triangle measures 100°. which other angles could be in that isosceles triangle? choose all that apply. 20° 30° 50° 40° submit

Icould really use some with this question.

Write the expression as a single natural logarithm. 2 in a - 4 in y

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.
