The average height of 12 Weeping Higan cherry trees planted in Washington, D. C. can be modeled by H(t) = 6.186 + 6.475 In (t), where t is the age of the tree in years. At the time of planting, the trees
were one year old and were all 6 feet in height. (
What is the average height of the trees at 7 years of age? (Round your answer to the nearest tenth of a
foot.)

Which of the following would be a correct step in proving that triangle abc is congruent to triangle cda? a. use a protractor to measure the angles and show that all the corresponding angles are equal in measure. this will allow you to prove congruence by aaa. b. show that segment ab is parallel to segment cd and segment ad is parallel to segment cb. this will allow you to prove congruency by asa. c. show that is segment ab is perpendicular to segment ad. this will allow you to prove congruence by sas. d. none of the above.
