Acell phone plan has a monthly cost that is shown in the table below. what is the correct statement regarding the average rate of change during the 40-minute time of talk?
total minutes of talk time monthly cost of cell phone
0 $19.95
10 $20.45
20 $20.95
30 $21.45
40 $21.95
a.) the average rate of change is $0.50, meaning that for each minute of talk time, the monthly bill increases by $0.50.
b.) the average rate of change is $0.50, meaning that for every ten minutes of talk time, the bill increases by $0.50.
c.) the average rate of change is $0.05, meaning that for each minute of talk time, the monthly bill increases by $0.05.
d.) the average rate of change is $0.05, meaning that for every ten minutes of talk time, the bill increases by $0.05.

In δabc shown below, ∠bac is congruent to ∠bca: triangle abc, where angles a and c are congruent given: base ∠bac and ∠acb are congruent. prove: δabc is an isosceles triangle. when completed (fill in the blanks), the following paragraph proves that line segment ab is congruent to line segment bc making δabc an isosceles triangle. (4 points) construct a perpendicular bisector from point b to line segment ac . label the point of intersection between this perpendicular bisector and line segment ac as point d: m∠bda and m∠bdc is 90° by the definition of a perpendicular bisector. ∠bda is congruent to ∠bdc by the definition of congruent angles. line segment ad is congruent to line segment dc by by the definition of a perpendicular bisector. δbad is congruent to δbcd by the line segment ab is congruent to line segment bc because consequently, δabc is isosceles by definition of an isosceles triangle. 1. corresponding parts of congruent triangles are congruent (cpctc) 2. the definition of a perpendicular bisector 1. the definition of a perpendicular bisector 2. the definition of congruent angles 1. the definition of congruent angles 2. the definition of a perpendicular bisector 1. angle-side-angle (asa) postulate 2. corresponding parts of congruent triangles are congruent (cpctc)
